My chainsaw seemed to run a little hotter, which was helpful, but I wonder if this is not the best thing for the machine. Any thoughts? Thanks. The manual with my saw recommends a minimum of 89 octane... I use ethanol free premium gas along with synthetic 2 cycle oil (STIHL HP Ultra) that has fuel stabilizers. In the past year or so one of the chain convenience stores started carrying ethanol free premium gas and they are adding store locations steadily over time--I've got one 7/10ths of a mile from my house now. I started using this mix in all my Stihl 2 stroke equipment (string trimmer, hedge clipper, chainsaw), and the gas in my mower, and everything runs better. I would expect your saw to run cooler, and better, with the premium fuel as compared to say 87 octane based on my saw's manual: "Use mid-grade unleaded gasoline with a minimum octane rating of 89 and no more than 10% ethanol content." "Fuel with a lower octane rating may increase engine temperatures. This, in turn, increases the risk of piston seizure and damage to the engine." John I run nothing but ethanol free premium gas in ALL of my small engine equipment. For the small amount of fuel I put through them in a year, the difference in cost is a non-issue, particularly considering the possible costs of the alternatives. A screwed up carb or a scuffed piston or siezed engine is too costly to consider trying to save the 7 cents a liter or whatever. I do the same. I have a 4 cycle mini-rototiller with a Honda mini engine. It has been a problem from new, had it serviced and not much better. It was hard to start and would stall after running a few minutes, and then only run a minute or so after starting hot. This was with regular 87 gas. I also have a Honda weed wacker with a mini 4 stroke engine that runs fine with regular 87 fuel. Switched all my small engines to Shell premium, they run great and even the difficult mini-rototiller Honda now runs properly with only a change of fuel to premium. The added cost of premium is insignificant compared to frequent servicing required when they don't run properly. By the way, I have a Honda self-propelled walk behind mower that is now over 25 years old and has never needed service other than oil changes. It starts on the first pull. Those things are sensitive, and with no carb adjustment available they run just enough too lean on Hooch that they hardly run at all.. |

Sure, it won't do any damage to my vehicle but why would I want to get 30% less millage and pay almost the same price as gas? It ****es me off that the corn ethanol is mandated by the government to subsidize their failed corn farmer policies. We're paying for it with our tax dollars, yet it still costs almost as much as regular gasoline. So why the #U@& would I pay as much for it as gas and get 30% lower millage. If I'm subsidizing it, it should be much cheaper. Also, how the h3!! does it fluctuate perfectly in sync with gasoline prices when it only contains 15% gas? When gas is 2 bucks a gallon, E-85 is around 2 bucks. When gas is 4 bucks a gallon, E-85 is around 4 bucks when there's no fluctuation in the ethanol supply and the price is controlled. Who's doing that math? What a rip-off. -- -MIKE- "Playing is not something I do at night, it's my function in life" --Elvin Jones (1927-2004) -- http://mikedrums.com ---remove "DOT" ^^^^ to reply |

I've seen electric Sithl saws used indoors along with electric powered bandsaw mills. Electric chainsaws have definitelty been around for a while now, but my point was the real usefulness of these saws - not the availability of them. As I said - unless you're looking to cut up a small limb a coupld of times a year, they are not practical. I live in a log home, so I own an electric chainsaw (not one of my Stihls) - saves on the fumes, etc. (When you remodel; a log home, a chainsaw is your tool of choice). That kind of use though is not what 99% of people think about when they thinki about chainsaw use. -- -Mike- |

I don;t know if the saw is stock or not - I've only owned it for about 25 years. |

I took down a complete cherry tree except for the bottom 4 feet of trunk with a 10 inch electric on a pole. Line powered - not battery - in less ths 3 hours. The tree was higher than my 2 story house. I used the electric pole saw because there was no way I was taking the remington up into the tree. I limbed it from a 12 foot stepladder with the pole saw completely extended. After I had it down to the 4 or 5 foot stump I pulled out the remington, the noticed there was a tree service truck just finishing up down the street so I asked them how much to finish the stump and chew up all the branches so I didn't need to haul it to the dump. Less than an hour later there was nothing left but some leaves and twigs. (and the stump chunks I had other plans for) |

I don;t know if the saw is stock or not - I've only owned it for about 25 years. Ahhh-So... That makes more sense. Pulling it over those couple of times on full choke is the same thing as if you had the ignition on. More like the way my saws behave. Stone cold, my big saw usually takes 3 or 4 pulls on full choke before it coughs, then starts on one or two more pulls with the choke set back to half. The little saw generally starts with about the same amount of pulls - maybe a pull less. As an aside, the saw I had prior to buying my 361 was an 034AV (Stihl). I owned it for twenty years or more and it was a great saw - never let me down. But - all of its life it was a cold blooded saw - right from day one. Seemed to pull it forever to get it started cold. Carb was adjusted correctly, good spark plug, etc - but.. it got you warmed up for a day of firewood just in the process of starting it. One day it would not start. I knew that could be fixed, but I used it as my excuse to buy a new saw. Bought my 361 and had the guys at the shop go through the 034, which my son took posession of when they were done. If I remember correctly, they put a carb on it - or maybe they rebuilt the carb, not sure. Once my son got it, that thing started like it never had before - sometimes easier than my new saw. Still running strong for him now, and he puts up about the same amount of firewood as I do every year. -- -Mike- |

Some of that is profiteering, but a big part of it is that corn ethanol requires a fair bit of fuel to make, and it can't be stored all that long, so the cost of making it tracks the cost of fuel fairly well. In Brazil, where ethanol comes from sugar cane, it takes much less energy to make it, and almost all comes from burning bagasse rather than other fuels. John |

Antiknock Index and Octane Rating are the same thing. You're trying to sound intelligent there, but you're shooting yourself in the foot... t octane only goes to 100 because you can NOT have aoiso-octane/heptane mixture more than 100% iso-octane.Check your facts.

I don't know why Canada is different, but I suspect it's due to tax policy. It's because if you have to sell a certain amount of ethanol, put it where you will sell it fastest. In the US, ethanol is used because: a) it's an effective octane booster b) it's cheap compared to the alternatives c) the energy act of 2007 provides Federal incentives d) it does not have the legal liabilities of MBTE Incidently, ethanol isn't "added to gas at 10%". The amount used varies, from 5% to 10%, depending on the octane rating desired. Mabee in the US of A, but not here in Canada. Ethanol is used as an oxygenator up here. The extra octane is just a "bonus" if you can call anything that reduces the energy output of a fuel a "bonus" Up here it is "may contain up to 10% ethanol by volume" John |

What I will say is that no 40v saw will keep up with my Stihl 361 out in the woods for the day of puttin up firewood. Show me one that will drive a 25" bar, and cut all day long, as fast as mine will hog through a 36" maple. Going back to what my original point was - I was responding to John's claim that the gasoline saw was on its way out in deference to electric models. I simply disagree with this asseriton and think it only comes from a guy that does not use a chainsaw. -- -Mike- |

I don't know why Canada is different, but I suspect it's due to tax policy. It's because if you have to sell a certain amount of ethanol, put it where you will sell it fastest. In the US, ethanol is used because: a) it's an effective octane booster b) it's cheap compared to the alternatives c) the energy act of 2007 provides Federal incentives d) it does not have the legal liabilities of MBTE Incidently, ethanol isn't "added to gas at 10%". The amount used varies, from 5% to 10%, depending on the octane rating desired. Mabee in the US of A, but not here in Canada. Ethanol is used as an oxygenator up here. The extra octane is just a "bonus" if you can call anything that reduces the energy output of a fuel a "bonus" Up here it is "may contain up to 10% ethanol by volume" John Exactly! Typically alcohol reduces gas mileage. My Tundra which was designed to run or regular gets better gas mileage with premium from the same gasoline station. Now that the price difference out weighs the gas mileage benefits I have cut back from using premium and over all my gas mileage has suffered. Now there are other reasons that I get better gas mileage from premium but most likely the lack of alcohol is just one of them. |

That very well may be however it is only in the Premium grade Shell gasoline. Even their web site indicates this. If you want my opinion, the best gasoline additive is Chevron's Techron. But I don't think there's much difference between any of the top brands. Techron is not bad at all. I was selling Techron before it was added to gasoline. I learned about Techron through General Motors, they were selling it as a fuel additive to combat the injector contamination issues that they were having in the 80's. And it worked well. It came in a 16 or 32 oz bottle IIRC. It was only later on that Chevron began marketing it with their gasoline in Texas. Well if it was advertized alcohol free they would certainly catch a bunch of flack from the tree huggers. Down here their pumps only claim "May" have up to 10% alcohol. Same here - I think that's a legal requirement, and is the same wording everywhere in the US. Absolutely a requirement when they don't know which fuel you are going to choose. It is a blanket statement that covers all the bases. Mid grade is blended at the station pump. Next time I'm in Texas I'll have to look at the pumps and see if the premium is marked different (last time I got gas in TX was at the Buck-ees north of Houston on US290, and I was so overwhelmed at the size of it - must have been 100 pumps - I didn't pay attention to that sort of detail).

Techron is good, but the "nitrogen enriched" is a LITTLE more than advertizing blather. There is a big difference between run-of-the -mill gasoline and third tier. This is true but to be clear Tier 1 is not strictly the premium fuel, rather the brand. Exxon has always had detergents and additives but only relatively recently has qualified as a Tier 1 provider. The Top Tier standards must apply to all grades of gasoline that a company sells, whether it is economy (low-octane) or premium (high-octane).[2] However, premium gasolines may contain even higher levels of detergent additives. https://en.wikipedia.org/wiki/Top_Ti...rgent_Gasoline |

I had gas and then electric. I can/could saw 6~8" diameter oak limbs with no hesitation. Granted that because the electric simply runs slower than the gas does at full throttle the gas cut faster. But over all in the past 20 or so years the electric has had much less down time than the gas did, so in the time spent futzing with the gas saw, including mixing and filling with gas, the electric required less of MY time , which IMHO is all that counts. Gas is great when that is all that will work but with electricity available I will stick with an electric for any trimming including the use of my electric recip saw for 4" and under branches. |

My chainsaw seemed to run a little hotter, which was helpful, but I wonder if this is not the best thing for the machine. Any thoughts? Thanks. I use only ethanol free gas for all of my small engines and my farm tractor. Around here the only ethanol free gas you can get is Premium. I've never noticed any difference in how hot my engines run on it, and I have two Stihl chainsaws that I use the stuff in. The place where I get my saws serviced strongly recommends only using ethanol free fuel in them, which by definition, means premium gas. I've not heard of any ramifications from using the stuff. Using higher octane than required won't hurt anything except your wallet. Indeed - but using that ethanol crap will hurt yer pocketbook even more. Ask me how I'd know - have you priced the newer fuel lines that are impervious to ethanol? Of course you never really come to understand these costs until that day you go out to use the machine and it's pouring fuel all over itself through the deteriorated lines. It's almost highway robbery! Don't even get me going on trying to rebuild carbs on small tools like string trimmers... I have a flex fuel and I refuse to use the E-85 stuff. Sure, it won't do any damage to my vehicle but why would I want to get 30% less millage and pay almost the same price as gas? It ****es me off that the corn ethanol is mandated by the government to subsidize their failed corn farmer policies. We're paying for it with our tax dollars, yet it still costs almost as much as regular gasoline. So why the #U@& would I pay as much for it as gas and get 30% lower millage. If I'm subsidizing it, it should be much cheaper. Also, how the h3!! does it fluctuate perfectly in sync with gasoline prices when it only contains 15% gas? When gas is 2 bucks a gallon, E-85 is around 2 bucks. When gas is 4 bucks a gallon, E-85 is around 4 bucks when there's no fluctuation in the ethanol supply and the price is controlled. Who's doing that math? What a rip-off. It is the old term, "what the market will bear". Same goes for the industry as a whole. Ten years ago gasoline was at record highs. Prices were sold as supply and demand. There was no shortage, just a lack of competition. So again, "what the market would bear". In recent years there has been more competition and even more supply and up until relatively recently the much lower prices at the pump was profitable for all producers. Supply and demand could finally be the reason for prices. NOW there is a huge supply with basically the same demand. More competition has ultimately driven prices down at the pumps, not the fact that there is more supply. BUT some HUGE producers are continuing to over produce, and at a loss, to drive the smaller competitors out of business. Then there will be less competition and prices will absolutely go back up to "what the market will bear". There is a reason the Shell, Chevron, Exxon, Phillips, Conoco, Texaco, and "name your major brand" have joined forces, to eliminate half the competition. |

I've seen electric Sithl saws used indoors along with electric powered bandsaw mills. Electric chainsaws have definitelty been around for a while now, but my point was the real usefulness of these saws - not the availability of them. As I said - unless you're looking to cut up a small limb a coupld of times a year, they are not practical. I think you points would make more sense if you pointed out that gas works most anywhere and would probably last longer with day to day usage. The electric that I have cuts much more than "a small limb a couple of times a year". I would be willing to bet that if you and I cut down a small tree with say a 10 diameter trunk, that you probably would not finish far ahead of me. Many more larger trees and I give you the nod. I think you vastly under estimate what an electric can do if you believe that they are only good for a small limb a couple of times a year. I have owned both and in my yard I would choose electric over gas if both were sitting on my work bench and ready to go. Out in the woods felling trees all day long the gas would be an obvious choice. I suppose it is a lot like Festool of Fein. Unless you are making money or specifically have to have the tool it is hard to actually justify the expense. Then some simply want more than they actually need, and that is OK too. I live in a log home, so I own an electric chainsaw (not one of my Stihls) - saves on the fumes, etc. (When you remodel; a log home, a chainsaw is your tool of choice). That kind of use though is not what 99% of people think about when they thinki about chainsaw use. |

Anything over 100 is AKI You are confused here. There are several methods of calculating octane rating, the two most common being the "research method" and the "motor method". They work the same way, you run the fuel being tested in a special motor which has a variable compression ratio, and compare the point where preignition starts to the point where it starts with a particular isomer of heptane (defined as zero octane rating) and a particular isomer of octane (defined as 100 octane rating). It's entirely possible for a fuel to accomdate a higher compression ratio than the octane standard, in which case it's octane rating is proportionally greater than 100 (conceptually it's also possible for a fuel to not reach the compression ratio of the heptane standard, in which case it would have an octane rating less than zero). Now, in the UK and Europe, they use the research method exclusively. Their octane ratings are always RON (and they have no such thing as an antiknock index). In North America they take the average of the research method and the motor method, and call the result the "pump octane rating". You'll see this on gas pumps: (R + M)/2. (there are exceptions in the US - racing fuel is often specified by RON, and av-gas is specified by MON). For simplicity, rather than say "the average of the research method and the motor method", (R + M)/2 has also come to be known as the antiknock index, or AKI. It's just another term for octane rating. John I understand how octane is determined - and since there is no such thing as more than 100% iso-octane to put in the test mix, 100 octane is as high, technically, as an "octane rating" can go. From 100 on up it is "technically" an Anti Knock Index. AKI can also be used below 100.RM/2 is used for automotive motor fuel in North America - but not for Aviation Gas. I remember this being taght by the petroleum engineers from Texaco, Imperial and Shell when I worked for garages that sold those 3 brands of fuel "way back in the day" between 1968 and 1983. They said although often refered to as the "octane rating" anything over 100 is technically the AntiKnock Index, which in Noth America is generally referred to as "road octane" or "R+M/2" or "pump octane" while elsewhere in the world it is generally ROM - straight "research octane" Octane sensitivity has to do with the difference between research and motor octanes. Motor Octane is also sometimes (mistakenly) referred to as "rich" octane and is the measure of anti-knock qualities under sustained high load, (accelleration at low RPM) while research octane is sometimes referred to as "lean" octane - the measure of antiknock qualities under typical mild driving.(high rpm low load) They call it sensitivity because it indicates hpw sensitive the fuel is to varying conditions of tempwrature and load.. Sensitivity of most automotive gasoline in North America is generally about 10 points. In europe recently the sensitivity has been higher, (20 points and more), meaning some fuels (under 105RON)do not meet the required 85? minimum MON for European regulations. Lean and Rich octane ratings are used to rate aviation fuel.. They are similar to the RON and MON , in that rich mixtures are used under high power settings, and lean under lower power settings. The "sensitivity" of Avgas is generally closer to 30 points (100-130 for instance for 100LL regular avgas) Lean rating in AvGas is always lower than rich rating, just as MON is always lower than RON in Mogas. It is a combination of actual differences in the knock resistance of the fuel and differences in the measurement protocol that contribute to tne higher "sensitivity" of AvGas. The AvGas "lean octane"number is not necessarilly the same as the RON number would be for the same fuel, but it is close. |

A gas tool is a little different, IMO, though. I'd want to make sure I had use for it several times a year (maintenance and all). I have a gas power-washer that was probably a bad idea to buy. I don't use it enough. |
