I have decided to change to premium petrol for my car. Is this OK for 2
stroke garden equipment, or should I always make sure I use the standard
petrol?

Even premium fuel is unleaded these days. Your garden equipment may not
have liked leaded petrol, but there's no danger of that - and premium
will be fine.

Why are you using premium petrol in your car? If it's designed to work
ok on standard unleaded, there's no particular advantage in using premium.

Which? did a report a few years back which claimed to prove that as long
as your car had an ECU which could tune/detune the engine to match the
fuel used, you could get as good or better bangs per buck from Premium as
you could from Regular. That is, if you up the efficiency of the engine by
using better fuel then you get a better MPG. This does, of course, depend
on your mix of driving conditions and style. Also on the current
difference in price between the two grades.

I was always a little sceptical, and anyway my car has adequate power
running on Regular. I don't track the MPG anyway - however it might be
interesting to try running the diesel camper on Premium diesel as I do
track the MPG on that.

I just tried to locate this but only found one from 2008 was a reference
to Which Car which said the so called "Super Fuels" were a waste of money.

http://www.which.co.uk/news/2008/09/...of-money-says-
which-157038/

So, purely for interest, why are you changing to Premium?

Also noted that their costings of the benefits of paying more for a diesel
car in terms of saving fuel costs in the long term were based on diesel
costing significantly more than petrol. So well out of date now and also
doesn't include the latest high efficiency supercharged small petrol
engines.


For your original question - it will do it no harm, but as my late father
used to say "It's like feeding strawberries to a donkey".

I presume you want to use the same petrol can to carry as a spare in the
car and also use to top up the fuel bottle of 2 stroke mix for the garden
machinery?

Otherwise, why would you?


Cheers

In my engineering experience, that is basically correct. The advantage
of using a premium fuel, in a well-sorted engine, is that it can release
more power from the engine than Regular petrol, if the ECU can work
with it. So it's useful for racing drivers or those with a lead foot,
but will do nothing to increase the MPG of Joe Public. Depending on the
camshaft profiles etc, there may be no advantage at all.
It might have extra additives, and therefore run a cleaner engine, but
in general there is a greater difference between the fuel mixes of any
one supplier for summer and winter, than between the mixes of two
different suppliers during the same season.
I have a simple spreadsheet that tracks my mpg. It is also useful as a
way to record prices. I just fill in a few blanks from each petrol
receipt, and it calculates the rest.

The engine in our pretty bog standard (petrol) car has two separate
knock sensors and variable valve timing, it does indeed return better
MPG on "premium" fuel than it does on "supermarket value" fuel.
When we lasted used "cheap" fuel the difference was in the order or
27MPG for "supermarket" fuel and 33MPG for the "performance" stuff.
Averaged over a full tank on each.
Given that, we didn't bother again and just run the "premium" stuff.

Of course, driving style has far more bearing and I guess if we tried
again, the result may be different.

Petrol is governed by Government standards, of course, but the fuel
supplied is going to be the minimum required to meet that standard and
won't have any of the additives* which "branded" fuel may contain.

*Or, indeed in the case of diesel, having more additives than may be
helpful for modern CRd engines...

I am a fan of Honest John. He maintains that supermarket fuel is exactly
the same as its equivalent from elsewhere. Is is subject to stringent
test by the authorities. He also reckons that premium is well worth the
money, both for its effect on the engine and consumption

and read as much discussion as you want to.

I tried BP premium Diesel (or what ever its real name is) for 3 tank fulls.
Absolutely no difference in fuel consumption.

I have an acquaintance (brother of work colleague) who is a tanker
driver. What he says pretty much sums up what is said elsewhere, there
is a base quality fuel which is the same for everyone. The difference
being different blends and additives for "premium" applications.

Apart from documented cases involving biodiesel, "supermarket" fuel
shouldn't in itself cause any problems.
Unless there are problems on site, but any garage could have that.

It probably makes no difference, but I believe that most 95 octane
regular unleaded petrol in the UK contains 5% (or is it 10%?) ethanol.
I think most super unleadeds are ethanol free.

Ethanol has a lower energy than petrol, which probably makes no
difference in a mower, and it can absorb a bit of water.

Since - in any given region of the country - it all comes out of the same
tank at the same regional depot fed from the same pipes from the same

Ooh, yes. Forgot. The driver adds a bucket of damn-near-homeopathic-

has your fuel gauge been buggered up by supermarket petrol as
well ? .....

Woss wrong with supermarket fuel? We never buy anything else
(diesel C4).

buggered up my old merc fuel gauge.....few tanks of shell and BP
premium sorted it out ......

and where do you think the supermarkets get their fuel? some
backstreet arab trader?


most only do 95 oct .....

nothing to do with "supermarket fuel" then - you put the wrong octane
stuff in.


no I put in the cheapest with no additives...v power sorted the problem
....never seen a tesco that had anything other than basic 95 unleaded ...

I know Sainsbury's diesel has addatives. If you must use a cheap
supermarket don't assume all others are the same.


think they only do 95 ron basic petrol .....

There are certainly 3 different fuels at the Sainsbury's that I use. One is
diesel. so presumably the other two are different grades of petrol

filthy smoke,

I've seen far more smoke out of petrol cars than diesel ones. MOT tests do
keep the smoke down. Lorries, that's another story.


dual mass flywheels, turbos to get any performance,
particulate filters etc etc....

What's wrong with a turbo?

Petrol is governed by Government standards, of course, but the fuel
supplied is going to be the minimum required to meet that standard and
won't have any of the additives* which "branded" fuel may contain.

*Or, indeed in the case of diesel, having more additives than may be
helpful for modern CRd engines...

Since - in any given region of the country - it all comes out of the same
tank at the same regional depot fed from the same pipes from the same
handful of national refineries...

Ooh, yes. Forgot. The driver adds a bucket of damn-near-homeopathic-
quantity brand-specific additives.

Roughly what percentage of the UK vehicle fleet fills up at supermarkets?

about 45%

I do see filthy smoke taxis and other small commercial vehicles from
time to time, I assume it's because they haven't bothered to maintain
them although how they get away with that vis-a-vis the MOT is a good
question.

I just had my particulate filter changed at 75k miles.

you don't need to do that on a petrol...and don't get me started on rubber
cam belt diesels .......

It probably makes no difference, but I believe that most 95 octane
regular unleaded petrol in the UK contains 5% (or is it 10%?) ethanol.

E5 - 5%. E10 95 is becoming available, but it'll have to be clearly
labelled, and E5 95 will remain the default "protection grade".

I think most super unleadeds are ethanol free.

Nope, they're all E5, too.

of tank ...

Says more about your Merc then i think.

I've only ever used standard fuel (petrol or diesel) supermarkets, oil
company garages where ever, never had fuel gaugae problems on any of our
cars
