"Spivey recommends using gasoline with an 89 or 93 octane rating, if you
can afford it. The fuel is slicker, which means it won't hang around on
your engine valves and other internal parts, eating away at the rubber."

Is this true?

I have no lab tests or anything. But, that sounds like nonsense, to me.
"Valves" such as intake valves are exposed only air and gas vapor. Exhaust
valves, vapors, and, well, exhaust.

Any fuel line parts are in contact with fuel, full time.

Hi,
First, what is Octane value? Why 89 or 93? 91 won't do? What kinda talk
is that? I use Shell 91 always, some times 94 blended with Ethanol.
Owner's manual always mention about proper gas to use for the engine.

89-octane is also known as "Regular". This is the cheapest grade your gas
station sells.
93-octane is also known as "Premium". This is usually the most expensive
grade your station sells.
Usually there's also a mid-grade that's 91-octane.

Next time you fill up, take a look at the stickers on the pump near the
buttons where you select the grade you want. Also, your engine's valves do
not have any rubber on them.

Octane has zero to do with how "slick' the gas is. Rubber-deterioration has
to do with the ETHANOL in the gas. All gasoline engines since about 1975
are rated for up to 10% ethanol. This means that the polymers present in
the fuel system are able to withstand the damaging effects of alcohols up
to a 10% concentration.

Using too much ethanol in a small engine might burn the engine out.
That's what a chain saw repairman for an authorized Stihl dealer and
repair centre told me. He said if you can't avoid ethanol based
gasoline, get the highest octane available for your small engine because
it'll help cut down on pre-ignition

Mower? I thought we were talking about cars. I'm so, totally terrified. Teh
author claims it should be carried out (not done, it's too simple to "done")
by experienced mechanic? And, to think I've risked my life so many times,
working teh lawn mower? I'm amazed to be alive. I'm so grateful, God! I'll
even go to church tomorrow! [sarcasm off, now]

I'll have to tell them to change their stickers, immediately.
I've been to several gas stations this week, and they
mistakenly had 87 octane for sale. I'll tell them to correct
the labels, imediately. After all, invalid at example dot

93-octane would be a super-premium, and is not offered by all companies.

In any case, as I said before, octane has nothing to do with "slickness",

Only way it would make sense is if the 89 is not ethanol added fuel.

Why's that?- Hide quoted text -

- Show quoted text -

Because small engines don't have a high enough compression ratio for
pre-ignition to be a problem. If they did, you'd see a lot of
recommendations from
small engine manufacturers to use higher octane gasoline in say your
lawn mower. I've never seen one that calls for anything higher
octane
than regular.

As for burning the engine out, I've had a lot of small engines over
the years in a variety of typical applications. I've yet to see one
"burned out". In my experience, as long as you change to oil,
make sure it has oil, etc., the end of life has always come due to
some other failure. Latest is my Honda self-propelled mower, where
the tranny died. Given the age and cost for a new one, decided
it wasn't worth it. Engine? It's still running fine on regular
unleaded.

Ethanol actually runs cooler, thus the reason for less gas mileage out
of it than with gasoline. Ethanol raises the octane rating. The worst
thing about ethanol is the fact that it absorbs water (after a great
period of time) and it's effect on rubber over a great period of time.

Ethanol raises the octane rating *because* it burns cooler. Modern
(automobile) fuel systems are sealed so there isn't a lot of water to be
absorbed. The fuel delivery chain has been upgraded over the last few decades
so water isn't an issue there, either. Ethanol won't harm the "rubbers" used
in fuel systems, though methanol will. The problem with ethanol is that it
*does* burn cooler so has less energy content (lowers gas mileage).
