After run oil - Which one to use?

I am a newbie. Once I am done flying. I make sure sure I burn all the fuel
in the engine and then use a good amount of after run oil. I find commercial
after run oil too expensive at $2+ for a few ounces.

I have been told that several alternatives can be used:
Automatictransmission oil, Marvel air tool oil, and Starret tool and
instrument oil.

What should I use?

I have an OS .46 engine.

ATF and most any air tool oil will work fine. You need more than a few
drops in the glow plug hole for it to work. a half teaspoon ful in the carb
and let it run into the crankcase then spin the prop a few times with the
starter.

Denis --

Noted engine Guru C. F. Lee has for years recommended the use of Marvel
Air Tool Oil as an after-run. He also suggests a 50/50 mix of MATO and Auto
Trans Fluid (ATF) for long term storage. However, most important of all is
to run your engine dry at the end of the session before the after-run.

Re: After run oil - Which one to use?

Read the label on the fuel you are using. Omega/Cool Power now
recommend that NO aftger-run oil be used because their fuels contain
enough lubricants to sufficiently coat the important parts. I stopped
usinf after-run during the season - I normally fly once a week - and I
have noticed that the engine runs-up faster when cold and doesn't smoke
like crazy when first started for the day.
I do, however still use some after-run if I know it will be sitting for
an extended period, generally more than two weeks.

Marvel is a cost effective choice. Buy it at Pep Boys or other auto parts
store for maybe $13 - $14 a half gallon. Smaller containers are available,
but if you fly a lot, the half gallon is a better choice from a cost
standpoint.

I use Marvel Air Tool Oil. Don't use it in a YS unless it is
of the synthetic based oil.

Just be sure you use fuel with plenty of castor, 20% of the oil, or
more. Using after run oil that will not mix with our fuel can actually
cause corrosion. Else lube the engine with castor oil after flying.

Leaving unburnt fuel in engines will cause corrosion. It's important to
burn off the fuel at the end of the day, and while the engine is still
warm.

So true.

Running a good quality fuel and burning off excess (glow
engines) at the end of the day actually alleviates the need
for after-run oil for short term storage. I don't bother
with after-run oil unless it is going to be a few months
before I fly again.

Re: After run oil - Which one to use?

don't use it. Never have, never will. I have engines that are 30 years
old....have been in unsealed storage for years, and run just fine. As far as
I'm concerned it's much ado about nothing.

Yes, do burn of the fuel at the end of the day. Still a small amount
of fuel will remain in the crankcase. Sometimes I forget to burn off
the fuel, no problems from that, but it is possible for the fuel to
soak up moisture.

Re: After run oil - Which one to use?

I don't think anyone can prove that there is any fuel left in the crankcase
of an engine that was shut off when hot. The alcohol and nitro both will be
evaporated out. The only fuel left in the engine will be in the carb.

I should have said "may remain in the crancase" instead of "will remain
in the crankcase". If there is fuel in the carb it could well drip
into the crank case. Fuel can remain in the crankcase, especially on
cold days. I do not think the moisture will cause corrosion if you are
using an oil that will disolve in the fuel and any moisture it may
contain.
