GMK advertises theirs as silicone safe.

ARO is not needed when you store your car properly and use a good fuel. Odonnels is just fine, so as long as you don't leave your car in the garage or in your truck where it will see temperature deviations and condense water inside you wont ever need aro.

I have been using GMK's After Life oil for a year and it has been awesome. I have used it in 3 or 4 different engines, and never had any problems.

People have had all kinds of experiences with not using ARO with certain fuels but leaving any unburnt alcohol in an engine without ARO is a big no-no. I have seen especially bad rusting with O'Donnell's (see what I mean..) and the O'Donnell's racers/reps that I race with would not recommend not using ARO with their fuel because it's designed to run well, not to be used as a preservative. Bottom line, use ARO, there's no downside to it.

As for the silicone thing, plain ol' mineral oil is fine and you can get a quart for what 2 oz. will of branded ARO will cost you.

None of my engines have the silicone so I use Prestone marine fogging oil. It's in an aerosol spray can so I zip-tie a piece of fuel tubing onto the tube and shoot it right into the carb while spinning the motor on the starter box.

general rule for filled crank:


red ARO NO GOOD

clear ARO GOOD

Never heard that before. If I ever do use any after run I use Marvel Mystery Oil.

What about that new Losi blue stuff? It's clear but it's blue.

Intresting topic,

There are many reasons why one should use ARO, most are within reason and probably would hurt in doing so. I take into account where I live. I am up in the High desert of Nv. where air is thin and the humidity is very low. Most things don't seem to rust or corrode as fast as they would in a much higher Humidity climate. Helps me to decide how often to use ARO. If I run evry week, I won't ARO my motors after every run, maybe every other run. At the end of the season I do, more for winter storage. Seems to work so far.

If your storing for more then 4-5 month's i would recommend a complete tear down and store the motor in parts....assemble when you want to run again...it'll be a lot better for the motor in the end.

Yamalube engine fogging oil is safe for filled cranks. Been ususing it for awhile on my Speed motor.

More importantly is ALWAYS run the fuel out of your motor completely at the end of a days use. Burn off everything leaving only the oil residue behind is more important than using an after run oil IMO

I've seen marvel eat the fill, I use it on all my non filled engines though...


Losi blue, hmmm, never seen it, I tend to stick to engine company products for engines

So if I used the red hobico ARO in an OS speed 1 time did I kill it?
