My experience is with R/C boat engines, so perhaps there is a disconnect here. However, every racer I have ever spoken with or asked advice from has used some sort of after run oil.

I am using the term after run oil generically. I usually use some mix of Marvel Mystery Oil and Prather After Run Oil.

Do NOT use WD-40 on the inside of your engine! After Run will absorb the water in the engine, not just displace it.

Charles - Oil can get gummy and make the engine hard to start, and most after-run oils will ruin the o-rings in a carburetor. Some fuels simply recommend not using an after-run oil.

Traxxas knows what they're talking about and if they recommend WD-40, I'd use that until your warranty is up. I personally use the oil used in Trinity's fuel for after-run..hehe.

I like wd-40 to clean the chassis and make shiny. But not in my motor. Marvel mystery oil does great there. And for nuts bolts, bearings, whatever. Like the post above says, take an old sleeve or something, put it in a container and liberally spray it with wd-40 and let it sit. Gels up and you have to clean everything again. I had my motor apart and all cleaned one day. Put it in a zip lock doused with wd-40. Next day when I want to assemle, the stuff is nasty.

Also don't let parts sit in isopropl alcohol for to long. They rust up real fast.

I tell ya, you should try the PB Blaster stuff. It WILL NOT GUM UP if left sit for a LONG period of time. It works great as after run oil.

Marvel Mystery Oil and tranny fluid like you say both work well.

I've been using it for a few years now. I can store my engines for months and they still are freed up and not all sticky feeling when I check them.
It also helps restore rubber seals and o-rings and DOES NOT evaporate, it's a great moisture displacement as well. Another thing is, it has a additive that bonds to the metal and allows it to help seal worn engines.

I use it to beak-in my engines as well. What I do is spray a shot or two in the tank before I fuel it up then start my beak-in proccess. Doesn't hurt a thing and helps the engine to last longer.
