I have been informed mixed opinions as for using WD-40 as an After-run Oil.

What do you guys think?

Hi,
I just ordered my first Nitro truck. Its a RTR Savage. I am new to the truck and car thing. But have been flying RC planes for almost 7 years. Everyone has their own opinions, but if I were you I would use after run oil to be on the safe side. I have used it from day one in all my airplane engines and havent had any trouble with them. Just my opinion though, but I am sure you will get some more info and opinions.


Hope that helps some what,[8D]

They serve the same purpose so i dont see why you shouldnt use it. Ive heard from people on here that use it and have no problems with their engines.

I wouldn't use WD-40 in my engine. I know that Traxxas recommends it though and nobody would know Traxxas engines better than Traxxas.

i know some one who used to use wd40 as after run and then had a massive rear engine bearing failiure in there .46 FX

wd-40 is what i use because traxxas says to i have also used after run oil and i see no difference at all. maybe some engines wonts allow it so asking us might not be the best thing. you should just get a hold of the company that makes your engine and ask them. that would be the best thing to do.

wd-40 does the same thing as after run oil. it displaces miosture that can cause corrosion. after run oil does the same thing but it does not have as many other uses. i personally use both but i like the wd40 better because it can be used on so many other things.

As for TRX 2.5 I look at it this way. There is too much liability involved for traxxas to recommend using a product that could potentially ruin the product. Another thing to consider is using WD40 as recommended by Traxxas. It is possible that those people that had problems after using WD40 used too much. WD40 is a "dry" oil and could potentially screw something up if not used in moderation.

Just my $.02

Marvel Mystery Oil is far superior to both after-run oil & WD40. (and it's a lot cheaper!)

WD-40 will not hurt your engine per se. It is a mild lubricant and it does displace moisture. The down side to WD is that it evaporates and film in which it leaves behind is fairly pathetic. Find a door in your house that has a squeaky hinge and spray it. Take note of how long it takes to squeak again (car doors work even better for this experiment).

I do not run after-run oil in my cars/trucks. I run them off and on all year long so they simply don’t sit still long enough to need it. The castor oil already leaves a lubricating film which is fine for weeks at time without any run time. I do, however, run after-run oil in my helis and planes when they are put up for the winter.

The Marvel Mystery Oil is a pretty good choice in my opinion but Household 3-in-1 oil, the same oil I use in my air filters, seems to work the best.

Try the same “squeaky door� experiment with the 3-in-1 oil.

So far the poll states a tie. Anymore opinions?

After run oil is not that expensive.. why would you even take the chance with WD-40?? Spend the 5 more bucks and get something specifically designed for RC engines.

what would be a good after-run oil for me to get at my lhs?

I spray my engines with WD40 after I clean them with carb cleaner but I make sure I use after run oil before I put it back in my rides.

I have been using Marvel Mystery oil for 20 years in my engines with no problems.

Did you guys know that WD-40 stands for "Water Displacement, attempt #40". Just a fun fact.

Actually, I understand that WD-40 isn't even an oil. It's not designed to be a lubricant any more so than water. All it does is displace water.

Yet-another-hobby of mine is woodworking. Getting oil on wood (more specifically silicates) is a disaster when it comes to finishing. However, WD-40 on wood does not affect finishing.

For the hinge example, the reason WD-40 won't keep something from squeeking for very long is that all you are doing initially is loosening the joint. Once the WD-40 evaporates, there's no more lubricant.

I tend to think of WD-40 as more of a solvent than a lubricant. It also makes a great flame thrower [:@]
