Methanol Oil???

[TotalWreakageLive]

What oil should i sue for my methanol go kart? What do y'all run? Where can i buy? Thank you in advance

Go with a decent synthetic, and expect to change it regularly. From what I remember in dragsters, we changed every run because it would wash down pretty bad.

I think he is talking about a 2 stroke engine and not a 4 stroke. I was waiting for Anderkart to chime in because he used to race them.

Methanol 2 stroke? Seriously? That sounds fun!
With as violent as methanol is, do they live long?

Yes, they can last a season. Anderkart can explain more.

I used Royal Purple brand strait 40 weight in my Methional fueled, 357cc. Tecumseh Star racing engines, just because it was recommended by the shop that blueprinted my engines.

I used to change the oil after every night of racing, because the extremely rich, carburetor jetting mixture required for methional fuel tended to wash down past the rings and pollute the oil. I used to drain the old oil out at the track right after my final race, when the engine was still warm.

I don't know what brand (or weight) of oil is best for your methanol engine, but you could research older threads & post your own thread at a racekart forum called bobs4cycle.com and probably get some really good advice from guys that currently race engines just like yours...

My Tecumseh Star engines were 4 cycle:

Sorry, there are so many different styles of engines hard to keep track.

I'm a die-hard believer in Royal Purple. I use their break-in oil for a straight-gas setup, a 212 running 15+hp., and refill with the same after the break-in period.

If you're talking about a four cycle engine, look for kart racing suppliers. Many of the racing classes require methanol fuel. If you're talking about a two cycle, look for kart racing suppliers. You'll need an oil designed to mix without quickly separating.

Violent? Are you perhaps thinking of nitromethane?

 

[AmishMike]

Yes, sorry. Nitro is brutal, alcohol is the opposite, nice long steady push

 

[Denny]

Actually nitro detonates. That’s why it is called liquid dynamite!

 

[65ShelbyClone]

It can do that and when it does, engine parts end up in the grandstands. It doesn't do that under desirable conditions.

 

[Denny]

Sure it does! Except it does it in a more controlled manor when the timing and mixture are right. When the timing is a little to advanced for the mixture, or a little to retarded for the mixture that things get real bad real fast!

Unfortunately I am talking about a 4 stroke, 2 stroke would be dope though
