race oil ?

OK I'm racing my rupp,it has a 293 Sachs, i was talking to other people and they said to use AMSOIL race oil, it in a red jug so i bought it ,i ran it last year didn't notice a difference but it seems a little rich,i was told you can mix it leaner when u use that oil but i mixed it the normal ratio,I'm running 110 octane AV gas and this oil how lean should i go has any one used this stuff

We tried av gas and found it to dry. Locked a couple of Sachs motors up on it. Went to 114 octane Turbo-blue fuel. Have not blown a motor up on this. We use Extreme oil seems to work good for us.

When I run out of Amsoil,I'll be running Extreme by Fowler! rupp838485,have you taken apart any of the engines you have used Extreme oil in?Do they look ok? Are you mixing 50:1? Thanks.

what mix ratio are you guys running, I read the jug on the Amsoil dominater race oil and it say recommended for 50:1 pre mix, but the rupp says 25:1, I no thats pretty fat

I run 50 to 1 as far as mixture. When I refresh my motors they seem to be OK inside. As far as Amsoil the guys that were running it seem to slow down the more laps we run. We think the motors were running hotter. But that is just our opinion.
