I wouldn't run a 50 wt oil in a splash system that oil needs to find its way there its not being pumped to key areas like a late model with a dry sump I run 0w20 I wouldn't go higher than a. 30wt.I've been running valvoline 20w-50 in mine, I figure it's what many guys run in their high compression built stock car =late model engines, why not in a high compression push rod style kart engine?
FHS 62 R is in my opinion the best oil for an open engine. Without any question. Changing any Oil in a open after every trip to the grid is important. Idling and parade laps are your enemy!FHS 62R
Briggs 4T
Those are both good options. More people will come and chime in
I think it was probably on Facebook, can't honestly remember...somebody made a side cover out of thick clear plastic, so you could see what is actually going on inside a 4cycle ohv engine when at high rpms, I'm no expert, but from what I remember seeing and kinda knowing the inside of a motor case, I can't believe there is any issue with the dipper not splashing oil around all needed areas, but again, I'm no expert....
I raced for years with cooking grade peanut oil and additives in methanol powered flathead engines. No failures, but a lot of work with minimal financial benefits.62r or a bean based Castor. These should be the only 2 considered for open 4cycle racing.
Secrete Sause? Which one should I order hot or mild?
Lol i agree with the thinking.i was thinking about schaeffers.they run it in 3000 hp drag motors.air cooled engines run same internals temps as a water cooled motorI've been running valvoline 20w-50 in mine, I figure it's what many guys run in their high compression built stock car =late model engines, why not in a high compression push rod style kart engine?
