hey fellas i have a 1985 gsl-se with the 13b motor.it now has a racing beat intake, holley 650 double pumper and a 5gallon fuel cell. i dont plan on using the oil injection pump anymore so i know i need to premix my gas with 2stroke oil to keep my apex seals happy.. my question is how much oil do i put in my 5gallon fuel cell when i refill.. please help me get the correct ratio.thanks

 

5 oz

 

I've read before that the premix ratio is like 128:1 But you might want to do a search for that exact term, "premix ratio" There might be someone with similar modifications who has a more specific ratio.

 

100:1 is what the camel series rx7 ran and what most people like..about 5 - 6 oz per 5 gal should be good

 

Yep, 1 Oz per gallon is the generally accepted amount.
