Cole Posted March 12, 2009 Share Posted March 12, 2009 I am planning on just premixing my 72 R5 because I can't find a part for the oil injection system that I need. I was just wondering if anyone knew the mix ratio for it? How much oil per gallon of gas? Link to comment Share on other sites More sharing options...

I was just wondering if anyone knew the mix ratio for it? How much oil per gallon of gas? 32:1, 4 ounces to 1 gallon. Link to comment Share on other sites More sharing options...
