Oil Usage - Need some expert knowledge.

Is there a chart out there that tells the mixing ratio of oil to gas when using the oil pump? Trying to find out what the ratio is at idle and then at WOT.

I am going premix and I know that the recommended ratio is 40:1 gas to oil. I want to know how the 40:1 premix ratio relates to oil pump ratios. Thanks for your time.

The rate of oil use varies, as the rpm's increase. There is no formula to give specific ratio at any given RPM. The only thing you can do if your going to run pre-mix is just go to 40:1. That way it won't lean out at high rpm but could foul spark plugs at idle. That's why you should use the oem oil pump.

Yeah I am thinking about just keeping the oil pump, may not be worth going premix.

Just do some maintenance and use the pump. Premix will cost you a lot more.
