    Correct oil to fuel

    Would the correct amount of oil be 1 1/2 ounces of oil to 1 gallon of fuel for Optimax.Would it be ok to use Pennzoil premium plus for this.

    DFI is different than a standard 2 stroke. So, what are you wanting to do?

    150:1 is the ratio if you're using PREMIUM PLUS in your fuel as mentioned in the FAQ Section. 4.4oz per 5 gallons of fuel, 8.8oz per 10 gallons of fuel.

    That's 0.88oz per gallon.

    I would stick with the Mercury or Quicksilver Premium PLUS for this purpose.
