Default Premix at the pump

The next time I take my FC to the pump, I plan on pouring in some 2-stroke premix. About how much premix should I add per tank? What type of premix do you guys use?

I was thinking of using Royal Purple 10W30 and premix once spring (racing season) comes around, but I'm sticking with 10W30 conventional for the winter.

Stock S4 N/A 13B. The oil metering pump is in place and working.

every time you roll over a couple of gallons, add a couple of ounces. 1 gallon of gas/1 ounce of oil is the rule of thumb.

why do you need to premix if you still have the OMP?

If you have the OMP still working, 3-5 oz per TANK, is all you really need

No you don't, Amsoil Interceptor FTW!!!

I just got done researching both of these...while Idemitsu is a very very good choice, Amsoil uses more cleaners and makes your engine nice, shiny, and almost carbon free.

+1, 1oz per 1 Gallon is the measurement for non OMP vehicles.

Keep in mind guys - as it always in when premixing anything (cars, bikes, lawnmowers, etc) you add the oil to the tank FIRST and then add the gas... otherwise it won't mix evenly. You use the pressure from the gas pump to slosh the oil around and mix properly.

If you are using the stock OMP you really wont need more than 3 to 5oz like others have mentioned. Going more than 100:1 is a bit much....

I use the Wal-Mart cheap stuff. Let's be honest here, unless you're running some obscene hp (or something...), I really really doubt you could tell the difference after 100,000 miles between mine and the stuff that costs 5x as much.

Not as its running no, you notice if your the one doing your own rebuilds. Your parts come out clean as opposed to carbon coated.

Though, if you could collect all that carbon and make Apex Seals out of them...

If it has TCW3 on it, I try it. Haven't found my favorite yet, however.

Probably because there's hardly any difference.
