ok for 32:1 ratio it is 4 ounce per gallon so it would be 4ounces times number of gallons. so 4x5 equals 20 ounces of oil.

32:1 and 40:1 are what most people mix at depending on what kind of oil they run.

32:1 or 40:1 is fine. Typically I make the recommendation that if you banshee motor has stock porting 40:1 is fine. When you get your engine ported, I would switch to 32:1. But there are alot of peeps out there running 40:1 on ported motors....so it really comes down to preference.

I am also a fan of full synthetic or castor based oils to protect the crank bearings.

go down to your local cycle shop and get yourself a measure rite cup. has all the gas to oil ratios in increments for 1 gal, 2.5 gal so on... makes life real easy and use good 2 stroke oil like maxima castor 927 from the same shop.

Most likely you will run 40:1 because it's really easy. If you want all the conversion and math behind it, let me know, I can bore you to death with it, but in a nutshell:

32:1 means 20 ounces in 5 gallons, or 16 ounces in 4 gallons.

40:1 is 16 ounces of oil in 5 gallons. This is really easy because pre-mix oil is often sold in 16 oz. bottles, so you don't even need to measure. Just pour one bottle into 5 gallons of gas.

Depends on the oil... I run about 50:1 in my shee and my RM250 but I use Power Plus. Power Plus is designed to run at 50:1. Actually, I usually pour just a tiny bit more oil in to run a hair richer.
