So I have a Rotax 503 two stroke. It requires a 50:1 ratio of oil gas mix.

My question is, how many ounces of oil do I need to add to 5 gallons of gasoline to make that mix?

I thought I looked it up once and it was around 2 ounces for a gallon. At that ratio it would simply be 10 ounces for 5 gallons. But I have been told this needs to be exact, and not an approximation otherwise the carbs will need to be re-calibrated.

Anyone know the exact amount for 5 gallons?
