ratio

Hey guys! I replaced a 717 engine in my speedster and have a question. I know there is a break in oil to run in 10 gallons of gas in addition to the stock injection system. What is the correct oil ratio????? Don't want to get this wrong as I've got a lot of time and $$ in this project...

I have a 1997 gti that has to take pre mixed fuel, I was told by the seller to use a 32/1 ratio and had a mechanic tell me I should run 50/1. Help me out please!!!! Thanks David
