the 2 stroke oil i put in says meets tcw standard I guess it is alright car still runs fine 1/4 tank later feels smoother and puls hard like ****. Next time I will get the good stuff.

4oz for a full tank is enought for street driving, I double it when i go to the track when the engine is going rev high all day.

Is it possible that having way too rich pre-mix mixture could cause a freshly built large streetport s4 turbo motor (stock injectors) to not idle? i.e. too much oil, not enough fuel? Seriously, I think I've got something around a 200:1 ratio in the tank, lol. Since I was gonna be starting the motor for the first time, I wanted to put a good amount of oil in the tank just to be safe, so I dumped 16oz. in there.... and then I realized I only had half a tank of gas... https://www.nopistons.com/forums/pub...DIR#>/wink.png

put more gas in?

with 8 gal of gas and 16 oz of oil you have a 64:1 ratio. Fill the tank with gas.

Probably couldn't hurt, lol. https://www.nopistons.com/forums/pub...DIR#>/wink.png
