I just noticed today i was going on the expressway at about 100-120 mph and i noticed alot of white smoke.. Just when i floored it though..

Car doesnt smoke when i turn it on or when im cruising.. Just at high mph..

Any Ideas? I accidentally put some cheap gas in it yesterday i pressed the wrong button.. But isnt white smoke oil being burned?

I also just put in 3.42s speedometer is off but I dont think that has any thing to do with this..

Thanks

 

White smoke means water getting burned. Blue means oil. Black means excessive gas.

 

I think it was white.. I have a tinted rear window so it could of been blueish but im not sure..

Oil color is fine.. Doesnt look like chocolate ..
