Accidently put $10 of united ethanol 85% in my car.
Will it be okay if I fill the rest of the tank up with regular fuel or do I need to get my tank drained?
Yes I fucked up.
1999 wrx, mostly stock with aftermarket exhaust but I did go to buy an sti ecu second hand and the guy looked over my car and said he thinks I have an sti ecu already and upgraded injectors.
Tried to google my problem but all the different percentages and ratings gave me a headache.
I have rac roadside assistance.

Thanks
