I ran that stuff threw 2day. Put some in the BB line, crankcase, gas and sprayed some deep crep in the throttle body. Feels good throttle opens up alittle nicer, better mid range. I didnt change the oil yet or plugs but I have check engine light and ATTS light. Any ideas ?

 

Your check engine light is probably on cause of your O2 sensor. Its happens all the time when I run that stuff through. It'll go off eventually, so you have nothing to worry about

 

Change your oil asap.
