I have an emissions test coming soon and aside from running a tank of hi test through it, what are good cleaners to add to tank?

I looked up seafoam, but I'd prefer something in the tank just for simplicity sakes, also read some people having problems with seafoam.

What has worked well for people?

Thanks

 

not a cleaner really more of a lubricant, I use Lucas.

 

Best thing for emissions is probably going to be RXP.

 

ive ran seafoam and lucas in my tank before

 

Remember, you need several duty cycles to eliminate any DTC and emission tests that have been set. A few stop and goes and several highway trips usually helps.

 

i use lucas upper cylinder lubricant..

 

What is everyone opinion on z Max??? Since we r talking about additives lol

 

E85 but u will need to change filter after the first tank!

 

Sweet. I'll check out my autozone or whatever its called here.

Also, I got a new exhaust on my truck, stupid thing loosened up. Now I gotta get it retightened. LAME.

 

seafoam. it can be used in your gas tank, your top end thorugh the intake and through your crank case before an oil change.
