From what my dealership parts guy told me, the "new" TEC is EPA compliant. Comes in a plastic bottle. I got the last three cans of the old stuff, and it came in a metal can. Ive used the new stuff pouring straight into the TB on my 5.7 truck motor, with no bad effects. Seemed to work just as good.
Sea Foam should be just about the same, as Eric said.:smile:
