Good price, however it is not nearly as effective as Chevron Techron that contains PEA. You may also consider Sea Foam or Berryman B-12 Chemtool even though they do not contain PEA. Also consider buying fuel from Top Tier stations. LGB.

I put this into my gas tank about every other fill up and the car actually gets better mileage, however, I have switched to full synthetic oil so that may have helped as well.

While I can’t sit here and say it makes my van run like new I can confirm that it doesn’t run worse. Like fresh prune juice this is supposed to clean out the gunk in the fuel system. I can only assume it did this.
