Sounds kinda fishy to me. First, the only endorsement is from the OCC group, which in my opinion did more harm than good (watch the 30 sec video - Paul Sr. should never be allowed to speak publicly again, bless his heart!).
Second, it hasn't been picked up by any parts suppliers- basically only available online??
Third, it has some mighty big claims: Reduces fuel consumption by 15%??
So.....If you have a 30 gal tank @15 mpg, you'd have a range of 450 miles.
An increase of 15% would mean you'd have an extra 4.5 gallons left over for the same distance traveled, which would increase your range to 517.5 miles and would come out to be 17.25 mpg... That's a little hard to believe- not saying it isn't possible, but coming from a completely unknown source with no credible backing??? I don't think I'm pouring it in my baby!
Just my
