I actually used PP in my old car and went to Valvoline Synpower where mileage went down. I went back to PP and it came back to where it was before. This UNSCIENTIFIC example shows me that OILS do matter for certain engines. Would either of the above give me anything in my F150? OR would I have to go to a Royal Purple or Amsoil to maybe see a difference?----VenzaTRD
I have a 5400 lb Nissan Pathfinder with 3.5L V6 that got only 13-15mpg city driving in hilly Worcester, MA. Bought a 300ml can of LubroMoly MoS2 Anti-Friction Engine Treatment at NAPA for $4.29, part no. 2009. Made in Germany by Liqui Moly GMBH.
Put it in and filled up.
Pathy has M1 5W-40 Truck/Suv in it. Since adding the Moly, it spins faster when cold, is quieter, peppier, rolls further in gear with foot off the gas, feels like I changed the oil and plugs and got a tank of 100% ethyl but its the same E10 from a nearby Mobil Station with 6 month oil and 72,000 mi plugs.
Trip odometer reached 300 miles on the tankful for the very first time in the truck's life and it turned in 307mi/18gal=17.05 mpg which is a vehicle record for city mileage. It done as high as 21 mpg at a steady 65mph on a freeway, but never hit 17 in the city before. I should add that the truck has not seen an energy conserving oil in the last 4 oil changes and maybe that skewed results.
Lubri Moly's MoS2 lubricants are very highly regarded by performance car enthusiasts with Mercedes, Volvo, Audi, Porsche and VW with turbo. From what I've read,.3uM sized MoS2 particles pass right through car filters, won't precipitate out, and protect high wear areas like connecting rod bearings and camshaft followers even better than ZDDP. MoS2 survives combustion temperatures and sticks to metal like it was welded.

I'd give it a try. Its going in ALL the cars in this family now. Best $5 I've spent in years, no kidding. Right up there with Conti Extreme Contacts and Purolator Pure One oil filters.
Nano lubricants rock!
What year is your Pathfinder? The curb weight for a 2008 is 4,684lbs......
