Good stuff!
Engine was running a bit off and according to the scan tool I got it was running too lean at mid range for the Fiat 1.4 engine. Put this in half tank (wot work with full tank I tried this before) high octane Shell VPwr E5 fuel then went for a long drive. Filled up with E10 She’ll Fuelsave the leaning out has reduced and is running smoother.

Ran Amsoil PI in our 2018 Infiniti QX 60 which per the specs gets up to 21/27 mpg city/highway. Well either this stuff really helps or our car is an excellent liar. Side note we do run 90 octane non ethanol gas in our cars as well. Update….ran this in my 2014 Lexus IS 250 F Sport. I wanted to see what i would get strictly on the highway. Reset my fuel mileage once i was in the freeway and my destination was 200 miles away. My F Sport is supposed to get 20 mpg city and up to 27 mpg highway. Well by the time i reached my destination my mpg said 29 mpg. That is 2 mpg above the top end of what my car is listed to get. I was impressed. I ran one bottle of Amsoil in a full tank initially. Once that tank got down to less than a quarter of a tank i put one more bottle of Amsoil in and filled up again (i use non ethanol gas only). Performance has been excellent!

Truck ran great

I didn’t see the improvement that others did right away. I used this on my 2016 Odyseey with 150k miles. I plan on trying it on my X3 next.

You never know with these types of products but I do feel it did have an effect on the engine running smoother
