nettoie en profondeur

effectue un excellent nettoyage des injecteurs

Cleans very well and last a long time

Worked great, up'd my mileage about 2.4 GPM

Vue la différence wow

This product improved my gas mileage by at least 2-3mpg in my Tacoma on the interstate. It seems to last fir several months too.

I do notice a few MPG difference when using this regularly. Minimal investment for keeping your fuel system clean and running in good order. Great product.

Had a little hesitation in my wife’s van, put this stuff in it and it cleaned it right up. Picked up a few miles a gallon also. It will pay for it self

My car was idling a little rough, after a tank of gas with PI it is idling smooth again.

I've been using only Amsoil products since 2000 because they are the best.

I say it all the time... I trust in the testing on Amsoil products and against Amsoil products that Amsoil almost comes out ahead of the rest in almost every category of testing. So, I'll be using Amsoil as long as I'm alive...

This is a great product, the long drain interval is awesome! I’ve been using amsoil stuff for over 20 years, and I couldn’t be happier! Thanks for great products!

I have only used this product 1 time so far. I did not notice much of a difference at first but by time I had used 1/2 tank of fuel I noticed my vehicle more responsive when I stepped on the accelerator and by time I had burnt 3/4 tank of fuel my mileage become notibily improved

Run this in all of the vehicles. Never had any issues.

I used PI for the first time after an oil/filter change at 107k. I was amazed that I actually could feel the power and the fact that my gas mileage increased by 10%. This stuff really works.!!!

I have used this additive since Jan. 2015… Clean smooth performance, and improved optimal mpg😊👍

I have been using all AMSOIL products for past 20 years. I have 3 cars with over 400000KM … still going strong. Dependent on AMSOIL.

MPG’s went up so that means it worked. Very happy with this product, will be buying more soon.

I won't change your oil if you don't use this product at least once a year, preferably before every oil change. It only makes sense to clean your fuel system and everything else for that matter before changing your oil and filter. Dirty fuel injectors contaminate engine oil. This product really works and I have photos to prove it. I recently removed the intake manifold on my friends 2005 BMW 325i with over 300000 km's on it with the check engine light on forever, I couldn't believe how clean the intake valves were that a photo was required, he used P.I. before every oil change for over 5 years.

I COULD NOT TELL THE DIFFERENCE IN PERFORMANCE AFTER USING THIS PRODUCT. I WILL USE IT AGAIN.
