I put Amsoil in everything I have, from my cars , truck, motorcycles, dirt bike, Boat, side by side, ATV and yard equipment. They even sell gun oil!

I have used this product in both of our daily drivers. They idle smoother and the gas mileage got a little better in both vehicles as well.

been using this product since 2004. work well and will keep using it

I use this every time we make a trip to other states. I only need one for a tank. I got about 44MPG!!! at one point during my trip. I averaged 40Mpg there and back about 850 mile trip one-way. I'm still getting great gas mileage for close to a moth after putting it in one tank. I highly recommend this product!!!

I use PI every couple of tanks of gas and haven’t had any problems.

This stuff really works. It really cleans the fuel system.

Great product. I’ve used it every 5,000 miles on all my cars over the last 3 years.

This product helped attribute to fantastic idling and MPG just like the upper cylinder lubricant. I like to put this product in when I change my oil and go on a long road trip. The deep heat cycle of the engine helps clean the carbon deposits in conjunction with P.I. Improver. These products are fantastic and I will continue to buy them.

excellent product,outperforms gm oil

This is no snake oil like the rest of them on the market. This one works great at cleaning the injectors/pumps/combustion chamber etc. I saw my mpg go up 3 points after using this 3 times. From then on ive been averaging 29-31mpg constantly. Before it was 25-26mpg.

I would definitely recommend this product. I definitely felt the difference.

this is gonna be short and sweet. I love all of your products. just changed over to your diesel oil for my 2016 ram cummins.now I want to see if you guys carry fuel filters for it. thanks for the great products.

See the story in the previous product review.

Great product but bottle needs better functioning lid. Very difficult to remove

this stuff seems to make a difference, and its good to have a product you can trust

Great product!!!

The first bottle will make a noted change and one every few months will keep it running at peek. Makes a huge change in small engine, and all types of non road gasoline engines

Always improves my Tundras gas mileage.

As the Title says, this is an Absolute Essential part of any Vehicles standard Maintenance Routine, as Crucial as changing the Engine Oil & Filter but this couldn’t get any easier! This is as simple as it gets when it comes to Routine Maintenance and as easy as pumping gas! Once every 5,000 to 7,500 Miles simply pour a bottle of Performance Improver into a near EMPTY Tank and fill-up good for up to 25 gallons! Amsoil’s Performance Improver does the Tough Job - Cleaning the inside of your Engine and Fuel System, from the Fuel Pump to the Injectors - The Valves to the Piston Head and Combustion Chamber! I highly Recommend this Gas Additive to all my friends, family, and anyone trying to keep their Engine running at it’s BEST, in a “Like-New” Condition, no matter if your Engine is Brand New with only 10,000 Miles OR has worked hard for over 200,000 - Whatever the case - this Additive is a MUST!!

I add one bottle every 4,000 mi to my truck and suv to keep things running smoothly
