Improved throttle response and M.P.G.

I have been using AMS oil for years, it's the best. I started using in my Race Car first then in my truck and my whole family is using it now in there cars, I also like the articles in the booklet very informative Thank you guys

Lots more power and better fuel economy.

First time use on both the GTi and the CX-9, with upper cylinder it certainly helped workout some sluggishness and the cars need it in this cold short trip weather!

It work in my Toyota tundra 2008 I saw efficiency in mileage I recomend this product

I have been using this additive for several years and am a fan. Just like with my MC, I noticed our HEMIs ran a little rough at times, since we moved to SC. Professional techs explained the issues we were having was most likely due to the poor fuel quality in this area. I use one bottle at every oil change. And one between 3 and 4K miles. I haven’t had the hesitation issue, since I started using this additive.

Increased mileage by a couple mpg.

Started using this product every 5K. I don’t know if it’s my head, but my wife is getting better gas mileage as a result.. the idle also has smoothed out when you come to a stop sign or red light.

Since I have been using Amsoil PI my vehicles have never had a fuel related problem. I only have 2 vehicles now, but I buy a case at a time and give it to other people!

I had a friend who's truck didn't like to start in cold weather, he even tried new plugs and wires to no avail. After using just one treatment he said the problem finally went away great product . Thanks guys

Truck has better mpg..more responsive too

This is the first time I am using this additive, yet it seems to be working okay. My 2005 F-150 has 93K on it and I have babied it since it was new. I would use this product again.

I don't actually think my vehicle needs this cleaner as it's low miles with the best premium fuel I can find. It did help milage during and after use though. I look at it as a maintenance item and I'd rather make it to 100k with factory injectors than replace.

I used the Amsoil gasoline additive in my Escalade and Dodge pickup. It brought the Escalade to life and gave my pickup a newfound boost of power. I use one bottle with each tank of gas. My miles per gallon has increased and gave me a quick needed boost. I would definitely recommend this product. I will be using it also in my Harley next spring.

I tried in two different cars. The Subaru went down two miles per gallon. The equinox made no difference. I check mileage in all my cars every fill up and maintenance is written in the log book.

I used to use Sea Foam and then decided to try the Amsoil additive. My GMC Sierra 1500 truck (over 175,000) idled better and ran smoother. Then when the check engine light came on a couple of times, I added this and the light went off! I've used this in my boat (Mercury 75 4-Stroke), as well and it works wonders there, as well. I now have a box of these I use regularly.

This product was everything i expected it to be.... would highly recommend !!!

New customer and just started using Upper Cylinder Lube. In new truck, sounded better on first tank. Will know about gas milage in a few days when we take a highway trip. Gave one to my brother-in-law and he said his computer was saying 5 mpg increase on 2.7 L Ford truck with over 200,000 miles. Gas milage said 30 mpg.

This product is outstanding. I put in a small container every 3,000 with a fill up to keep all the moving parts in the engine clean and doing their job. I find the gas mileage improves. It is vital to deal with cheap gas as well. I try to select the station with the superior gas but it is becoming more of a challenge. The additive compensates for the inferior gas and is a must to keep the engine clean.

Awesome product really helps your gas and fuel system stay clean and running smoothly highly recommend try it and see the difference in your vehicle
