Makes the idle smooth and lubricates good

As advertised great product.

Great service

Impressed with the quality

I run this in my Gravely mower, Honda 420 and Polairs 1000 after every oil change along with 90 octane non ethanol. Never have had any problems

Use in every tank full in 2004 F250 v10 , seems to be cost effective , most of my use is short trips 8 miles average each day so don't expect better than 10 mpg from the V10

I use it on every 3 car fills.

I have been using this product in my Jeep for over two years. I can’t see inside my motor to see if there are any changes but when I add to a tank of gas I notice the engine runs a bit smoother and quieter. That is evidence to me it is doing something for my engine. It is relatively inexpensive insurance.

Great use it in all my vehicles. Good stuff use it it my four-wheelers & lawn mower as well

I’m not sure how a consumer like me can accurately review a product with proof without proper testing labs, controls etc., that would require long-term observation and internal inspection of engine components affected. So, I’ll just share the knows. I’ve used this product in my 08 Sierra since it has had 7 miles new and no issues, complaints or problems and I continue to use it every oil change. That’s about all I can say concretely. There’s definitely no harm using it.

Very satisfying with the product and results I get from it.

Like very well

Keeping your engine and its valves free of carbon build up is big part of the engine lasting longer and most importantly running properly. Do yourself a favor and get yourself this product to prevent build up and ensuring your car runs optimally.

Combine with the PI great results

YOUR SHIPPING COST ARE OUTRAGEOUS. PRODUCTS NOT OFFERED IN STORES LIMITED AREAS. I WON'T BE BUYING AGAIN. THANK YOU.

Seeing that every other product has impressed me I am going to assume this is doing its job.

When you can't really "feel" a product making a difference, but the science and concept seem solid, you just have to let it prove out. Well, I have a 2018 Grand Cherokee with 97K on the 5.7 hemi and it has just as much power today as new. No smoke on start. Used UCL since 14K miles (in addition to Signature Series oil) in every tank without exception. I'd have to say it works!

"The difference between Amsoil fuel additive and others ? Amsoil works ! " Great stuff !
