AR9100 Friction Modifier - 1 Gallon Bottle For Treating Up To 128 Quarts Of Engine Oil Review

I have been using this for years. It insanely improves Mileage and same with engine wear. Get even better mileage pu adding to t rd and mission auto.or manual and differentials can also be used in power steering.

This is the oil additive to have for the 6.0L Ford diesels. We have two of the 6.0L diesels and literally hated to start them in the mornings. With this additive, no more dreading the starts or trips to Ford for injector repair! Hardest thing to do now is keep my foot off of the accelerator because it is so much fun now.

This stuff is great for the longevity of any engine. Their fuel additive is even better for any diesel engine. Pure snake oil, no benefits whatsoever.

I was told to add this in your oil. I was amazed to see the oil still have some life after 4,500 miles before my next schedule 5k oil changeSeems to workFord motor likes

I noticed that my Harley, Powerstroke, and Mustang EcoBoost are quieter. Probably less friction. I send oil samples to a lab at each oil change, so I monitor my engines.

Hands down best stuff on planet earth! If you don't know anything about this product you have to go read the information on the website first.Use this in my diesel and all gas machines. Noticeable difference, better fuel mileage in me 6.0 Excursion and absolutely no problems with cold or slow starts because of sticky injectors. My car and motorcycle also received better fuel economy along with smooth idling and driving. I would suggest this to anybody with a diesel and also recommend pairing it

I've tried this in all my vehicles. F250, VW Jetta, Motorcycles and have yet to see an improvement or difference. Mileage is tracked with each fuel fill-up

Could not get 6.0 started without the battery dying on a 05 6.0 ford. After using recommended dosage and switching to 5w40 truck started without a hassle. Pure miracle. Now only time will tell.

I'm a firm believer in this product. I have a vehicle that has over 200k miles, I originally purchased it with 140k (chrysler 3.8). It had upper end noise from sticky lifters or something. Added 4 oz+ to my engine oil change of mobil 1 synthetic, and almost immediately it started quieting down. Over the next 100 miles it got smoother and quieter. It had a lot more power/torque from it infiltrating the dirty piston rings too. I've used it on several other vehicles in my roster, family members…

Its worth the price!One gallon treats 128 Quarts at $1.55 a quart treatment.The 16 oz size comes out to $2.55 a quart treatment.You basically save $128.00 by buying a gallon, cost is really $71.00 a gallon if you compare it to buying the 16 oz cheaper size.No brainer to buy a gallon!
