I’ve been using Amsoil products in my vehicles for years, 1st time trying Extended Life. Took a recent round trip to Texas around 2k miles, checked the oil, the vehicle didn’t consume and looked clean (transparent).

Oils still holding level and almost as clean as original at change. Even getting better fuel mileage. Says a lot for a heavy expidition with a 5.4 L.

Firt time I used 20k formula. I changed the regular at 8k plus.. the vehicle told me when. I am excited to see how the car reacts to the 20 k. The oil was nearly as clean as when I put it in.

Used in a buddies 90’s GTR. He said they lose some oil pressure once they get warmed up so he wanted to try the 40WT. So far he says it’s better and quieted the engine down

I’ve been using it for some time and have had nothing but great results in our cars. Best on the market. Trust nothing else !

using it in my 1956 3100 chevy with chevy 350

Been using Amsoil products in both my truck and small SUV now for just over a year, so I’m still new to the game to give solid information. What I have seen over the year is a quieter engine in my 130k + SUV and a slight savings in fuel in my truck with proper maintenance and oil change intervals. It’s a little pricey over other brands but the quality and noticeable difference justifies the price IMO, plus if you opt for a membership you save on each purchase. Amazing product…. 5 stars!

Have been using this synthetic oil since Jan. 2015, on our Odyssey EX L Excellent on wear, performance and maintenance! NGK plugs wore pretty well, no excess oil on any plugs, optimal gas mileage, and smooth running performance with 120,000+ miles!

All AMSoil products are the best in my book, 1964 Galaxie, Used only Dominator 15W50,??? miles and still going, 2003 F150, Extended Life 5W20, 200,000 miles and still going, 2016 Fusion, Signature 5W20,130,000 and going, 2016 Explorer Signature 5W20 over 100,000 and still going, 1991 Snapper Mower 15W50 and still going, YES, I use it in my lawn equipment too, It's the BEST PERIOD!! Nuff said!!

Great oil got over 200.000 miles on my 2011 toyota camry

I started using Aimsoil 40 years ago in my chainsaw. I was so impressed that that is all I use in my truck now.

Changed all of my vehicles over to Amsoil. Great oil. I know my vehicles are protected

Have been using this oil in 2019 Malibu 3.6 VVT and keeps this engine running like new!

Great oil and fast delivery.

Have used this oil in both our car and suv. Excellent results with this oil and filters. Got 9% better mileage in 2.7 turbo suv over semi synthetic oil.

after 10,000 miles this oil still looks new. still slick as when i change it out

I would recommend this oil to everyone that I know.

Best oil for our Camry that has performed so well Best extended drain intervals- Keeps engine clean and running smoothly

Helped with an oil consumption issue on a 03 Silverado 5.3. Definitely the best synthetic on the market. Thanks, Amsoil!

Long lasting good quality oil. A bit pricey but you get what you pay for
