Customer Ratings & Reviews

I bought my GMC pickup in 91 and immediately changed it to Amsoil premium. For years I changed the oil filter at 10,000 miles and the oil at 20,000 miles. Now I use Amsoil XL and change the oil yearly. The truck has 275,000 miles on it and the engine has never been torn down, oil consumption is minor. I also use Amsoil in my wife's cadillac DTS, 3 lawn mowers and log splitter. Their products are the best.

Bought used avalon for granddaughter. Did some engine work and notice some slug. Run amsoil flush and added synthetic back in the car. Always a good move to clean up engine.

Love their product, we use Amsoil in all our vehicles( Kia Soul turbo and 2017ss camaro) Highly recommended

I have been using Amsoil products for 20 years. I still love pulling the oil dipstick out after 5-10K miles of usage and seeing how clean the oil still looks. I run it as prescribed and have two vehicles I have put over 200K+ on each and a third vehicle that has over 300K+. Great product - does what it says its going to do!

My Explorer has 315,000 miles on it and I switched to Amsoil at about the 200,000 mark and I know It’s been a huge factor in increasing its life. The car stopped burning oil after switching and I maybe have to put a quarter of one quart of oil until the next oil change. I stick to a 3,000 interval because I’m anal like that but I wouldn’t use any other oil.

With the cost of the Signature Series motor oil getting progressively more expensive every 4 months, the XL line is a better alternative. I used to use the Signature Series all the time but it has gotten out of hand with pricing.

Since the Signature Series oil has gotten progressive more expensive, the XL line is a more reasonable alternative that won’t break the bank.

Been using Amsoil in everything I own for 15 years. Never had a mechanical failure yet !!

I have found XL to be a great value alternative to Signature Series, if you change your oil every 6 months, or 5-7k miles. I am satisfied with the performance and protection for my maintenance schedules.

Outstanding oil, I am getting better gas mileage and more power while I trailer my side by side. Going up hills and driving on the highways is a breeze now. I have a 2018 Chevy Silverado 1500 with the 6.2 L engine. I have been using Amsoil for over 15 years and I won't use any other oil. I think Amsoil is a great product and saves me money in the long run. Thanks Amoil.

This is the only oil I have used in my pickup, since I bought it new in 2014. What a difference starting on a cold Wisconsin winter morning.

I use this in a F-150 Ford pickup and have since I bought it 7 years ago. I average 12,000 or less miles annually with this truck and it runs like a new engine. When I pull heavy loads it runs smoothly and quietly.

The convenience to be member of the Amsoil VIP, the great quality of the product have helped protect my SUV for at least the last 100k miles from the 300k it has. I will keep getting this product to keep protecting the engine and other components of my truck with Amsoil!

I was using 5W-30 and using the Amsoil site learned the correct weight for my Ford Focus. About to turn a 100k miles I hope it helps me protect this engine as the one on the previous one that has 335k miles and it was my daily and tracked from time to time. Sorry it died on a wrong turn, but the engine and drive train ready to be transplanted on the next body for explicit track use only.

Protects my vehicles. Also the only oil I run in my Harleys.

This is the second time I use this oil since last year; so far it works good it doesn’t get dark as fast as other brands. My motor sounds a lot quiet. I love this oil

Very good synthetic oil if you don’t need the top of the line Signature Series.

The old Truck is running smooth, have to treat well with the liquid gold and give her a tall pour cheers

I`ve been using this product first on my HD and later on my Edge with now 81k. Very little con consumption, drained oil on visual inspection shows no signs of metal. I am also like the fact one can go 10/12k miles before changing, saving time and maybe some $ on the long run.

Awesome oil! Keeping my 2.7 ecoboost f-150 running great
