Quality product. Expedition had 418000 when I sold it. Sporttrac has 347000 and going well F150 at 190000 purring.

Great Oil! Run it in my modified Camaro SS. Will never use any other oil!

Great oil

Beat oil I’ve ever used. I’ve put over 200,000 miles on my truck and it’s still running strong with no problems. Would recommend this product to everyone. Plus you don’t have to change oil as much.

Is good for high mileage engines

I have been using the XL synthetic in our Ford F-150 & Explorer since it was introduced and believe it provides great protection as well as no oil leaks after switching from Ford's synthetic blend.

My nine cars all have Amsoil without any failure. It’s difficult to evaluate a motor. Blind product as long as no failure. What I really like is the long change interval, since most my cars sit, and get little mileage.

After seeing a video on a youtube channel Project Farm, he ran a series of tests and Amsoil came out the winner. I was impressed, so I changed my oil for the first time with Amsoil and will be from here on out. I am trying out other products now, and have not been disappointed.

All the AMSOIL products we order are processed quickly and with absolute accuracy. We use AMSOIL in all our vehicles (boats, ATVs, trucks & SUVs)

Great product. I use Amsoil in all my vehicles.

I use Amsoil products in all my vehicles and ATV’s. Have been using this product for at least nine years. Great product!

After almost five years of Pennzoil and an engine slowly getting to be noisy first I ran the signature 0w40 and noticed a great improvement but decided to give the XL 10w40 a try for the summer camping season and so far this oil is working beautifully no MDS codes and finally an engine that’s as quite as the day I bought it. I do plan on running this from now on in my Ram thanks for a great product

Perfect for my 2018 GMC duramax.

I did not believe the ads about this oil. When I first started using it , I would send my used oil off to have it tested and the report always showed that it could have been used longer. This was back in 2005 so I started changing my oil at 25000 miles. I have been doing this in all my vehicles. I believe in Amsoil will continue to use their products. As for the Octane Boost, I am going to try this for the first time and will let you know any results.

i use this in everything i have, used it in the 70's and saying what i said in the review about the 5w-20, alot of memories and alot of confidence in it today

i use all these in everthing i have, i remember in the 70's this came in a qt can and cost alot more but it was worth it, as young airmen in the usaf we tested it ourselves in many crazy ways and was always amazed at the results, i have memorys and confidence in it's protection

My engine loves it

I love all the AMSOIL products I run it in my 6.4L SUPER DUTY my generators and riding mowers. They all run a lot better using these products compared to all other brands.

I have been using all Amsoil products for many years and have never had a problem. We use in F250,Road Race car. Racing Boat, and all the family vehicles. I use all there accessories they make. I would say that all there products are a 5 on the 1 to 5 scale. You can’t go wrong.

For the last 15 years or so I only use Amsoil in all of my vehicles; car, truck, motorcycle, lawn mower & snow thrower. I drive under 7,000 miles a year in my truck and with that few miles the oil only gets changed one time so the XL makes more sense than the signature oil; however I have used both and at oil changes oil still looks pretty clean.
