This is the only oil I found that met all the specs for my turbo D.I. KIA AND is guaranteed to prevent the silent knock that takes most of them out way before their time. I never need a drop between changes and I change the oil at 3.5 K miles just because I can.$75 bux for peace of mind. Love this stuff!

Have used your oil for several years.MPG has increased vehicle runs better. Will continue to use.

I’ve been using Amsoil oil on my performance cars since 2018 after i discovered them, I have not been persuaded to go no where else. Loyal all the way!

Was easy to order, receive, and use - great product ! I have used this product since my 2023 Jeep Wrangler had an engine swap performed on it, some may shy away due to the price but I'd share with them that in short you get what you pay for : )

I have used a lot of this oil and never had a problem. just pulled out a engine to swap with another and was surprised to find everything on the inside of the engine was clean with no build up or sludge (i do change my oil every 4000 miles).

In my opinion, Amsoil Signature Series synthetic motor oil is by far the best on the market today. It's been the only motor oil I've used on both the 2018 and 2020 GMC Yukon Denali XL's that I've owned. I place my order on their website and have it shipped to my home. I will continue using Amsoil in my vehicles!

Honestly my sierra I drive maybe 3,000 miles a year compared to My daily drive. So for me it's nice knowing I can change it once a year and have the best protection

I like Amsoil products and have used them for many years so I keep buying them

5W-30 Full Synthetic Signature Series is the only oil I’ll run in my Raptor and Bronco. It’s great oil, and I have no complaints!

I drive OTR, expediting in a Ram 2021 Promaster 3500, high roof, extended van. They have the Pentastar 3.6 engine. Using AMSOIL synthetic gives me the added protection need for this engine, As AMSOIL “goes to heat and friction”and does not run from it, like traditional lubricants.

Excellent product! I see an MPG increase when I use it in my truck.

All is well

I've been running Amsoil for 40 years, lots of good stories to tell, this 5W-30 runs in my sons 1994 Nissan Pathfinder from 100 degree heat in the summer thru the -38 F (started right up!) we had this past January !

I purchased my 2012 F-150 in 2019 with about 150k on it. I’ve been running AMSOIL for the last 5 years and 150k with 7,500 mile change intervals. Engine continues to run smooth and my gas mileage is the same, completely satisfied!

Hands down the best oil out there I have been running ams oil for 18 years

Very satisfied with the oil with the amount of stress due to racing and driving under harsh conditions.

I use AMSOIL and Wix or AMSOIL filters In every motor I have.

Very nice and fast shipping amsoil is the best oil out dear and filters to.....

Best oil I've used great on my car I recommend it to anyone that cares about their car I will use this for the rest of my life thank you for such a great product.

Been using Amsoil for more than 25 years and won't ever change.
