good oil use on boat too. got rid of mobile high mileage oil o 20

Greatest of all time, not much else to say about it.

I changed the oil on my 2022 Hyundai Elantra N before driving it back to Florida from New York. I drove the car up to NY and averaged 33.5 MPG. After making the first oil change with Amsoil Signature Synthetic I drove back and averaged 35.5 MPG. The only thing I can attribute this improvement to is the oil. That's the only change made to the car. I have used Amsoil Z Rod in my vintage Alfa Romeo and in Amszoil transmission oil in it's manual transmission and differential all with great results such as less gear wine and smoother shifts, so I now see the added MPG in my new car with your signature series oil. I'm a believer in your products!

Been using Amsoil in my vehicles since 2002 always seems to do me right.

I have been using this synthetic oil for over 25 years. I have used it in my 2011 Acura RDX since I've had this car, and now have over 100,000 miles and have never had to add any oil between changes. I will use nothing but Amsoil!!

Nothing but the best from Amsoil, from the shipping speed , customer service, and the best quality product you can ask for .

Great company with outstanding products. Ordering and shipping speed are really good

Been a customer for 10 yrs, keep raising prices, I’ll switch to other oils.

Put this in my 2020 Silverado and mileage went up by 2/mpg and truck runs cooler pulling my trailer

Amsoil is very good oil. My cavalier has 295k on the odometer, and I would like for it to last a lot longer.

Please make your 0W40 Signature Synthetic oil available in 5 Quart jugs and not just in 1 Quart bottles.

I've used Amsoil for many years, and it has always performed to the highest standards. I would, and I have recommended its use for any car, truck bike...anything that needs oil, this is the one...Edd

I use this oil in my Dodge Challenger 5.7 HEMI and have had amazing results. This oil makes my car run like a new engine after every oil change. I love it!

Amsoil is simple the best oil to keep your engine running for a long, long time!!!

Just great oil

I have been using Amsoil for may years in various vehicles and now prefer to use it in all of my vehicles.

I use your product in every thing I have that has an engine that requires oil.

I always use the best!

Ran all the other big brands trying to see which quieted the turbo the best, Amsoil within 500 miles has the car running as smooth as it ever has . 2016 vw jetta
