Customer Ratings & Reviews

By far the best motor oil. Get 10k miles between changes so it a great value.

I noticed a difference in the revving of the engine when I took off after the oil change. Feels like it has more horsepower seat of the pants power.

I’ve been using AMSOIL products for 16 years and I find their service and quality unmatched.

Best oil you can buy. Better fuel economy, overall performance and engine protection. And it’s 100% synthetic.

Good product fast delivery good price

First time ever using AMSOIL. 2012 crew cab 4wd Tindra 170k miles. Kept reading reviews on Tundra forum, so decided to give it a try. Not expecting much, lime oil is oil, but thought it would better for the motor. From day one acceleration was better, motor was quieter, oil guage needle actually moved with acceleration. Noisy start ups gone. I could not recommend the product any more based on my experience.

Came in quickly good quality oil ams oil is all I use in all of my vehicles

I am using AMSOIL for more than 10-12 years 0w20 on my all 3 cars 2010 CRV, 2017 RDX and new one CX5 Mazda never had a problem with any of the engine on the CX5 just change the oil after 1,000 km with amsoil and will be only amsoil for the next 10/15 years. Overall 5 starts out of 5 and delivers never disappoints.

Very pleased with this oil. I run about 5,000 miles between oil changes and it still has good to fair color when I drain my 2016 Silverado used for towing my camper trailer.

I wish I had made this switch sooner. Amsoil makes the GMC seemingly run smoother. This is the first round of using it and I really like it so far.

Online select was pretty easy , the delivery was fast and i like the product .

Great synthetic oil for my 04 suburban 5.3. I ran the fuel additive and new oil the day I bought it and within days it began to run smoother and felt like it became more responsive during acceleration. And at idle, it would run very smoothly! My friend has been running this in his vehicles for years and why am I glad he recommended you guys. New life lawn customer for this amazing product! Thank you!

Best oil

Best oil around I use it in my commercial mowers with my landscaping business running this oil every day in high temperatures outside makes engines run so much better .

Only use this oil on my 1934 ford 3 window coupe. Very happy with the oil.

Best oil. Been using if on my 2010 Kia soul 2.0. And also use it for my 2020 mustang gt. Works great on both my vehicles. Plan to use on my 2025 Honda civic. Best chose i ever did

I normally special order my oil, (0-16 full synthetic), from a local parts dealer but they stopped doing that for customers...so, I researched and ordered directly...so glad that happened, because not only did I come out $10 cheaper even with shipping, I dont have to make the 30 mile driver to get it...and it was here very quickly too! And the emails kept me in the loop with the delivery estimation, etc...just a great experience all the way around.

This is a great product. Keeps the engine clean. One of the best synthetic oils on the market

This oil quieted my grandmother’s 2014 Ford Explorer with 160k miles. Overall I would recommend this product.

This is the first time using this grade of oil. If it performs like the signature series, it will be a keeper.
