Customer Ratings & Reviews

I have a 2016 Jeep JKU that I’ve owned since 2019. I bought it “off lease” so I had access to all its service records, which is something that is top priority for me. Although the CDRJ dealership had done all the Jeep’s service since new, I immediately switched to AMSOIL when I took delivery. I drive the Jeep between 5 and 6 thousand miles per year, so oil changes are done every mid-December. I added a Baxter adapter, converting the 3.6 to a spin-on style oil filter to eliminate dry starts, that in combination with AMSOIL keeps my Jeep running like a champ!

I've been using this in my car for 5 years and never had any issues. I love this product so much that I put it in my daughter's suv. I also use their differential fluid no issues with that either. I fully recommend this product

I like the idea of getting the best oil money can buy delivered to my front door at a very reasonable price 👌

Nothing but the best goes into my vehicles. Gives me that piece of mind and extra protection if I over extend my oil changes. Been using AMSOIL products over a year and no turning back!

Great oil

Best oil out there. Used for many years now after disappointment with other products.

Best motor oil I have ever used and I have tried them all. If you are reading this review, try it and see for yourself.

I don’t see oil better than!!

Recommended oil changes for a 2019 Jeep Wrangler Rubicon are 7500-10000 miles. I won't trust that to just any synthetic oil. So I chose Amsoil... giving me the peace of mind and confidence to drive anywhere, anytime, in any weather conditions. I trust Amsoil products and use it in all my vehicles.

I use Amsoil in everything that uses oil. This was put in my 25 Rangers first oil change at 1k Put 250k on my F150 and it's still clean inside and original turbos and chain.

Very quality oil

This oil has worked great on my 8.1L dually. 8.1's are notorious for oil consumption. Definitely noticed a reduction in consumption when I switched to the Amsoil Signature 10W-30.

Been using amsoil for years. Hands down the best there is period!

Great oil, I've been using Amsoil for 22 years and I wouldn't put anything else in my cars. Over 500k miles on my Sienna Minivan and still going strong, no leaks no oil burning I'm amazed and so is my mechanic how good this oil is.

Absolutely the best.

good oil

Hands down the best 400k toyota highlander EV

Hands down the best oil.... 400k toyota highlander EV!

I’ve been running 0W-20 Signature Series in my 2024 Civic Si and I’m honestly impressed. This oil handles heat extremely well — even after aggressive mountain drives and hard pulls, it stays consistent and doesn’t feel like it breaks down. One of the biggest things I’ve noticed is how stable it is. The oil level stays exactly where it should be, with no noticeable burn-off or loss between checks. The engine runs smooth, quiet, and responsive, even when pushed. If you drive your Civic Si hard, deal with high RPMs, or do a lot of spirited or mountain driving, this oil definitely holds up. Great protection, great consistency, and real confidence under heat.

Excellent oil! Improves gas milage a little, my vehicles just run better and smoother in addition to longer drain intervals.
