Customer Ratings & Reviews

great oil, use it in a 5.7 hemi with Lucas fuel treatment (good combo for a quiet motor) Ordered as a "kit" (oil & filter) Brands of filter offerings changed on last order (Donaldson chosen) Really good filter company (even publishes operating pressure specs). Useless if it comes a month after the oil arrives!

I use Amsoil 5W-20 in my 2006 Ford F 150. I am the original owner and I have 135,000 miles on the truck with no problems. I trust Amsoil products.

This oil makes my Passport run smoother.

Great oil, stays clean doesn’t burn off.

Have used this for years. All 225K miles in current vehicle. Had to drop the pan at 200K. No sludge. Very clean.

One of the best oils to use for the Infiniti Vr30 especially in hot climates

Cat go wrong!

Reduced engine sound better fuel economy and more power and yes it was noticeable and my truck only has 40000km on it right around that anyways

Used this oil for years and will continue to do so

Spendy but we’ll worth it

I’ve been using Ams oil in my 5th gen ram since the first 1,000 mile break in oil change. I’m about 30,000 miles in and have not stepped away from Ams oil because I’ve had no problem with it! I buy it online and it ships to my front door or shop in just 2 days.

Great product. Protection well above normal standards.

Great oil. But I've recieved an email a day for over a week asking for a review. So the oil is Great. The spam is annoying. 1 star for constantly spamming me.

I love this oil. It lasts a good 7,000 miles and works well in the Florida heat.

Will NOE run AMZOIL for My 2008 Ridgeline w 140,000 miles.

My order was damaged during shipping but they quickly got it fixed

Received my oil just fine, but its been over 2 weeks waiting on my filters as I go over my oil change more and more. I probably won't be renewing my subscription after October.

I used this for first oil change. First time using Amsoil. The hemi tick in the 6.4 hemi is 80% quieter. I am really impressed. It will be my go to oil in the future!!

I will not use any other oil unless it’s amsoil. Cleans the inside of the engine and stays clean for many miles.

I chose Amsoil and filter at the recommendation of a coworker who was also a dealer. What sold me was his and several others testimony about quality based on oil samples. I liked being able to run the oil for a year, changing the filter at six months based on my annual mileage. Great value for me with my 70-mile round trip commute. Started my regimen when I bought this hooptie with 102K miles on it. It has 225K 8 years later with no issues.
