Customer Ratings & Reviews

I’ve been using the signature series for many years and it has never let me down. Feels great knowing I use the best oil available on all my vehicles and equipment.

I just finished my first 0w20 Signature Series oil change after 23k miles. At first I was having a shop replace oil filter (Napa Gold 7002) around 5-6k miles which I had done 3 times. Then when talking with Amsoil Technical Support, was advised it was fine to go 12k miles with the Napa Gold 7002 filter. Just under 12k and before a long road trip, I went to my original mechanic to change oil and filter. This shop is listed on Amsoil website. This time, the oil was really black and dirty. Shop advised me to not ever go over 5-6k miles on an oil filter no matter what Amsoil says. Furthermore, they advised me to just use Mobil1 since it's much cheaper. OMG. I'm not sure if using Napa Gold 7002 filter for almost 12k miles like Amsoil Technical support recommends was safe for my engine? I guess time will tell. I believe in Amsoil products, but perhaps 25k miles driven (90% highway driving) is a bit much? Also going 12k miles with a regular high quality filter might not be good. My long time go-to mechanic I run everything by died suddenly last year, so I no longer have that trusted resource to go to. Think I'm going back to replacing filter at 5-6k miles along with an extra quart of oil and not exceeding 20k miles.

Love all y'all's products Amsoil customer for life!!

Très satisfait

I’ve been using Amsoil products for over 25 years and they have always exceeded my expectations!!!

So far I am very happy with Amsoil products. I use them is all my vehicles. So far so good only time will tell the truth as far as wear and tear.

The best oil I have ever used

Awesome product that will exceed your expectations!

Big difference on engine noise from factory recommended oil to Amsoil. The engine is very quiet and the oil looks cleaner between oil changes.

Great product, I should have been using it sooner.

Great product never have issues with product but this shipment had a leaking bottle which inside was kinda messy but it is what it is I’ll give you 4 star could of been 5

your procuct is superior but getting it where I live is a problem. 1. My order is processed in Edmonton and delivered into the Castlegar Loomis for delivery overnight. 2. It then sits at the Castlegar Loomis for a week. You cannot even drive out there to pick it up as the operater of that Loomis is open only from 3:00 P.M. - 4:30 P.M. and even then he may not be there 3. I think there is a dealer in Creston which delivers next day to Trail. 4. I will not order your product if it is sent to the Loomis Depot in Castlegar again. 5. I will order from the US side and import it myself. 4. I will not purchase any product which is delivered by the Loomis Depot in Castlegar

I USE IN ALL MY CARS, KEEP MAKING GREAT PRODUCTS.........

I've been using amsoil 20w50 Vtwin in my Harleys for years so when I picked up my 22 Ram 1500 it was kind of a no brainer, running 5W20. Highly recommend for piece of mind.

I use it in my cars and run them 10,000 miles + before oil changes. Great not having to worry abt oil changes as often.

I run Amsoil signature oil in every vehicle that our family owns. I run 10-30 diesel oil in my '20 F350 Powerstroke, 10-30 in my restored '95 F150-5L , have Amsoil gear oil in the rear axle, and Amsoil ATF in the transmission. I run Amsoil 20-50 in my Harley TriGlide, including the recommended Amsoil in the primary and transmission. This 5-30 is used in my wife's '20 Explorer 2.3 turbo, and my daughter's 2014 Kia Sorrento, and lastly in my 17 year old grandson's 2010 Explorer Sport-Trac. we are using the factory recommended oil weights in each vehicle. I also use Amsoil filters on my Harley. I am sold on all Amsoil products. I also use Amsoil fuel additives, injection cleaner, octane booster, and even stabilizer in the mowers and our power generator. I am convinced that Amsoil is a great company and very impressed with their products.

Swapped to Amsoil 4+ years ago and have always had good luck with it. I like the 25,000 mile oil change, it's one less thing I have to do throughout the year. It definitely saves you 2-3 oil changes a year depending on how many miles you put on your trucks. I'd definitely recommend.

Use this in my partners Toyota Matrix. Notice a difference in mileage and smoothness of the engine.

I have always run Amsoil in every vehicle I have own, the wife's car came due and I only run the best in them. Amsoil for the win

Been using amsoil in my vehicles for over 15 years. Wouldn't use anything else.
