Customer Ratings & Reviews

I like to use Amsoil OE Synthetic in vehicles where good protection is needed but budget friendly is key. I have a couple vehicles that aren’t driven daily nor are they pushed hard when used. OE is the perfect solution for these vehicles.

Use this in 4 of my vehicles and have great confidence in it ,definitely great oil

My 2001 Seville,bought used,always had an engine tic noise even after an oil change. It needed 3qt.Started it up and no ticking noise.Just started using Amsoil in my Harley,so far good.

This is the best oil that I have ever used, Don’t buy any other oil until you have used Amsoil.

Love the way how the product arrived and performs/works better than the average

Wow great oil, it's extremely nice to do my first oil change with such high quality product. You can really tell the difference after the oil change. Amsoil is such a great product to run in your vehicle.

Have been using this oil for a few years now & will continue to.

Amsoil is a great product

Bought this as a part of a convenient oil change package from Amsoil. Came with the right amount and seems to be functioning as expected.

Exelente producto buena calidad

Best oil I have used since I started to drive.

So Far So Good, The oil is working great and staying clean

Great product.

this is the lowest quality oil Amsoil has to offer (when compared to XL and signature series). I've driven about 3k since using this oil and the oil is still clean on my high mileage TSX. I purchased more of this and don't plan on sending samples as well to Blackstone. Purchase the car from a buddy who had it 9 years and he took care of it religiously as well. I plan to keep this car for a long time.

Been using amsoil for years. Very good lubricant! I use it on my 15 F-250 diesel and on the wife's ride. I 100% recommend amsoil.

very pleased with product and fast delivery

Works great internal parts are well lubricated cant smell or feel any slippage, product works great even got a complimentary coozie with the order thank you.

I sometimes try amsoil when they run the free shipping deal, not sure I'm really preventing anything by using this vs. wallyworld name brand "synthetics", as i usually change oil prior to 7500 miles regardless

Very pleased with my vehicle after this oil/filter change noticed a difference immediately car picks up smoother, I will use this oil for here on out

Amsoil has been the operating fluid on all my vehicles. My original was for a 7.3 Powerstroke, that through routine sample testing was able to get over 60K miles before doing a full oil change. Sampling was always done with a filter change. In the end, Amsoil always let me know when it was time to change. Engine is now approaching the 300k mark.
