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.

this is the best oil i have put in my cars and truck and all my motorcycles thanks.

Joining AMSOIL was a thing to do

Good upgrade than any synthetic oils. Engine runs cooler and quieter. I put Amsoil in all of my vehicles,lawn mower equipment,generators. I replaced all my fluids in vehicle to amsoil.

I use these filters because of the rated high quality. Trust their products!

I have been using Amsoil for 10 years in my 2006 Volvo XC90 Turbo and at 177,000 miles it still performs like new. I just bought a 2008 Mazda 5 with very low miles, 53,000, and when I changed to oil to Amsoil the engine sounded completely different. Very quiet, with a little more power, and much smoother during acceleration. Years ago I tried another synthetic and it wasn't even in the same class as Amsoil. I will continue to use Amsoil as long as I am driving cars.

Good product and quick delivery, highly recommend !!!

Good stuff

I’m still old school in that I’m changing the oil every 5K or less regardless of a car saying it can go 10 or 15k. This is what I consider to be the best oil option for those changing their oil frequently.

Have had good performance with Amsoil lubricants in the past and I don't expect that to change in the future.

Highly recommend Amsoil!! Great product!!!

Great product, engine runs smooth and cooler.

Easy oil change, one bottle for majority of oil. Engine runs great, runs cooler. Great product!

Oil was still a little clean after used.
