Running on my Subaru

This motor oil give me confidence in its protection but that’s only from what I’ve read about it. It’s outrageously expensive and it never goes on sale or offers rebates. Their prices only increase, so if you can afford it, it’s a good oil. I’m not sure if it’s twice as good as other premium synthetic oils that go on sale at half the price. Paying 100% more for something that’s 25% better is a choice you’ll have to make.

Great stuff, always feel better knowing that I’m putting the best oil on the market in my engine.

After ordering and getting the membership discount it arrived right on time. Will try to change the oil in my truck soon!

I have a2015 Ram 2500 with6.4 hemi which uses the 0w-40 and a 2020 Ram 1500 with the 5.7 hemi which uses the 5w-20. I have used AMSOIL oils since the first oil changes on both trucks with zero issues. Btw, the 2015 has over 105,000 miles and still runs strong because I maintain it on schedule. I am sold on AMSOIL products.

I use the oil in my chevy pickup change oil every 6 mths never uses a drop starts esy even at minus 20 in maine on snowmobile trips hav been use amsoil pruducts for 20 yrs now never a issue

Amsoil Signature Series has proven to me that long term equipment protection is possible for all my vehicles.

Great oil and wouldn't use anything else in my daughters car

Products are great wish they would send more free stickers, displays, amsoil advertising, for being a loyal customer

works great in a 6.2L v-8

Best decision choices I have made, always used amsoil in my bikes, but decided to do all our vehicles, top notch definitely recommend, runs so much smoother and better protection

Hands down the very best oil on the market today

Best oil in the business

Been using AMSOIL for long while. Just got different vehicle , oil in car was choppy and noisy. Added this oil, AWESOME. Smoother and quieter. Best durability for the engine!!

This is my only go to oil! It's proven to me time and time again why it's the best and I can't see my using anything other than this in my vehicles.

Been using Amsoil for a long time. Wouldn’t put anything else in my vehicle. Definitely worth the money

I purchased this product because my hubby, who is now in heaven, used it. He believed in using synthetic oil for our vehicles because synthetic oil is better for the engine. I haven't used the new shipment yet, but I will when it is time to change the oil.

We own a 2008 Corolla ,which requires 5w-30. We were running a leading Synthetic oil which rattled on start up ,until the lifters pumped up. As soon as we changed to AMSOIL all the cold start rattle stopped. I have a history of AMSOIL in all my cars and this has always been my oil of choice!

I have used this oil anytime I could

Great Product: I have used this Product and have noticed that my car seems to run smoother than before.
