Customer Ratings & Reviews

I have been using this 5w-30 for years in all my vehicles. It seems to pretty much cover every popular make and model. It's been around for years, before the ultra thin high efficiency fluids, that I just don't trust yet. This is the baseline fluid and as always yielded better than factory fuel economy and a noticable reduction in operating temperatures. Not forgetting mention every time that I have used this fluid I've been able to get high mileage with zero failures. This is pretty much a safe universal oil for most vehicles(yes, even though they are pretty much recommending oil with the viscosity of water now). This will keep a healthy and well built motor into the 200k arena with ease.

Skip OEM Jeep oil and go straight for this. It makes the engine perform and run much smoother than any other oil

I've been using SS oil in my cars and lawn equipment, anything that uses oil has Amsoil in it. Started over 20 years ago when some of my fellow workers in the construction industry were telling me their experiences with it. I switched a small truck I was driving to work to Amsoil SS oil at 108,000 miles used the sampling system until about 185,000 miles. At that time engine was cleaner than the beginning sample at 108,000 miles. At 265,000 miles had a valve sucked when son tore down engine to put heads on it the block was like brand new no carbon or sludge. The timing chain was like new also. Got it back together and drove it until it had 375,000 miles. Not because of engine but because other things wearing out. My son, my son in law, and myself use nothing but Amsoil. Also have some friends that use it.

Awesome product I use nothing else

Same as last review

Bought it for my ecoboost mustang 🐎 Runs smooth and nice 👍

Switched to signature series with my last oil change about 1,200 miles ago. Love this stuff, slight bump in mileage, truci running better than ever.

Have been using Amsoil for about 16 years now and am impressed with the performance and cold weather viscosity of this product. I highly recommend using Amsoil.

Nothing better for my vehicle

I have a 2022 Elantra N and this is the only stuff I put in it. After a couple of headaches when I bought the car brand new at the hyundai dealership their service team is incompetent. Twice they almost put the wrong weight into my car arguing with me that I was wrong when I told them look at the oil cap uhhhh Ya. So I swore I would do all my maintenance and work to my car myself. Besides bodywork. Car drives smooth and I can tell it likes Amsoil by the way the car feels.

:)

This is great oil and has helped me reach the proper oil pressure needed for my LS3 418 CID with a little larger clearance.

I use this oil in my Shelby and highly recommend it for great protection

Been years using it. Was recommended by an uncle who keeps changing cars every two years. Been the best advice.

Oil is great. The free hat with $100 purchase is not great. The hat is super small and made for a child's head.

Made my engine run good. Soon after oil change, I drove 1500 to FL then back to TX. Engine ran smooth.

The car runs so much smoother now.

Best oil

As with the the rest of the product line - it just works. motor runs smoother in the summer time heat and reduced warm up periods in the winter.

will review after some use but I can say for the 60w its doing a great job in my 448 ci in Hemi here in FL
