Customer Ratings & Reviews

Recently rebuilt a 2004 Dodge Dakota with a 3.7L engine. The engine had 148K coming out of a Jeep Liberty with no operational problems. Three thousand dollars later it is in my Dakota and I didn’t get the oil change to the installer soon enough so he put in a Brand-X 10W30. I ran it around town and out to the farm and it performed fine. Then I took a 100 mile trip and got a “oil pressure” light at highway miles near an overpass. Pulled over after killing the key. Oil was full and clean and the engine made no extra noises for the rest of the trip. Oil light would be off on start then come on during operations. So . . . I put in about two cups of Marvel Mystery oil and drive back the 100 miles staring at the light (ouch). Got my box with the filter and 5W30 signature oil and went strait to Pennzoil Lube. The engine was rattling a bit when I pulled up. The Band-X came out with much dark color but still looked clean on the stick. The AMSOIL filter and oil change made the engine purr like a kitten, and it has been ever since. Oil Pressure light went out.

The order was fine except they promised me funnels and gloves. When I used the codem they said it was not valid. So I ordered a kit. Then a few weeks laterm they sent me an email promising funnels and gloves IF I ordered more product. Fool me once, shame on you. Fool me twice, shame on me.

Great product! I especially see the difference when used in my Harley transmission. Shifts smother with no clunking.

This is all I run in my Corvette.

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
