Customer Ratings & Reviews

I own a shuttle company we ran about 300000 miles a year i run all my vans to right at 350000 before i start looking to replace them and i never lost a motor that lubricant with Amsoil.

I've tri3d other synthetic oils and this is the best I can find great price also and super quick shipments

A buddy of mine recommended this oil to me as he uses it in all his vehicles. I have a 4.0 i6 that’s prone to lifter tick and it had a slight tick with every other oil I used. I started using this oil and within 500 miles it is gone. It starts smoothly even on cold mornings as well. I also noticed that one oil change with this equals 5 with every other oil so saving me a ton on my maintenance costs. If you’re at all apprehensive about the oil or the price I say “pull the trigger” and get it! You save so much more money in the long run.

Just purchased a newer vehicle and trust putting only Amsoil in it. The peace of mind knowing the company, being a preferred customer, and a performance enthusiast makes me confident and content running only Amsoil products in my everyday and performance vehicles.

The only real downside is the price, switching from Castrol Edge to think, I could immediately feel the engine running much smoother, though I would NEVER in a million years go 25K miles on ANY on any oil, though some people would say it's fine if you change the filter, I just wouldn't do it

Amsoil is my go to oil!

My wife’s car is known to have a lot of engine chatter and cam wear over time. I’ve been getting semi synthetic oil changes at the dealer and switched just to get a little more longevity out of the motor Little did I know this stuff makes the hydraulic timing tensioner‘s sounds so much better. Wish I done this a couple years ago.

Fast shipping, excellent quality oil. I have 4 vehicles, all running on Amsoil.

I use amsoil in every machine I own. The results and testing they do proves It is a top tier oil. I refuse to put any other oil in my cars, bikes, riding mower, snow blower, atvs.

First time buyer but I can see why there not cheap$$ This stuff is the best I’ve used in my 20+ years of changing my oil in my muscle cars. I can tell it does the job as 30-40 degree morning and on hot summer days aswell. All and all I would rec for anyone who wants the PREMIUM oil for there baby

I'm not a mechanic, not an oil expert, but I do know my Jeep very well and since i've started using this oil in her I have noticed very obvious changes in the engine performance, gas mileage, and overall sound of the engine. I even started putting the same oil in my wife's Hyundai Accent (both vehicles have over 150k miles) and they are running like a couple of brand new auto-babies. I'll probably never use anything else in any vehicle (and wont let a Quick Lube place ever touch my dipstick again) but I have a feeling this oil is going make my Jeep run until the wheels fall off, and then the engine will go on forever on its own--a sentient being adrift, in search of truth and meaning in the universe. Great stuff!

At my last oil change, I used Amsoil 5W-50 instead of the Castrol 10W-60 recommended by the manufacturer of my BMW E93 M3 with the S65 engine. The Castrol made the engine RPM fluctuate at startup and the engine seemed sluggish until it was warmed up. With Amsoil, the engine RPM does not fluctuate at startup and the engine seems to run more freely. When the engine is hot, there is no difference in feel or performance between the oils.

Great Stuff.

Oil has performed very well and has not burned off in highly modified 700hp M5. I have run Redline and Moly in this car and the analysis of the oil after the first change has been superior to both.

Fast shipping

Oil looked almost the same color after 10k miles as when I put it in. Got slightly better milage with it, engine runs better with it. I just love it and will always use it.

All of the Amsoil oil products are outstanding(incl Trans and differential fluids). Outstanding wear and cooling characteristics. WISH they could solve their availability issues on oil filters.

Very satisfied with products

Ive been usuing the signiture series in my 2019 Ford Ranger from day one and couldn't be happier!! I run Amsoil in all my vehicles and in my motorcycles as well!! Good quality product!! Always inpressed!

After a bit of research I also started using the amsoil oilfilters gonna see if they have them for oil and fuel filters for my cummins aswell
