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

Tried a few different synthetic oils in my ford 6.2 and always had kind of a slight tick, just changed over to this and it’s as quiet as a church mouse!!! Won’t run anything else now!

If you are familiar with most motor oil, this will be the last you ever buy.

Absolutely the best on the market. I use Amsoil in vehicles, lawn mowers, and even my standby generator. Has never let me down...........

I been using this for a very long time it keeps the engine clean.

I have a car that I used to use fir Uber/lyft, Now I don’t drive that car much, so i use this oil, one oil chance per year, I’m driving less than 20,000 miles a year for sure, save money stay protected
