Customer Ratings & Reviews

Used this oil in my new to me used Cherokee. Changed oil about a week after I got the vehicle since the dealership did not change the oil during their prep for sale. The oil seems to make the vehicle run smoother. We’ll see how in holds up over the course of the next 10k miles.

One of the best oil that I use in all my vehicles and bike I can tell a big difference in running this oil in all my vehicles

I use this oil first when I switch to Amsoil Signature or other 100 percent synthetic oil. I run it for about half to 75% of the oil change interval, and also add about 4 oz of Marvel Oil. This cleans out the engine well and preps it for the premium synthetic.

So far so good, mpg already improved, car feels smoother and runs better. I'll stick with this brand for a while, actually thinking of going into business with them.

Great product at an affordable price

I prefer using Amsoil to protect my engine in our high heat climate. I prefer the convenience of a longer drain interval allowing me more leewya in when I'm not able to change every 5k miles.

Been using this oil in my 19 Expetition and 09 Civic for the last two years. Engine runs smoother and has 8-10k mile service internals with no oil consumption issues.

I have been using Amsoil since 2008 in all my vehicles and motorcycle. I trust the product and want to protect my investments with the best.

Good oil Take care my engine

this stuff is great, i use it in my mowers, trust it and its protection

I use Amsoil in all of my vehicles. It is a little more money then the conventional oil you by at you local part store but is well worth every penny plus the warranty is worth it alone

Great product, can’t go wrong !

I use AMSOIL in everything I own and it has never failed me one of the best products I have ever used. Highly Recommended!!!

I've been using AMSOIL for over 15 years now. My brothers have finally started to listen and this was a birthday gift for one of them. I can't wait for his reaction because his car has 100K on it and he's probably been using all sorts of weird stuff. Or even worse may have went to a quick oil change center where that oil is very questionable. I know he's going to feel the difference in how smooth things becomes and it ups efficiency. Keep up the great work AMSOIL, you really are the best!

Great oil for maintenance. I got my first new car and will be feeding it only with AMSOIL. It's simply the best and gives piece of mind that my new ride will last a lot longer than all of the used vehicles I've had. That said my first use was in a Jeep with over 100K. I switched to AMSOIL and it made a dramatic difference in ride quality and efficiency. I ran that up to 225K before I sold it.

Great oil for my fleet vehicles that get 3000 mile oil changes never an oil related failure

shipping is a little high.makes your product a little out of reach.

So far so good, fast delivery to my front door. First time using Amsoil, look forward to using more of your products.

I used this oil in my son car because the oil change system light up every 3000 +- like clock work. the car is a 2009 Dodge Caliber.

Okay, maybe the title was a bit dramatic, but I can explain. Last month, I purchased a 2012 Fiat 500, and it was in atrocious condition. The previous owner did not maintain the vehicle, and it was barely running when I found it. I flushed the engine with an AMSOIL engine flush, and the oil was black as if it had been in there for over a year. Right now, I’m running the AMSOIL OE 5W30, and the engine feels and sounds so much better. It still has a small oil leak, but that’s probably a gasket. I already use AMSOIL in my other vehicles, so I always have a stash on hand. I highly recommend this product.
