Easy to use

I have been a long time user of AMSOIL products in everything I own and I have found that the 5W20 is the absolute best engine oil. It has almost the same low temperature benefits as the 0W20 but less burn off than either the 0W20, 0W30 or 5W30 engine oils. It is the only oil I use for my customers now.

When I bought my '13 Subaru Empreza, the dealer said that the engine must use synthetic 0w-20 oil, so I of course chose Amsoil's 0w-20 Signature oil. FYI this car is suppose to have a high oil consumption engine, but I have never added any oil. Another thing the dealership told me is NEVER EVER USE MOBIL 1 oil as it will wreck the automatic cam timing mechanism.

I use this in two vehicles a 2001 blazer and 2003 silverado hd

I got in an accident a while ago. I got out of my truck to exchange driver information with the the other driver and noticed all the antifreeze leaking out of my truck do to the accident. When I seen this I went back to shut off the truck that was still running so the engine wouldn't overheat but the door was damaged and wouldn't open! My truck stayed running for over an hour with no antifreeze in it yet the temperature gauge didn't move, amazingly it never even came close to overheating. I owe it all to Amsoil''s superior oil that saved my engine! My truck is still running like new with over 380,000km! I'm a firm believer in the Amsoil line up and use it in everything that I own!

Excellent product, helpful staff.

Uses all the time

Great oil. No problems

I do all my cars motorcycles lawnmowers etc. once a year

I found this product and all the others produced by Amsoil are top quality, and found they protect my vehicle's and equipment that I run Amsoil in

Great product. Been using Amsoil for about ten years. My only complaint was the shipping charge. Amsoil has been running specials for preferred customers were they've been offering free shipping on orders over over a certain amount. When they offer this deal that's when I place my order.

I am a retired senior citizen with put a lot om money. therefore I am thinking of ONLY getting the next grade down on my amzoil purchases, instead of the signature series. The product is so good ,I will save money by going to the next step down in quality, which is as good as any other top of the line motor oil. How many products do yoou buy where you can get their second best and be better then any of the competition..

I use Amsoil exclusively in all my vehicles and I have do so for years. The cars include a Jaguar Vanden Plas with 136,000 miles, a Hyundai XG350 with more than 360,000 miles, and a 1990 Chevrolet Celebrity 3.1 V6 with well over half a million miles on it. None of them have ever required any significant engine work and all drive well, use almost no oil and get excellent gasoline mileage. Additionally, I use Amsoil in a restored 1932 Ford V8, again, with no problems at all. There isn't any other oil I would even consider purchasing. Obviously, I use different Amsoil in different vehicles according to specifications.

My car seem to run better and I get better gas mileage.

I use Amsoil in both my car and my motorcycle! Better than anything out in the market!

I have been using Amsoil for over 20yrs. I use it on my cars,suv's,motorcycles,lawnmowers,boats,&jetski's!! In the long run it is the "BEST THING" you can do for your machinery!!!

my '05 Mustang GT is a daily driver ( winters too ) with 165,000 kilometres ( about 100,000miles ). I only use Amsoil products and whenever I do oil changes at the dealership/shops, they always comment on how clean the oil still is - although you can go 1 year before changing, I change my oil sooner as it is a daily driver in a busy,dusty environment. I use the EA011 oil filter plus steering/transmission fluids and Severe Gear rear differential fluid and Slip Lock additive. I used to use Amsoil brake fluid but it can no longer be sold in Canada. Thanks Amsoil for the great products and service. Kevin Miller

I use Amsoil in all of my cars and they see a good amount of abuse from track days and autocross. Amsoil keeps my cars going strong. Proven to last longer and it does. Worth the money up front because you'll spend less in the long run.

This best lubricant in the world hands down!

I have been an Amsoil customer/member for over a decade. This is probably one of my favorite companies around. Thank you for an excellent product and customer service. Oil & full-flow EaO filters keep my vehicles in tip-top shape year in and year out. I even go as far as testing the motor oil through an independent lab, the results are top-notch wear and tear. Without reservation, Amsoil is hands-down second to NONE!
