I let the quick oil change stations change my oil with my oil instead of theirs.

I changed to amsoil from gm dexos as I wanted something better for my Cruze. After 10k of running dexos as it was included with the car, I switched to amsoil and immediately noticed the engine running quieter than with dexos. I am happy with the change so far and am looking forward to see how it holds up as I only have 1500 miles on it so far. We'll see what happens when I get into my second oil change.

I have been using Amsoil in three of my vehicles now. One I sold with about 280k miles and it did not use any oil. As soon as I got my new car home I change out the factory oil to Amsoil. I have a Jeep Wangler that I put a performance Chevy 350 in., 340 hp 390 ft lb torque. I have had over heating problems with it and have driven it all day with temps over 230. The oil did not cook and I still don't use oil, I've put over 60k on this engine using the Z Rod oil.

I use this product 0w20 because any vehicle I drive is an investment, and I keep my vehicles in very good condition.

I use this oil in my vehicle because it meets my manufacturer''s specifications. Also, I noticed after about a hundred or so miles that a nuicanse tick went away.

The 0-30 works well in my old Dodge and I plan on using it from now on.

2010 Ford Explorer and soon to be 2015 Chevrolet Silverado. I do have other gas powered items, lawn tractor, edger, tiller, etc. I really need to convert them over as I have had nothing but great results with your product.

Have used AMSOIL oils and filters for several years now. Can tell a difference just by loooking at the oile when changing. Other oils when drained show wear by the dark color. With AMSOIL it looks like it could go a few more thousand miles.

I travel a lot every week. I usually drive over a thousand miles each week so I don't need to be getting ripped off in quick change places. I don't really keep track of how many miles I go in between changes any more and I've had no engine issue that relate to wear. This product performs as advertised.

this oil has been synthetic for a long time .I was just waiting for 5w-50 to come out.

I bought this car used - it's a 2008 Mazda3 S - from my best friend, so I knew its full history already. He's run Amsoil in it since brand new, and I plan to continue the same. It just rolled over 200,000 miles last week, and mechanically, the car has been in the shop twice in its lifetime - both for air conditioner issues. It doesn't burn or leak oil, and never has. When something is treating you this well, why would you switch to anything else?

I use amsoil in my hellcat it quite at my lifters and seems to add more smooth power

There are a lot of good synthetic engine oils on the market, but none better than Amsoil. I've been using it in all of my vehicles for seven years now, and haven't had any type of engine issues related to wear. No, it's not the least expensive synthetic oil, but I don't "cheap out" when it comes to taking care of my cars. Only the best oil and filters for my machines. It's cheap insurance for my Hellcat. There's really nothing more that needs to be said.

i've been using this oil for many years and i am completely satisfied with it.i actually gained about 2-3 miles more per gallon of gas.i usually change this oil and filter every 8-10,000 miles and when i do it is never black.

love this product

The Best Engine Protection on the Market ! I drive a 2012 Toyota Camry & The Manufacturer recommends 0-20 Weight Oil..... which is supposed to provide engine protection up to 100 Degrees. Well I live in Las Vegas Nevada where Summer Temps can reach 117 Degrees..... The signature Amsoil 0-30 is far more protection

I have been using this oil in my dirt bikes for 40 years now!! I mix it with avation fuel at 83 to 1. they have always ran great!!

This is the only product I trust in my 738hp 2013 Boss 302 Mustang. This is my daily driver and play toy. The signature series has great life in my supercharged application which makes the comparable pricing a bargain!

My '13 Boss 302 takes an odd oil grade....5W-50...and only a few brands offer it...and when they do it's usually formulated for older Muscle cars....so it's loaded with Zinc additives...very detrimental to modern catalytic converters....plugs them up. AMZOIL created their Signature 5W-50 specifically to address Fords running the HO versions of the newer 5.0 V-8s ! The Boss loves it for Breakfast and never Burps. Thanks AMZOIL!! Super Product!

Used in a 2015 Ram 2500, 6.4 Hemi. No tics, Slightly better fuel economy.
