Best automotive oil money can buy. Only oil I use.

I have a 2003 Ford 4.2L V-6 work van that I ran out of coolant after blowing a lower hose on the highway and not knowing about it until it began knocking and seizing up. I called a ride and went and got some coolant and a hose, changed it out and drove almost a hundred miles to my home. That was at 160k miles. I had Amsoil Signature series 5W30 in it then, and I credit the fact that it is still running flawlessly today with 225k miles on it to that fact. Now, in its advanced age, I use High Mileage 5W30, and still drive that van all over the state for work. You need to use Amsoil. Seriously, use it......

I was skeptical of this despite using Signature Series and still having oil burning issues that improved initially and then got worse. After using this product and checking the oil weekly, it’s dramatically slowed down the oil burning. I will continue to to monitor and keep an eye out on the oil levels to make sure there’s oil inside the engine. So far, impressive. Time will tell.

2011 Ram 1500 5.7 Hemi. The only oil it’s had in it since it’s first oil change! I also use it in my Harley! Can’t beat AMSOIL.

Exelent product.. Keep my engine clean and have the best viscosidad. 100% recomended

Excellent oil

Been using Amsoil since the 90's and have 468,450 miles on my truck and still runs like it's new.

Please read the review I left on the oil filter. Great product!

The best oil on the market. Used nothing but Amsoil since 1977 in all my vehicles I have owned. Yes it is expensive but you get what you pay for these days. Since Amsoil was the first ture 100% synthetic motor oil I have used in many trucks to pull a boat with no engine problems in any of them. When I sold a truck the engine still ran like new. There are now many synthetic oils on the market... but will always use AMSOIL...!!!

I've always been happy with Amsoil as a product, However I think your rewards program needs updating, as i mentioned in a previous email I was quite unhappy to learn that my rewards were going to expire if I didn't use them soon, basically forcing me to make a purchase, even though I was not in at that time of any Amsoil products, well I didn't make a purchase and I lost my points which to me is not a good way to treat your loyal customers.
