Customer Ratings & Reviews

This product runs oil temps in line with my previous brand(Schaffer’s) but dramatically decreased the number of regens needed. I will keep usong

Great oil, My truck has almost completely stopped using oil, engine runs quieter and smoother. I've tried most brands

Great products,fast delivery. Peace of mind

For the last 50k miles or so this truck has had amsoil and there is a noticeable difference in how the engine sounds at idle. May not make sense but its true. Im not nice to this truck at all and I have comfort knowing that my oil is there for me. When my rods leave the block it won't be from a lack of lubrication

second oil change with Amsoil great product

LD Synthetics was easy to communicate with and had great advice. Highly recommend

Amsoil always arrives in a timely fashion and my engine loves it. Would recommend this oil to anybody who wants the best for their diesel.

I run AMSOIL in my new Cummins and it’s amazing. I had my oil tested by an independent lab and it is better than any other oil on the planet!

Up to 25000 miles for next oil change. With amsoil oil filter and product. Recommend oil sample's during long drain interval.

Excellent product, first time running AMS oil I noticed my diesel run smoother immediately.

great oil love it

Keeps my trailblazer Ss running strong

I will not use anything else, Works great, Highly Recommend

I love this product has not let me down

Always makes my Truck run like new every time I change the oil. That’s not an overstatement either, I’ve used royal purple for years and then I decided to switch over due to all my buddies who I know run Amsoil. Best that money can buy

Shipping was quick. Great buy. Comparable to what’s at your local stores. I have both engine oil and differential oil in my truck. Love them both.

Great oil

This is great oil, I use Amsoil products in all my vehicles and love it! Wouldn't use anything else.

Will use again

I've been using Amsoil for quite some time now and after switching over to Amsoil Synthetics I noticed a big improvement in the equipment engines with there synthetic oils . In the cold weather that we have in the N E. the engines start better, and stay much cooler in Temp's in hotter weather over the other brand oils ... The synthetic oil from Amsoil is much more slipperier than the other oils allowing the engines have lower temps in hotter outside temps'. staying cooler and running better and longer life from your engines , the oils make the engines run better with less friction on metal internal parts . Giving a little more power and milage from you machines weather a Truck pickup,ATV,Tractor,big or small and your Zero turn mowers , chainsaws, weed wackers . Yes Use it .
