Only use Amsoil, nothing else!!

Noticeably better gas mileage as well as small increase in power

I have been using AmsOil for 20 years and am very satisfied with their products.

Amsoil products have been used in all of my vehicles for over 15 years. Chrysler V8’s. 5.7, 6.2, and the classic 440 Big Block. 0-30 in the 5.7, 0-40 in the 6.2, and 10-40 Signatures in the 440. They all PURR. No Hemi tick or MDS issues that others have reported. I attribute these years of trouble free service to the Amsoil. Best protection available.

Amsoil.. great products

Amsoil.... great products

So many technical oil lab reviews before and after life span, #1 oil produced. Just pull the dip stick and inspect it after 9 or 10 months to prove to yourself. It works.

Amsoil Synthetic Motor Oil improves my gas mileage and smooths my engine sounds. After 20,000 I will be able say more about this Great Oil.

I have been using Amsoil Products in all of my motorized products for about 20 years, these are high end top quality lubricants, I 100% recommend the signature series oils, My Harley loves Amsoil my Dodge truck loves Amsoil and my boat with twin 4.3 Mercruiser's absolutely purrs with appreciation

I switch to Amsoil because the manager at one of the automotive retail shop is the one who told use the Amsoil and they don't even cary an Amsoil so he told there is one dealer that he knows and he gave the phone #. So since then I been using the Amsoil and so far I'm very satisfied with it. I use Amsoil on all my Toys, Mercedes Benz, Harley Davidson, Tacoma and my Honda. I still need the big banner of Amsoil for my Garage. Thanks.

I have been using this Amsoil product along with several others for several years. Their products have been everything they advertised them to be. I have over 166,000 miles on my GMC and recently changed the valve cover gaskets. I was shocked at how clean the inside of the heads were. I can onlt attribute this to consistent oil changes and the use of Amsoil products. I strongly recommend using them. Although they are more expensive than some the benefits out weigh the cost in my opinion!

I have a 2006 Charger SRT8 with the 6.1L. Like most hemi motors, it has the "tick". When I bought it, I used Mobil 1 for the first 2 oil changes, hoping a "premium oil" would help. Had a friend tell me to look into Amsoil, so I started researching. Found many comparison tests, and each time, the results were the same--Amsoil for the win. So, I started using Amsoil. I have now done 3 oil changes at 5K miles, each with an engine flush, and my "tick" keeps getting more quiet with each one. It ain't cheap, but my Baby is worth it.

I have used Amsoil 0W20 full synthetic since it first came out. My last Honda had over 500,000 miles using it. That's why I am using it on my newer vehicle.
