The motor developed a head gasket and head failure at 125,270 miles. When the Ford mechanic removed the cylinder head the top of the head, i.e. cams, followers, springs, retainers, overall head surface were clean with absolutely no debris of any kind evident. Also the cylinder bores still had much of the cross-hatch pattern of the original cylinder honing remaining. The Amsoil Synthetic performs fantastically.

One of few products that I fully trust.

I have been using AMSOIL for many years now. I have 2 old cars 04 and an old Harley. Everything runs quieter and SMOOTHER AND GETS BETTER gas mileage. I will use it til I am gone thanks

Been dying for my warranty to get over to add Amsoil, but I couldn’t wait any longer. My car was begging for this stuff, had to be done. The car wants what the car wants!

good value, quick ship

First time using this. Immediate results as far as less noise and smoother running engine on my 2006 Yamaha Rhino 660.

Great product!. Nothing better for a supercharged Mustang GT. The #1 product out there.

I highly recommend Amsoil it is a superior grade of oil it seems to make it run better and quieter

Simply the BEST! Nothing but AMSOIL in my ZL1!

Used this oil in an Explorer ST. Appears to be high quality. Downside is buying one jug and two quarts to do a six quart oil change. The majority of manufacturers use a roughly 5 quart jug.

I bought a 2001 Suburban LT 4 wheel dive with the tow package in Sept 2000. I immediately had the oil changed to Amsoil the bbest most reliable synthetic oil on the market. I have used Amsoil ever since, The car now has 225,000 miles on it, I have serviced the engine at 100,000 miles The only mechanical problem I have had on this car is the Aternator shaft broke, which had nothing to do with the OIL.

Very very good oil, the best out there. Only problem the shipping, a liter came in leaking. All the cans were covered by oil. The shipper is very rough with the box. Bonjour du Quebec, Canada

great motor oil has quieted down lifters in a small block chevy with over 150000 miles

Shipment was fast and oil was worth the wait. I highly recommend the signature series.

If you want the best oil for your car or truck it's worth the price! Highly recommend!

Great oil that will last at least a year or more. Please market this oil in 4 or 5qt jugs since my car holds 10 qts.

I think this is the best oil you can buy. You also get great service and fast delivery.

Happy with the oil. Disappointed that I never received the free gift of rags but mostly being deceived by the P550794 Donaldson oil filter advertising. The advertising shows as an oversized filter and is actually a standard size filter. I never would have purchased.

I have been a user of AmsOil for sometime. Even though, I have no proof that it is better than any other, except for photos and videos provided by the company. I have not noticed any improvement in gas mileage, idle or oil pressure improvement. It does, however, make me feel better!
