I have been a long time Amsoil user myself for all my racecar/street car applications. When I opened my shop it was only fitting to stick with the best! All my customers cars/builds get Z-rod or Dominator series and with great results.

Use in my 1969 Corvette. Plan to start using in my 79 280ZX and 80 Bronco

I wanted the best flowing highest zinc content for my Hemi Charger. Amsoil was my choice. Cost a little more but only the best for my baby!!!

Great oil for your vehicle. Wouldn't use anything else

Excellent product and protection. After doing much research will only buy this product to protect my classic sports car, and daily driver.

I use this oil in my '93 k2500 suburban with the 454tbi motor, It has a mild cam that calls for a zinc additive. I get my used oil lab tested and the tests show that this oil holds up better and provides more protection than the previous high-zinc oil I was using. I now use Amsoil in all of my vehicles and recommend it to friends every time.

I run AMSOIL oil and gear lube I all my antique autos. Unbeatable protection in my opinion for older, seldom driven vehicles.

Inuse it for my tranny and motor oil

I think this is the best oil for my '68 Firebird.

I choose this for my 79 Mustang as it has a non-roller cam and I want to ensure the longest wear and service from the cam and the engine. I trust this oil to meet the needs of my car which are different than modern ones.

This is a great product for after rebuilding and maintaining my all aluminum block Rover engines. I use it in both my competition trail truck and my daily driver.

Little concerned my vehicle never used any oil before using the competitors brand I have used I have used a half quart of Amsoil oil now on the last seven hundred miles

Been using this in my DD/cars for the past 10+ years and never any oil issues. Good stuff.

I only trust Amsoil in all of my vehicles.

I bought this oil primarily for the ZDDP in it. The engine (67' BBC) runs cooler and quieter. I would buy this again, but probably to 20w-50 vibe the 10w-30.

I would not purchase it if I did not think it was the best product out there. thanks

I have used Amsoil products for many years in all of my vehicles and small engines. I have never had an issues. I recommend Amsoil even though it is not the cheapest but the delivery is very prompt.

RUNS COOLER< RUNS CLEANER< WHAT MORE CAN YOU SAY !

Theres nothing else out there likeit if your looking for that zinc protection

I've been using Amsoil since the early 70's. Everything from my air compressors to my boat motor. Never had one single issue with anything I ever used it on! One of my air compressor I bought in the early 70's.. I still have the very same compressor and it has NEVER let me down!! One of my service trucks had over 368,000 miles on the motor when I sold it. Never used a drop of oil between oil changes, and didn't even smoke a bit! The oil I just bought is what I use in both my cars.Will I ever use another brand of oil? NO WAY!! My motorcycle has over 322,000 miles on it and never.. NEVER used a drop of oil, never leaked, and most important, never let me down! (and no, it's not a Harley!) I've talked a lot of people into going with Amsoil over the years and they have thanked me for it many times. It's by far the best oil I have ever used and will never use anything else!
