The best for pushrod engines

Works great in my supercharged Vette!

Necessary to maintain the 1966 396 engine in my Super Sport. Full synthetic has many added values over conventional oil especially in cars that get low mileage, irregular usage.

I use Amsoil in all my vehicles. Bought this for my 1977 Ford F-250 after the top end of the original 351M was rebuilt. Thought it would be the right choice for this classic motor. Time will tell.

Using it in my Tahoe change all my fluids expect transmission my mileage went from 14-15 to 18-19. Hope after doing transmission will go over 20.

If you dont want to wipe out cam lobes, USE THIS PRODUCT!!!!!!!!!!!!!

I bought this oil based on the fact that it has extra added Zinc for flat tappet cams generally used in hot rod motors and the fact it is known in the hobby to be excellent oil.

I use this product in my 1952 M38A1 Willy's Army Jeep The engine runs quiet and smooth with this oil

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
