Good product, good price.
I run this in my hot rod truck running a small block ford 347ci stroker motor. It sticks to parts like honey and keeps things well lubed. This is a quality motor oil that is meant for our hot rod motors especially for those running flat tappet cams it has the extra zinc needed. I am running a roller cam in this motor but I still run high zinc oil as it's recommended. Came quickly and you can't beat the price.

Best oil for small engines
Old style oils had zinc added to be a better lubricant for the old style bearings. Lawn mowers and small engines still gave that style bearing. This oil has the added components to keep small engines running better longer..

Great choice for older vehicles
High zinc oil is recommended for older vehicles with flat tappet valve lifters. Using in 97 jeep 4.0 engine. Runs quiet and smooth in S.C. summer heat. Do not add any other zinc additives when using this oil as too much is not advisable.
