Got an S&S crate motor for the Harley and the Indy put in some Amsoil 20W50 V-twin.
went down the rabbit hole looking at this and other Amsoil products and saw they make a High ZDDP oil called Amzoil Z-Rod, synthetic and specified for flat tappet engines. Anyone here have any experience running it in our engines?? 
Amsoil_20W50.pdf ( 213.73k )
Number of downloads: 47Kind of expensive, But for what the crate motor cost, its a small price. |

Thanks for posting that!
That is the lowest recommended drain interval I've seen on an Amsoil product. A good friend is a dealer and he had 24 Blackstone oil analysis done to compare Amsoil products to Castrol GTX oil. Amsoil was extremely impressive! At 20k all three cars (Fiero V6, Pontiac GXP V8, Prius) came back "oil fine, continue to use" from Blackstone. Castrol OK at 7.5K and gone by 10K. He wanted to test their claim of 15K and Amsoil kicked ass! They are too expensive, and they are semi "multi-level", but actual testing proved their claims 5k over... Going to have to gets some from my friend. |
