Which motor oil has the most ZDDP?
Mobil 1™ FS 0W-40 oil already contains a higher level of ZDDP (1,000 ppm) that could benefit your flat tappet engine.
What motor oils have ZDDP in them?
ZDDP is a zinc dialkyl dithiophosphate compound found in Castrol motor oil. Oil additives such as this provide better anti-wear protection for your engine, especially the camshaft and lifters, which are prone to wear.
Does full synthetic oil have zinc?
All the motor oil you put in your car has some zinc, but typically very low levels. If you are using mineral-based oil, ZDDP is in it, while synthetic oil, which is usually preferable, includes ZDTP. The reason you have zinc in your motor oil is to protect the camshaft.
Does Marvel Mystery oil have zinc in it?

How much zinc do old engines need?

But, if you add the correct amount of ZDDP to an oil, you combat abrasive wear and very little wear happens.
Is Rotella T4 high in zinc?
For classic car applications, the guys at Shell often recommend Rotella, and although it’s thought of as a diesel engine oil, its high-zinc formulation that’s made to fight scuffing on metal-to-metal contact is just what older engines need.
Does Rotella T6 have ZDDP?
When Rotella T6 was revised for the API specification (for use in spark ignition engines), its zinc levels were effectively reduced. Higher (content) zinc additives (ZDDP) are required for flat tappet engines and cartridge bearings, which in previous formulations Rotella T6 had desirable levels of zinc (ZDDP).
