is this good for modern cars? whats zddp for

Answers one and two are correct. Older engines (classic cars for the most part) with older style tappets. This is an oil additive. Has nothing to to with fuel system ant Cats. nor is their any such precaution from the manufacturer.

Can you use it with syntetic oil?

Yes, Rislone is compatible with and works with all petroleum-based motor oils including conventional, high mileage and synthetic formulas.Eric

Can you use this in atv engines?

Yes..... It is compatible with all motor oils..... and engines..... Use an appropriate amount... Smaller engines of course wouldn't need the entire bottle at once.

How much zinc is in this? The back of the bottle does not tell you the numbers only oil dilutions directions.

Its enough zinc to protect your engine from excessive friction, for one oil cycle or 3000 miles.
