ZDDP oil additive
I called C&G Ford Parts to purchase ZDDP for my Coupe's winter oil change.
They said it is no longer on the market. Any ideas/suggestions? |

Re: ZDDP oil additive
It's still "on the market". Order it from somewhere else. Ebay, Jegs, Summit, Amazon,

Re: ZDDP oil additive
Use an oil with enough already in it?

Re: ZDDP oil additive

Re: ZDDP oil additive
With the low valve spring pressure the stock flatheads have, any currently available motor oil with a valid API rating has enough zinc. If you are still worried about the zinc content. any name brand oil with a "50" in the weight has more than enough zinc in it for even the highest valve spring pressures. I currently run Mobil 1 15-50 in the hemi in my race car with an Engle roller tappet cam that has dual springs with no problems for the last 25 years.
To make along story short, guys with stock flatheads don't need to worry about zinc as long as you use any commonly available API-rated oil. Just don't use non-detergent. |

Re: ZDDP oil additive
Been using any regular oil for 25 years in mine. Whatever is on sale. No extra ZDDP needed.

Re: ZDDP oil additive
Sometimes the xtra additive clashes with the original oils additive packaging and you end up with something less suited for the use

I will repeat, any currently available oil with a valid automotive API rating is more than sufficient for a stock flathead just as it comes out of the bottle. |

Re: ZDDP oil additive
I am running a higher lift cam and Zephyr valve springs, so I feel more comfortable with more zinc than regular API oil. My solution: one quart of Valvoline TR1 racing oil for the zinc, three quarts of any good API oil for the detergent, and a pint of Marvel Mystery Oil because every flathead guru I have ever known says it works.
