Zddp question

Posted by Icarus On 2022/9/29 9:20:39
Hello there! I've been doing a lot of reading here and elsewhere about modern oils, and the lack of ZDDP present in modern oils causing premature wear in these old flatties. My questions are this:

1) did oil in 1948 even *have* additives present? I was under the impression it was straight mineral oil.


2) would it be advisable to introduce a zddp/phosphorus additive to the oil, and if so what sort of concentration would be advisable? The stuff I bought bangs on about bringing 6qts of oil up to 3200ppm, but my gut says that's WAY too high for regular usage.

Any info would be much appreciated!
