          About 3000+ on rebuild and I drive only when weather is
          cool (max in the 80s). Oil pressure range after warm-up
          is 25 at idle upto 60+ cruising with a high volumn oil pump.
          I take oil seriously.
          Franco, what can you tell us about your high volume oil pump???

            Would you be so kind as to enlighten the rest of us as to a little more about Royal Purple and its benefits??

            Am about to post the results of the survey...

            thanks!

                Hi guys, i know this is already an old thread, but would like to know if you guys know MOTUL Classic 20W50 oil. It seems to be made for cars from 50īs to 80īs, but i canīt find a thing regarding the ZDDP level.
                Sofar also couldnīt find any additive with ZDDP.

                    Thanks Ray. The Motul sold here comes in a bit different package and doesnīt show anything regarding the high zinc contents. It is specially formulated for 50-80 cars, so most probably should be right. Just send a message to Motul Brazil to be sure its the right stuff. ZDDP additive i canīt find anywhere overhere.
