Ok, I goofed on my first post, it's quite obvious that I should have dropped any mention of Porsche.
My question is and was and will be which has the most ZDDP. Castrol Syntec 20w-50, Vavoline VR-1 Synthetic, or Mobile 1 V-twin 20w-50.
And, with regard to the 20w-50 V-Twin...what ill effects may it have?
Simple. And CATERHAM, I KNOW that the first number is "startup/cold."
Also, the recommendations for Porsche are for the NEW models...NOT 80's, 70's, and 60s. Unless somebody can point me to a TSB regarding a 1985 Porsche 911 3.2L using 0w-50 or 5w-50, then I'm sticking with what ohhh, every 911 mechanic I've known and every 911 owner I've known uses: 20w-50. 911 are through the 1989 model year.
To answer where I found it. Advance Auto recently (buying oil for a friends Jeep and there it was). Ordered it from NAPA a few months ago, because I prefer most NAPA stores as they are more professional (at least in FL). They have NOT replaced it with anything to my knowledge and it still shows on their web site. I think they've dropped "classic car," but wouldn't swear to it.
So, to get back on topic. I don't care about anything but 20w-50. And my question is primarily about ZDDP levels for those oils. If not, I guess I'll stick to the Castrol 20w-50 Syntec for now.
Thanks.
