The reason why I'm asking is because it is a fairly inexpensive oil that I'd like to use on my 71 280SL. AFAIK the green Brad Penn stuff has high zinc levels but I don't think that 15W40 is green. Right now I'm using Valvoline VR1 20W50 Racing oil on the 280SL and it is around $4.50 per quart as opposed the the Brad Penn 15W40 for under $3 per quart. The valvoline stuff clearly states high levels of zinc on the container but doesn't specify an amount.

So far so good but all I have to go on is the pressure at idle - which looks better than before - but there are so many variables it's not a great gauge. I'll run a test on it before long and see what the ZDDP levels look like after ~2000 miles or so. I think the cost to have 2 gallons plus shipping (Pa to Va) to my door was around $75.

I like using the 15w50 in the summer as it leaks/is consumed a bit more slowly. Anyway today doing the change I learned 2 things, #1 oil filters from Car Quest are NOT as good as from Rusty - the o ring is too big and won't seal the canister, fortunately I had a spare. I though I had a filter from Rusty, turns out it was for a 601 #2 M1 15w50 is no longer diesel rated, SM only. I had an older bottle that was CF that was probably bought last year (post facelift, so recent). I dunno if the manufacturer has to continuously pay for certification and they decided they weren't selling enough to diesel owners or what but I'll run a short change on this one (I usually go 7,000 on the 240D, I'll go down to 5 or so) and switch back to 5w40 which I hope still has a C certification, if not it maybe be Amsoil although my local Car Quest has Royal Purple... -Curt _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
