Did you ever try to start a 616 at 0F? With 15w40 conventional oil it ain't gonna happen, 10w40 maybe. M1 5w40 is no big issue...
When I first got my '83 240D it leaked/consumed a little oil using M1 but nothing exciting. Then my brother in law gave me a gift card for an oil change which was conventional oil. After that it lost a quart every 1000 miles or so for the next 50,000 miles. I never did determine exactly where it was leaking from. Thats made me a little gun shy about switching back and forth between conventional and synthetic. Its irrational, my 240D was probably due to start leaking anyway... My current '78 240D is great, its leaking/consuming around a quart in 2,000 miles and improving with each oil change. M1 is cleaning/rejuvenating the seals (apparently) and making the leaks less. Oh and I suspect the snowmobiling in Georgia sucks. -Curt Date: Sat, 16 Jul 2011 18:08:42 +0000 (UTC) From: roger...@comcast.net To: mercedes@okiebenz.com Subject: Re: [MBZ] Delvac sale at Oreally?

No. You've got to remember there are other places where it gets cold in the winter. Living in New England Mobil 1 is your best friend when it comes to cold weather starts, even 15w50 is... But a little of each in the freezer and see which one pours better, do you want to depend on the honey thick stuff to get to the bearings in a cold start? -Curt>>>>> Curt, Sorry that anyone lives in that God Awful cold of the Northern climes. What did you do before Mobil 1? I guess that's why people used to ride horses as apparently no engine would survive in cold climates without Mobil 1 synthetic :-)) Gee, when I lived in the North, I used 10W40 from Valvoline and never had problems. Of course, I didn't take the head off my engine once a month to be sure there wasn't any wear. I know what you are saying about cold starts. So, move South like I did and you won't have that worry anymore. There's still room!!! Or at least until we get annexed by Mexico.
