when you find the grade, buy your own and give it to the garage.
Or the Chances are they will use their own bulk oil which will probably be 10w30.
Many modern diesels, especially if they have a DPF, need specific oil.....and using the wrong one can damage the DPF
LOL Wouldn't call a 1990 208D a Modern Diesel!
Yes - it is the OM601 engine. I was expecting it to say W40 in the book, but it listed both and talked about different ambient temps and stuff, non of which made much sense to me if I am honest! lol
Which Oil do I ask for in a Mercedes 208D - the manual sates W30 OR W40 and the garage say they use manufacturers recommendation. So I am confused

W40 will be a summer grade.....a bit more viscous when cold but thinning when hot.
W30will be winter grade....a bit thinner to aid cold weather cranking and overall colder conditions.
It was me, I'd use a 0W40, or 10W40, if they allow 30 or 40 grades. The 40 will reduce oil loss on an older engine. The W rating means it stays thin when cold, so offers cold start protection.
The main thing to check is the oil base stock. I'd always use fully synthetic, but would check compatibility with the particular engine first. Also, on older vehicles, check if the engine had flat tappet cams. If so, add ZDDPlus to the oil as well, as modern oils aren't allowed to have any, and your camshaft will soon be wrecked without it. It is banned from modern spec oils because it kills catalytic converters.
It is a good idea to buy the oil yourself. :thumb:

OddSocks;1025689 No idea what a flat tappet cam is or how I would go about researching this on my old merc..... [/QUOTE said:It looks like it has reasonable hydraulic lifters and should be OK, but I'm not quite sure.
