Use regular oil, no need for synthetic, semi-synthetic or any blend.
Check your manual, you should use 10W40 for colder climate and 20W50 for hotter climates.

One which is changed frequently ! :thumbsup:
I use a 15w-40 with 'Active-8 anti-friction additive, but if you only want the engine to couple a couple of hundred thousand miles then Duckhams wil do okay. :surrender:

The best oil is valvoline 10-60 raicing
Really ? Why? :confused:
What makes it 'best' - and 'best' at what ? Lower friction ? Better removal of poducts of combustion ?
Can you direct us to some web sites showing the results of some quantitative tests ?
Or are you just talking crap ? :surrender:

Mobil recommends Mobil 1 0w 30. Isn't it too thin to hold up with those ol enginesy?
If you happen to live in a really cold country, have a brand new engine and it never runs hot then you'll get away with 10w30.
For an 'average' engine - just a bit worn but not too much - and in a temperate climate you'll do about right with a bottom figure of about 15. Maybe you could use a 10 in winter, but it would be like water the rest of the year. For normal running you want a top figure of around 40 or 50 if you are in a hot climate. 60 would only be necessary for competition where engines are more heavily stressed and run hotter.
With England being a temperate climate I tend to run all my cars with 15w40 all year round. If it is a really hot summer and I know I'll be doing a lot of fairly fast driving - maybe continental touring or whatever - then I'll go to 20w50, but I'd not use that in a modern engine in winter - it is too thick !
thank for ur view. how often u service ur auto-transmisson?? what types of lubs u use?
I'll change the transmission oil at about 24,000 - 25,000 miles (major service interval) which is what Mercedes recommends, though many people leave it in much longer. I just use straight ATF with no extra additives - you don't want to put a friction inhibitor in an auto box ! My preference is for Duckhams lubricants as they seem to show slightly better results in lab tests.
what elses i need to pay attention during servicing the car?
Basically it would take just far too loong to list everything. Your local friendly Mercedes stealership should be able to give you the 'official' Mercedes list of service points if you really want it.
The general idea is to replace engine oil, oil filter amd air filer every 5000 - 6000 miles and inspect anything which tends to wear a lot, like the brakes, and check ALL fluid levels. At 10,000 to 12,000 miles you need to be going right around the car lubricating everything properly - not just the big obvious things, but locks and catches, hinges and stuff like that too. I also like to replace the spark plugs at this mileage - before they start to show signs of age.
At about 24,000 - 25,000 miles you do a 'major service' which is a full replacement of ALL the fluids. This includes the brake fluid and the coolant. ALL filters should be dismantled and cleaned and/or replaced as necessary. Wheel bearings should be cleaned and re-packed with grease. Brakes should be re-lined. The rest of the major service is inspection of everything you can find. some manufacturers specify that all braking system seals and flexible hoses should be replaced at a major service too - though most suggest this is done at around 50,000 - 60,000 miles.
One of the things I do every year - which is often neglected by most people - is to go around the entire electrical system, every connection, bulb and fuse - and make sure the contacts are clean. Petroleum jelly (vaseline) is great for keeping connection weatherproof.
There is one alternative to proper servicing: wait untill something breaks down and then mend it ! That's the choice - one or the other. There is no 'third option' you either service it or it will break down - this is the only realistic guarantee you get once a car is a few years old. :thumbsup:

You are using the perfect oil for your condition. Good choice :)

15W-40 Castrol diesel oil. Actually I think all 15W-40 weight oils are diesel oils. I think Kepla has covered the topic nicely. 20W-50 if you go rip-assing around a lot, 10W-40 in colder climes. Synthetics? Well, it's your money. Your motor doesn't care.

You have a diesel engine, I assume you need 15W40 Diesel Oil.

10W-40 oils are not diesel oils as far as I know
