Im gonna do an oil change soon and was wondering If I can put in Mobil 1 Synthetic? Or is it a bad idea. I think I have some type of castrol in their now. What weight oil should I get and how many quarts to fully fill it up?

Any help would be appreciated thanks.

You can use any oil that is rated for diesel and the recomended weight is 15W40. You need the diesel rating because of the soot that blows by the ring. Diesel oil controls this better.

M1 would be excellent in your diesel provided there are no bad leaks. As noted above you must use a CH rated oil and synthetic is both SJ and CH (diesel) rated.

O ok. Thanks for the info. How many quarts does it take to fully fill it up?

Should take 7 to 7.5 quarts, also assuming you will replace the oil filter at each oil change. Shell Delvac is another good choice.[:)]

Put six quarts in first and drive it a round for a while then check the dip. You may have as much as a quart of oil in the galleries, sump, and oil lines – you don’t want over fill. 6.5 quarts will get my oil level just below the top notch on the dipstick after an oil and filter change. It’s much easier to add oil after putting six quarts in first than be forced to let oil out if you over fill.

First oil change, I just put in 4 quarts of 20-50 and 3 quarts of 10-30. All mobil 1 synthetic. I'm not reccomending this mix, its just what I had on hand. My car supposedly had 116k before I bought it, but really, thats just where the odometer stopped.

Result: Faster startup, approx the same amount of nailing during startup/warmup, no reduction in engine temp.

I am considering changing only the oil filter in the very near future.

Cheers,
Robert

Shell Delvac? I thought that was Mobil Delvac?

I might also use that Delvac soon, I'm almost due. The four Mann filters just arrived today. Is it good to mix oil brands (same specs)?

I have when low and nothing else is available. I change the oil right after, it’s usually due by then anyway. I now keep oil in the trunk for such events. There’s a school of thought that the different brands’ additives may ‘clash’ and neutralize, leaving the engine unprotected. You can put synthetic and dino in together with no problem, but I fail to see the point.

I heard that Mobil Delvac and just Mobil Synthetic oil are the same for diesels. Somebody might correct me on that though.

Mann
Bosch
Hengst

These are the filters for your car. On my car it has a "Mann" sticker on the oil filter casing, so I get Mann. Do NOT get the Fram ones, or any other poor quality ones.

www.germanstar.net
www.performanceproducts.com
www.autohausaz.com
www.mercedessource.com

Sites that sell the filters (not all have the 3 mentioned). Hope that helps

I can't find any Mann oil filters at any local auto place like autozone or kragen. Any other brand? O and I dont think this got answered, but is their a specific size to the filter?

Dunno if there's a specific size, but it's suited for the cars.

Replace any asterisk (*) with "M B Z . O R G" without the spaces. In order: Mann, Hengst, Bosch





On my Mann filter box, it says:

Fiaam FB 1517A
Fram CH2930
Hengst E196HND03
Knecht/Mahle OX 78D
Purflux L459
Tecnocar 0152

I guess these are the other alternate brands and models for the same filter type. This Mann filter is is model# PF 1055 if you happen to chance upon a shop that has these. Hieu Le's shop I referred you to has Mann filters but I'm not sure if he has these for W123 turbodiesels.
