C350 oil and fuel filter recommendations

This has been discussed many times. If you use the correct specification oil and filters then the normal manufacturer specified oil change intervals are not an issue regarding engine life unless you are operating the vehicle in very arduous conditions.

Probably true on most MB engines , just don't tell it to the folk with wet belt engines an those blessed with certain Ingenium engines :eek:
 
Probably true but the oil that comes out of mine every 10k is like water, guess it's diluted by the diesel ??

No harm doing it at 10k or 15k as you say.

I have one on 220k and one on 155k

What are the issues with mann filters, can't say I have noticed - actually just bought one for an oil change this coming w/e

I think they fail early regardless!
 
Personally I think most engines WILL benefit from shortening up the OCI bit.
Do you honestly think that they really want their cars to last forever?
And of course you and me are a small part of the business.... they are more concerned about the massive fleet market which is all important. The saving between an oil change every (for example) 20,000 miles and every 10,000 miles could be all it takes to swing deals their way. It could mean quite a saving for a fleet manager running several hundred cars.
ALFA all but admitted they had done this when they seriously reduced OCI and miles and nearly halved cambelt change mileage on the 916/156 ranges, after they realised they had pushed it too far in the hunt for fleet business. At the end is the day changing the oil more frequently can only do good... and it CERTAINLY can't hurt your engine....just maybe your wallet a bit!
 
Oil generally starts to loose its viscosity around the 5k mark, I change mine every 4K, but that’s just habit and I only do 4K per year, the engine internals may be fine, but the turbo spinning on old 10k plus oil, isn’t ideal, oils cheap, metal ain’t, as they say. 😁
 
The engine doesn't know how many miles the car travelled... in fact, other than in motorcars, all other ICE engines that I had experience with, had their maintenance schedule in hours, not miles or kilometres or knots. A 10,000 or 15,000 miles oil change interval is a guesstimate at best. MB did have 'flexible ASIST' up to 2007, which took into account many things including how many times the engine was started etc, but they got rid of it because it gave fleet managers a headache when they couldn't predict or plan servicing in advance. The most accurate way of servicing an ICE engine is by periodically taking oil samples and having them analysed in a lab. BTW, from memory, when Mobil-1 was first introduced (eighties?), Mobil claimed thar it only needs to be changed every 25,000 miles.

I can remember Austin Rover, or whatever they were called that year, doing something similar with the Rover SD1 when the facelift / Series 2 was launched in 1982. There were no mechanical changes or changes to the oil or filter specifications, however, the recommended service schedule was changed from 6,000 to 12,000 miles. Adverts at the time stated that it was to reduce service costs; there was no other reason or rationale.

Hmm....certainly does not look it.....
Last oil I saw like that had been in a Massey 135 for about 10 years on the farm my dad does a bit at!!! Still ran fine though even though it should be changed every 100 hours of use!!! Like most tractor's it has an hours gauge in place of a milometer

Sounnds good to me. My son and I - Diesel 201 and petrol 124 - change engine oil and filter at 10,000 Kms, or about 6,000 miles. Usually with 5W30 MB spec oil and filters direct from MB. All well so far, touch wood. By the way, my MB filters are only 8€ each so no need to seek aftermarket brands.

€8 for MB OE? Which country mate? It’s €35 here in Greece.

Ok, 10000 miles at a speed of 33mph is 303 hours of engine use.
I have no idea if that is alot, normal, or nothing at all ?
