2000 E320 oil question
I have talked with different people who have used regular oil and have over 200K miles on them and have NEVER had a problem, as well as those who have used synthetic oil and not had problems.
Can any of you please enlighten me?
As far as oil, the main issue is whether you are going to use the built-in FSS (Flexible Service System) to determine when you do an oil change. MB recommends specific synthetic oils and special fleece media filters when changing according to FSS (usually >10K or 1 yr). If you use regular oil and paper media filters, you need to change more frequently maybe 3K-4K. Do the math and you'll find FSS is probably cheaper.
Early W210's had serious problems with oil sludge because people used regular oil and then used the FSS to determine the oil change interval.
The computer in the car can adjust engine operating parameters to burn regular gas so you may not notice the difference during normal driving but your gas mileage and performance will be poorer. Again not any likely cost benefit.
I would suggest operating the car as it was intended by the manufacturer which is spelled out in the Owners Manual. Many owners of these cars expect to get 250K or more. They are built to last much longer than most cars providing you treat them correctly.
Good luck.

MB spec oil is Synthetic, Mobil 1 0w40, Castrol Syntec European Formula and some others. This oil, along with the proper fleece oil filter can be used for 10-12k miles. I change my oil every 10k miles, always with synthetic.
Everybody on this board will recommend that you use synthetic oil. If you choose not to use synthetic oil, I'm sure you wont do any damage but then I would change the oil at around 5-6k miles tops. The yellow sludgy stuff you are seeing around the filler cap has nothing to do with the type of oil you use. That has more to do with the outside temperature and how often the car is driven to full operating temperature. It is an emulsion of water and oil from condensation in the engine. If you took a nice long drive in your car, it would be gone.

I have a recently acquired 1998 E320 100K miles. I am planning to start to do my own oil changes (suck out the dip stick). I have read that Mobil1 0w40 is the MB approved oil. My concern is that I live in Phoenix, AZ and as you know it gets extremely hot here in the summer! Given that a good portion of my daily drive is stop and go traffic is this oil still the best to use? Are there any other oil considerations/recommendations for this hot dusty environment?
Thanks

Trust me it's hotter inside your engine than it ever gets outside in Phoenix!
And I've been there in August. When changing viscosity it's the lowest temperature that matters not the highest. Mobil 1 0W-40 is okay to -25C (-13F). However, blowing dust is one conditions under which oil should be changed more frequently. I don't believe the FSS monitors for dust although the oil filter is supposed to handle it. As MM said more frequent checks of the air filter are in order. If there is a 'dusty' season and the car is parked outside a lot I would probably change my oil at the end of the 'dusty' season just as a precaution.
I posted a link to a MB document with all the fluid recommendations in a thread called "Regular Oil vs Synthetic ??" in this forum today. It lists 229.5 and 229.3 oils by brand. (Page 4)
Good luck.

In fact, a 229.3 oil is acceptable for MB prior to 2005 so you are correct as is shown in the table on page 3 of a MB doc I listed a link to in another thread.

I'll have a look for that thread and check out the MB document. For now I'm using the Mobil1 5W40 Formula M (not the ESP as I'm aware that's for diesels only) since that's what my dealer has in their bulk tank. I use oil so needed some by the quart. My dealer doesn't have it and say their supplier does not carry it (more insanity). I found a case of 6 online and ordered it. Plus it no longer even appears on the Mobil website so I guess I got some old stock. It's enough to make me tear my hair out sometimes.
Why they haven't reverted to the 0W40 is anyone's guess. I asked the parts guys and they didn't have an answer. Another dealer I am familiar with changed back to 0W40 at least a year ago.

Mobil is currently changing a lot of their product labeling on their oils and their web site is also undergoing change to reflect the new branding and that's part of the confusion.
Another part are the 229.31 and 229.51 spec oils. Both Mercedes and Mobil have wavered on their use in gasoline cars. As of today, MBUSA officially says "Diesel Only", while Mobil says thier 229.31 and .51 oils are good for both gas and diesel.
Finally....the ESP Formula M thing. FYIW that oil isn't even API rated, nor does it carry any other manufacturers ratings. So it's only "approved" as 229.31 and 229.51 making it for exclusive use on a Mercedes diesel car. However, Mobil says it's good for MB gassers too.
Frankly, I think all these European manufacturer specific ratings are a bunch of hooey reflecting ideology and corporate alliances as much as true engineering requirements.
Lastly I think you're probably right about the corporate alliances. In reality, we can probably run anything we want (brand, viscosity, dino with more frequent changes, etc.) in these MBs and would be O.K.

The reason I went with them rather than OEM was the Toyota pump was only available as new and was over $1000. The NAPA reconditioned was about $250 and the shop recommended that they put one in. Saved me money but there was the inconvenience of 3 trips to the shop for all of that.
