New to me '04 E320 wagon. Oil change advice - PeachParts Mercedes-Benz Forum

ROLLGUY · #1 07-28-2018, 03:10 PM

I am a Diesel guy, but also like wagons. I just purchased an '04 E320 wagon, and need to change the oil. I did a little searching, but did not find much. Is synthetic required? If so, what weight. Also, what is the proper measurement on the dipstick tool? The W211 CDI is 130mm, and I can't assume it is the same. My ultimate plans are to use my wrecked '05 CDI as a donor to make a CDI wagon (not available in the USofA), but I want to use the car until I start the swap. I will eventually be selling the gas engine while it is still in the car and it is driveable. Thanks, Rich

My 104 motor did well on 15w50 synthetic, as it got older I switched to 15w40 C rated dino and had zero problems. Ran very strong until head gasket failed at 360K miles. Either oil will be fine, adjust viscosity though for temperature extremes.
Good luck!!?

I have heard of people using 15-40 Diesel oil in gas engines, but have never tried it. Should I use the paper oil filter or the polyester?

I used German standard (OEM brands) oil filters with both types of oil. You may like the 104 motor so much that you won't do the swap!

The '04 E320 does not have an M104 - it's a V6; I would use 5W30 or 0W30.

factory says 0w30 or 5w30 mobil 1 euro synthetic. that was the factory fill. has been since 98. now, mb has their own oil that's cheaper that the correct mobil 1. also, you need the fleece filters as the paper filters will break down and litter the engine with broken bits of paper. good luck, chuck.

My only choice is paper or polyester made by Hengst, Mann, Mahle etc. Going by the reviews on Pelican, polyester seems to be the best choice.

Oops!!! Sorry, I was thinking '94...you are correct not a 104.

Recommend using Mobil 1 0W40. Filter material is your choice … paper filters are fine. I have never experienced a problem with them, and have used Hengst & Mann paper filters for the past 20 years. I would change oil every 7,500 miles.

0W40 Mobile 1 is acceptable. If late model Blueefficiency diesel run Mobil 1 ESP 0W30.

Castrol 0w40 is the recommended oil which meets the MB standard.

As for oil level, I can only find the C320 rwd spec which I think has the same oil pan as the E320 rwd.

Thanks for posting this. I don't know why it is so hard to find info like this. I guess everyone just relies on the oil level data collected from the sensor(s) as displayed in the service menu on the instrument cluster.

I have been running the ESP oil in my '07 Bluetec. It is not readily available at the usual places. Last time I ordered it online from Pep Boys, and picked it up at the store. I check Walmart often, and they don't stock it either.

Use C-category oil in vintage gasoline engines with sliding surface valve trains. Current S-categories have less anti-wear additive due to "roller everything" valve trains, and many cannot pass the tougher C-category wear tests.

M112 has roller everything.
