The air filter for California certified '85 diesels is a different shape than all other OM617.95 engines (so it will fit with room for the trap oxidizer and the plumbing that replaced it) and because there are relatively few California certified cars, the filters are expensive.

Re: [MBZ] Diesel Air Filter service life.
Where are you buying the filters? BAP Import Parts? When I had my 240D (123.123), I'd change the air filter after about 5000 miles. Usually a few smacks on the ground caused enough debris to fall out that I never felt bad about putting it back in. -Warren Marshall Field wrote: I am going broke buying air filters for my three 300d's.

Re: [MBZ] Diesel Air Filter service life.
You are replacing your filter way too soon at 2,500 miles, I believe that 35,000 miles is more the norm. If you really want to get scientific about when then you need to install a vacuum gauge with the pickup through the lid of your air cleaner housing. You'll notice some drop even with a new filter but the drop will become more pronounced as the filter plugs up. I believe you'll be surprised at how un-plugged a dirty looking filter is.

Re: [MBZ] Diesel Air Filter service life.
Just beat it on something, or blow it out with air. If you want to get fancy, just pull into one of the few zillion offroad specialty places in Phoenix and they shouldn't have any trouble fitting your filter with a washable pre filter. --Robert Marshall Field wrote: I am going broke buying air filters for my three 300d's.

Marshall in Phoenix Marshall, I live in Phoenix, drive mostly on paved roads, etc and get about 30,000 miles out of my air filters, sometimes tapping them on the cement if I am in there for other reasons, like replacing the rubber housing mounts. A dirty filter is more efficient at removing smaller particles than a clean filter. Do your filters turn black, as in excessive blowby, or just look dirty? If black, you may be over filling your crankcase with oil. I think most of us agree that you should never fill oil in to the full mark on the dipstick, leave it 1/2 to 1 quart below full.
