The S series just keep going up and all are compatible. With the C series it doesn't work that way. The issue with Diesels is the pressures, temperatures and contaminations. Combine that with a Turbo and you have to be extra careful. The reason 10w40 is a problem is the VI improvers in 10w40 specifically break down on the rings of a Diesel and will score the cylinders. I don't fully understand why it's not a problem with other weights, or if it is still an issue. Most Diesel manuals say don't use 10w40 and I don't. :) With Diesels I've found that regular oil changes are most important. With a fuel injected gas engine it's easy to go 15,000 to 25,000 miles or more on an oil change without a worry using amsoil. On my Diesels the longest I've been able to go is about 7,000 or 8,000 miles. MOst of my Diesels leaked or used oil before I got 'em... never had a fresh one to test out really. :) If I were running dino oil in a Diesel, and Rotello and Delo are both excellent dino oils to use in a Diesel, I'd probably change around 3,000 miles. With amsoil 15w40 I typically shoot for around 7,500 miles. I know the newer MB Diesels use synthetic and spec it at 10,000 miles. Even though I know amsoil is good, I'd not go that long, turbo's are just too fussy to risk. :) All this talk of oil reminds me that my 83 J10 stepside is leaking oil out the valve cover like the Valdez... need to get a new valve cover for it... the stock plastic one isn't working out too well. :) john - ------------------------------------------------------ http://www.WAGONEERS.com/ http://www.wagoneers.com/think-about-this.html Snohomish, WA - where Jeeps don't rust, they mold... - ------------------------------------------------------- ------------------------------ Date: Mon, 17 Jul 2000 16:54:51 -0700 From: john Subject: Operating Temperature - '83 240D Date: 17 Jul 00 16:45:28 PDT From: Patty Thompson To: diesel-benz-digest-at-digest.net Subject: Operating Temperature - '83 240D I have a Black '83 240D which I adore, but she runs a little warm - over the 80 degree celsius it's supposed to.

HELP! Thanks, Patty Thompson ================================== I'm forwarding this to the list... majordumbo says you're not a member, but that's ok... details on how to get on the list below. :) Some things to look at: 1) thermostat 2) water pump (check weep hole, feel for free play) 3) fan clutch (is it tight? does it wobble?) 4) is there REALLY a problem, or is your sending unit lying to you? Because the gauge is jumping around you may have a loose connection on the sending unit or a bad ground to the dash... or a broken wire... Or, the T-stat, water pump or fan is on the "fritz"... ;) john ============================================================================ ========== To subscribe to a list on digest.net, EMAIL majordomo-at-digest.net, no subject needed, in the body: subscribe [ fsj | xj | diesel-benz ] end (note: select only one of the options in the brackets) You will need to reply to an authentication message.

It has M14 thread and switches at 100C. I wish to replace this with a similar switch that flips at a lower temperature. Does anybody know of an M14 thread temperature switch for ANY car that flips at 70-90 celsius? What about different threads, assuming I can get an adaptor. I know that mercedes does not have anything. VDO may, I am pursuing that line also. What about VW, Saab, BMW or whatever else? Thanks in advance, SDB ------------------------------ Date: Wed, 19 Jul 2000 00:25:18 EDT From: Peloquinrl-at-aol.com Subject: Bypass oil filters Great info on the oil topic. Can someone explain how a bypass oil filter works and how it would be installed on a 240D/300D?
