rotella 15-40 smells good, too.

it is all we used on the peterbuilt trucks i worked on in the late 90's. we'd go 10-12k on changes.(midwest to west coast 3 times) with huge filters, of course.

I am going to try mobil 1 0-40 for winter.

I think we are splitting hairs here. Don't You?
Unless you are considering long drain intervals like in the commercial trucking industry which utilize a far more efficient oil filter system than we have in our MB's, if not then it could be cracked from camel piss as long as it meets the API rating that Mercedes requires of US oil which is CG-4 or CF-4. They all meet the shear, heat, and soot requirements for diesels.

There are plastics that are made utilizing cracked hemp oils...does it make the plastic any less synthetic?

Hi Rotella users report having so

me of he cleaner engines,but i get real good results with Redline diesel 15w40 or Amsoil 15w40 diesel,It purrs try it...

I read a very comprehensive report a few years ago looking at cranking speed with regular vs. synthetic oil. There was a big difference in favor of synthetic. This could make a difference in starting a diesel engine in cold weather.

I like M1 5W40, it has better diesel specs than the 0W40, and it cranks over very well in the cold:

My data is from mid 80's, Agricultural Engineering. Most of the major engine Mfg. attended the annual convention and all said that the then 'modern' oils where far better than the past oils except paraffin-based oils. Granted this includes gasoline burners. But the point that struck me is that all oils where only 1/3rd oil & the rest was additives! So the synthetic vs. regular oil question is a bit gray or blurry.
If you talk to Cat, Cummings, Mack, ... they all say use rated oil suited to the climate, check level often and FILTER, FILTER, FILTER.
I like Mobile 1 in pricey car engines and manual trany, but for my WVO MB Volks-Panzer, Rotilla. Diesel oil needs a more aggressive cleaning action than gasser oil.

G'mornin' Folks,

Back when I woeked in the real world, before I retired, I was Chief Engineer on Merchant Ships. I used to order my lube oil by the ton!! Like 30 - 50 tons at a clip....would take it pumped from a barge, or from 18 wheel tank trucks, sometimes received it big square steel tanks.

I have several books in my personal library dealing with lubrication of internal combustion engines. I have attended several classes and seminars over the years...before retirement.....

First, lube oil, is blended and has additive packages...use the proper service rated oil for your particular application....any brand should be fine as long as it has the specific rating that you require.

Synthetic vs Petrolium based oils.....I had an oil representative present aboard a ship that I was aboard, when we were directed by the "company" (ship's owners) to switch to synthetic oil as a test.....bear in mind that I sent lube oil samples to a lab for analysis on a quarterly basis.....the "company was exploring the cost of extended oil changes with synthetic vs. the in place oil change schedule......we also had centrifuges, and could "purify" (remove particulate matter) oil from most of our larger machinery. The lube oil rep was concerned that the synthetic oil would remove existing sludges and varnish buildups and cause way more problems for us....like plugging of internal oil spray nozzles ans such....these engines were around 15 years old at that time (as I remember). What I learned from that experience was, if you have been running petrolium based oils for years, it's best not to switch to pure synthetic oils. Therefore I use synthetic oils in brand new vehicles/machinery, and use petrolium based lubes in older (used) engines (when I don't have access to a good machinery history).

Note: Around the commercial fishing crowd you have a lot of Delo 400 fans, where I prefer Rotella-T......but I think that they are nearly identical, except for the color of the container.

Also: I use Valvoline "High Mileage" for "older engines with over 75,000 miles" in my Ford F-150, 300 Six, and in my old Gravely's......

Note II: There is a device that the Germans use on Industrial applications, sort of like a mini centrifuge....powered by oil pressure. I have seen them on MAK, MAN, and KHD (Deutz) engines as well as fitted to a Zepplin Caterpillar!! I think that they are manufactured by Mann & Hummell, made from aluminum alloy, they look like a small dome externally, and inside is a precision/balanced rotating cylinder....inside of the cylinder, which screws apart....there is a paper liner, this serves to make cleaning easier.....you should see the crud that these things remove from a diesel engine!!!!

Note III: I was surprised to find difficulty in locating MB recommended fluids and greases....even the local MB dealership didn't have ready access to info for older Benzes.....I was specifically inquiring in regard to brake fluid and antifreeze, as well as power steering fluid.....didn't get much info, Brake fluid, either a particular MB part #, or any good grade of Dot-4.......Antifreeze, MB part #, or any good quality anti corrosion antifreeze, when asked about the newer antifreezes that won't poison your dog the service manager said "should be ok"....Power steering fluid, MB part # only reference that he had.....perhaps MB wants us to buy it's products only because they can make way more money by having stuff bottled in their brand name!!!

Thanks Guys,
SB

Thats what's been in my 603 since I have owned it, best stuff on the market as far as I'm concerned.

amsoil sythetic 15w40, whole new purr is right..

I always used Delo-400 because it seemed to be what my 300CD liked the most...

Gurkha · #28 10-06-2006, 09:35 AM

At the point of sounding redundant, Delo 400, Delvac Super/MX or Delvac-I if you have lots of money and intend to do extreme condition driving.

aklim · #29 10-06-2006, 10:36 AM

Delvac 1 is their diesel rated oil. I use it myself and noticed that there was a mileage increase when it came to oil changes. My oil life meter even let it go over 13000 once. never got that good with dino oil

WD8CDH · #30 10-06-2006, 10:38 AM

I used to use Rotella 15W40 in the summer and Rotella 10W30 in the winter but I can't find the 10W30 any more so I went to Mobile 5000 10W30 since it was also rated CF. CF is a higher rating than was available when my 300 was built so I figure it is good enough until I can find either a CI-4 rated 10W30 or go with a 5W40 CI-4 rated synthetic.

I can tell you that back in the 80's, just the simple change from a 15W40 dino oil to a 10W30 dino oil in the winter made a world of differance in cold starting a diesel at below freezing.
