Sounds to me like biodiesel is on the way to becoming a superior fuel if not for any other reason than by default.

Tips for Diesel Owners
Diesel Fuel In the '90s
Diesel fuel quality is declining throughout the world, and we expect this trend to continue. In fact, a recent survey suggests that 70% of diesel fuel sold at service stations does not meet the Society of Automotive Engineers' (SAE) standard for diesel fuel lubricity. The three leading factors affecting fuel are:
- Crude oil sources
- Refining techniques, and
- Blending techniques ..."



I have been saying this for some time now. I always use Lucas Fuel treatment and Diesel Kleen in my car. I get MUCH better milage ~4-5mpg than when I do without them.

I had one if their water separators installed, the filter fell off a few times, it's now bypassed.

my '83 300D is totally stock . . . nothing but original (except for a few replacement parts here and there, but basically OEM setup). What is available the fuel department?

While this was true to a point for a while, it was a function of allowable sulfur and how refiners aligned blend pools and stocks to maximize profit. With ULSD, fuel quality has increased. The reason why is that the aromatic-bound sulfurs, generally benzothiophene type molecules, are very difficult to process.

We use hydrodesulfurization to upgrade diesel cut fuel stocks to be ultra-low sulfur. This involves high temperature and high pressure hydrogen being reacted. The issue is that the reaction is not selective to the sulfur species, and so the reaction tends to open aromatic rings and force reconstruction of the compounds before the sulfur is accessible and reacted.

The byproduct is a better fuel with less aromatics (an issue for seal swell and lubricity though), and higher cetane.

You can save a whole bunch of $$ by using 2-stroke outboard motor oil instead of the Lucas (half the amount of Lucas on my N-14), same amount of oz. on my MBZ, and it's only missing the injector cleaner, which is covered by the diesel kleen. 2-stroke motor oil IS an upper cylinder lubricant, as 2-stroke engines don't have oil pumps, so, the lubrication is provided in the fuel. Lucas fuel treatment is an upper cylinder lubricant, with injector cleaner thrown in. On my big truck, I found I only needed a quart per 150 gal tank (I have 2 of them), whereas with the LUcas, I had to throw in the entire gallon to get the same effect. And I've even used the 2-stroke stuff on a long trip in my Honda CRV. On the way I used the Lucas gas additive, on the way back, I used the 2-stroke motor oil. I got the same results of an additional 2 mpg. Not sure how much mpg extra I get on the MBZ, but thinks it's around 3-4 mpg more . . . not bad. I just picked up 16 oz. of the Walmart brand for $2.34 for 16 oz, put 4 in the car . . . sounds quieter already!!!! I'll do the gray bottle next week after I do my oil change.

. . . and the two-stroke motor oil as an additive, which never made any claims, clearly was the cheapest solution, with definite results!!!!
