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.

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.
