jassz,

How effective Lubro-Moly Diesel Purge will be for your car depends quite directly on what you are faced with in terms of problems. If there is a problem that is being caused by mechanical/dimensional deviations from design parameters in metal (missing metal, for example) parts, Lubro-Moly is not going to be much help.

If, on the other hand, the problem is clogged prechamber orifices, clogged with the by-products of poor combustion, or low grade nozzle spray patterns caused by carbon deposits from combustion problems in an around the nozzle critical surfaces, possibly caused by poor quality fuel, or even deposits on valves or the piston rings, preventing effective seating, then Lubro-Moly Diesel Purge can be helpful. These kinds of problems are not uncommon, and there are many fuel additives/products used by those of us frequenting this site. I use RedLine's Diesel Catalyst year round, and add Power Service Winterizing product when the temps are under 30*F.

I have never used the stuff you bought, and do not speak French so I can't help much translating the French claims of the product's benefits. I could help translate the German though.

If you think you have water and algae in your tank, I second the recommendation that you drain it, clean it and then run some algae control/killing additives through the tank. If you don't address the algae problem directly it will not go away. I could cite some analogies from highschool health class but will restrain myself. Once you have the system clean, keep it that way with regular use of additives to chemically absorb water, and improve combustion. Also, learn to avoid fuel stations with slow turn over of their Diesel stock.

Good luck, Jim
