Well, I have long said that a system is missing from diesel engines.......... an electrical ignitioni source ! ( not counting the glow plugs ) .

Shame an engine has to get buy with just 'compression that depends on engine condtion' and cmpressing the air in the cylinder until it's hot enough so that when fuel is spayed into that hot air, it ignites.

AND,.........so much depends on the conditioni of the engine itself. in a spark ingnitioin engien the engine can be half worn out and things are fine, fuel ingition happens because there is a nice system there just for that purpose - i.e ............the 'spark plugs' ( whatever those are )

The type of diesel fuel addtive that i recomend............and i say you MUST use a fuel additive in pump diesel fuel.......... I say get the one that says 'rfeducs smoking, improves power, and improves combustion." I can very, very clearly tell when a VW diesel engien in a vanagon does not have an adidtive in it - the combustion is less smooth.

pesonally...........i recognize rough/broad 3 catagoesi of diesel fuel addtives - the reduces smoking improves power kind. the cetain improver kind, and the anti-gel kind.........( and by golly, I'll have to add that onto the list of about 16 disadvantages of diesels..........and I have exactly FOUR advantages i can think of about them - those would be 1. better fuel millage than gasoline 2. further range for a given size fuel tank 3. ability to run alternative fuels like bio and veggie or even cooking oil ( granted, a BIG one there ! .......i do own 3 diesel engines ) 4. less fire danger - also a biggie, especially in boats.

all the rest of the 'features' ...............all downsides. if anyone can think of another advantage to diesels, please do say ! And personally.......... I go for the 'reduces smoking, improves power, improves combustion' type additive.

Here's one I'm waiting to try - bought it at a bulk fuel and oil supplier place : Brand is 'Penray'. says 'Year round, Fuel Prep, diesel fuel conditioner." Keeps Engines running smooth. Biodiesel and ULSD compliant. treats up to 50 gallons.

on the back of the bottle in fine print is says : Increases mileage. Improves Cetane ( but...........THANK YOU to whomever posted the link - it says there, a higher cetane than a engine needs or is designed for is not a good thing ) 'Eliminates and controls Bactgerial & fungal growth in diesel fuel" 'Prevents plugging of injectors, filters and lines" 'Eliminates tank/fuel system corrosion" "Reduces NOx"

MUST be good stuff ! scott turbovans
