Saw this regarding GDiesel, anyone else heard anything on it? Seems almost too good to be true, but the US military doesn't have doubts so maybe I shouldn't... Very curious to hear a knowledgeable perspective on this. If a 2009 ML350 bluetec went from 24 to 36mpg, I can only imagine the benefit on my 335D

Interesting and certainly a positive step for the diesel community. While the apparent improvements in efficiency are nice, I would be curious to see if this process has any affect on the lubricity properties of the diesel fuel and engine hp output.

Send a message via Skype™ to koreez88
I'm more curious if BMW would allow us to fill up with that.

Sounds like an exciting development. If it has such a low sulfur content I too would be concerned about lubricity, but the increase in mpg is very enticing. Even a modest 10% increase means I'd be getting 37 mpg in mixed driving.

the smart part of their process is when they talk about making hydro carbon chains of more similar and consistent size. The black smoke, smell, and bad fuel milage comes from improper or incomplete combustion.

If for example, you had a range of hydrocarbon chain from 6-12 links long, the 6,7,8,9 link long hydrocarbons would burn completely, and the 10,11,12 wouldn't have time to burn completely. This is why when diesel vehicles switch to propane (a much shorter hydrocarbon chain) then you have fewer emissions. BUT, by having too few hydro-carbons, then you begin to have much less energy going in to the combustion chamber therefore require more overall fuel.
Gdiesel takes a smart approach by basically increasing the surface area of the hydrocarbon chains while still keeping a long carbon hydro-carbon chain, so the energy stays.

How this produces IN SOME CASES 50% BETTER FUEL MILEAGE?

This is of course a marketing piece. Take it for what it is.

Maybe if you use Gdiesel with magnets and a tornado intake you car will not use any fuel what so ever.

I am wondering if there is someone that lives in Reno, where this GDiesel is available, can tell us their expirence with using it? I am very curious and want to try it.
