blending in a 2005 dodge pickup

Postby sacveggieguy » Sun Mar 16, 2008 6:31 pm

My buddy wants to blend wvo and diesel 50/50 mix in his pickuo 24 valve cummins 2005. I was thinking HIH heated aux filter and possibly injector line heaters for start up. We live in Sacramento California and in the summer here its usually about 90 deg f any ideas with this setup. Or should we go full blown 2 tank diesel and wvo. Im thinking the fuel should be thin enough for sure in the summer.

Thanks Paul Sacveggieguy

On that expensive and new truck I would only do 2 tank. There hasn't been enough experimenters willing to risk their new trucks on blends to say how long it would work. And repairs would not be cheap.

Depending on how many miles and length of trips he does, a 2 tank pays for itself quickly in fuel savings compared to the cost of the 50% diesel.

From the perspective of someone who does single tank cold blending in a 20 year old Toyota truck, I agree completely with the two tank recommendation. My truck's fuel system is designed to reliably operate from the town pump all the way out to the mountains of remote Whereverstan, and run on what passes for 'diesel' all along the way. Modern N.American diesels are designed more for the urban cowboy in mind and are never expected to be away from pump fuel. Their fuel systems are quite intolerant of what passes for diesel in the rest of the world. As a result, a blend I can run in an old Toyota or Mbenz can choke a modern wonderwaggon.

i too own a 3rd gen cummins common rail truck(2003 2500 4x4), and am blending. so far i am using 4gal wvo 1/2gal rug and 30gal #2. it has no smoke i mean none. by summer i am going to 8gal wvo 1/2gal rug and 26gal #2. i drive a lot, maby 200-300 miles a day, 4 days a week. i started this about 4 months ago. it has been down to 20 degrees here and no trouble. i park in a heated shop (60degrees). when i start up in the morning i drive at least 2 hours before stopping the engine. i also use 2-stroke( 1 oz to gal #2), and power service(1/3 bottle to tank).

Hello buzzinhalfdoz, and thanks for sharing with us your blending experiences. Please do keep us informed of your experiments.

It is good that you are adding RUG to your blend, because you may find as you increase your percentage of VO you will need to increase the percentage of some light solvent, such as kerosene or gasoline, because remember your engine was designed to burn diesel fuel, and vegetable oil is about 10 times more viscous as #2 diesel, so you will need something to compensate for the increased viscosity of your VO blend. I tend to keep a 20/80 RUG/VO blend relationship in my vehicle.

Also, on the 2-stroke oil, while I am sure it is wise to add such an oil when running 100% ULSD, when blending with VO I would think there would be no reason to add more oil.

Welcome to the forums.

That comes out to 11% VO (4/34.5) which contradicts your signature which says 25%. That low of an amount is probably OK, but most people aren't happy with that low %. Let us know how it goes long term.
