I could not help but notice this:

For Sale:$400 81 VW Rabbit 1.6 na running on WVO with some RUG blend, needs injection pump to run best.

Care to comment?

Yeah i'd give 200 bux if the body is not in rough shape.
Where is it?
Considering its an 81 it could be an old age or high mileage problem.
With the few facts that are known i would say that it may be streching it a bit to say that the blend did the pump in.

I thought the problem with blends was with carbon in the cylinders not the IP?

Cant buy much for $400 these days .

Who would know from that discription..its poor running probably has nothing to do with the injector pump..in my personal experience with VW diesels ive only managed to kill one pump in 15 years and that was from pumping it full of water..i just couldnt get it all out after that and finally gave up and swaped it out

Well, If you're trolling, I'll bite.

I doubt the blend did in the IP, unless the owner went a little overboard and was running a 50/50 mix. You never know.

As for myself, I'm sneaking up on 25,000 blend miles. This weekend, I'll replace the two fuel filters for the first time since I began blending. Seems like blends clog filters less.

1984 MB 300D, 420K, original engine and trans. V80 Blend (80% vegetable/20% petroleum) since 400K.?

maybe with 420k you haven't got enough ring lands left for the coke to hold on to???

Can this 80% WVO/20% RUG work in cool climates? Would I still want to replace the fuel lines using a blend like this? Why blend with RUG and not diesel?

Still learning....

Blending can be done in cool climats, you just have to shift the blend based on the seasonal temps.

The Rabbit is sold, it belonged to Charles B on the forums. He said the IP was weak, the car would start and run well, but would not get up over 55mph. I'm not even sure that's an IP issue, but hey, I didn't own the car so I never got to analyze it.

The reason for blending with RUG is threefold. #1, RUG is thinner than diesel so it will thin the mix more per gallon added than diesel. 10% RUG will thin as much as 15-20% DIESEL, so it's cheaper. #2, RUG will help dissolve waxes and fats a little better than diesel or kero. #3. diesel contains paraffins and (very rarely) will drop these waxes out of suspension when mixed with WVO. Seems like it rarly happens, but when it does there's a bunch of white snot flakes floating around in your mix clogging up everything. Bad.

That said, I DO use kero instead of RUG, but that's because I get the kero for free, almost, and I have a heated system so I don't want to boil the RUG (vapor lock)

So blending ... say 80% WVO (dewatered and filtered to 2-3 micron I'm assuming) and 20% RUG will work well in engines without major modifications. Any drawbacks? Do you blend before filling your tank? Mixing? Heating?

Thanks for the expert suggestions

blending works for some...

its not a panticea (spelling)

that's why so many spend so much on conversions...

would run but not over 55????

did he bother to try replacing the filter?

As the filter plugs, the car will still run fine, but your top speed will slowly deteriorate as the filter can deliver less & less fuel at full throttle. You don't even notice it until the "surplus" filter capacity falls to zero and then below zero the engine's fuel demand at speed.

You can't say 80%WVO 20% RUG will work in a diesel engine. It works in my Benz (VERY fuel tolerant) here in central FL (nice and warm most of the time) the way I drive (hard and longer trips frequently). Any of the variables can change and that may mean your engine will NOT work well on a blend.

I mix well before I put it in the tank, I added a FPHE and injector line heaters to help warm up the blend. If you use RUG, you can't get the blend much over 130-140F before you may start bioling the RUG which will give you bubbles in your fuel and make it run badly or stop altogether.
