best suited trucks for WVO use?

Postby beeline » Fri Jul 10, 2009 8:08 am

hello forum members,
not sure if this post belongs in this column, but here we go...

I am looking at getting a diesel truck to run on WVO with a two tank system. Reading in this forum and other places, it seems the Dodge 12 valve engines up to may 98 (?) are the best suited? do you agree? when they switched to the 24 valve engine, did the injector pump change as well? Up to what year did they have a mechanical injector pump? and what other changes (favorable/unfavorable) were introduced with the 24 valve engine.

So far I am not considering any GMC's and don't know too much about Ford's, but any insight as far as which years and models of engines/injection pumps work best would be great.

I am not set on a particular truck, just looking for the best suited setup to run WVO regarding amount of changes and reliability. Thank you for your insight and time.

If you're in Canada you can get Toyota trucks with inline mechanical IPs that are ideal for VO fuel. In the US the Cummins 12v with the inline mechanical IP is your best option.

Dodge Cummins from 94-98.5 are the best since they have the strong inline Bosch IP.

The 24 valve engine is a far different and weaker IP, and much more expensive to replace electronic injectors.

The old <94 Fords I have seen all used a stanadyne rotary IP, the weakest you can get. Starting in 94 Fords use the powerstroke engine which is a good design but harder to convert and needs more expensive repairs than a Dodge.

The deadheaded fuel system on the 99-03 powerstrokes make it ideal for a veggie conversion. I would posit that the Ford is easier to work on yourself than a dodge or chevy.
Also, the powerstrokes do not have an injection pump, which is a very expensive fix on the dodge.

12 valve cummins hand down. minor pump mods, injectors and exhaust will make 650 ft lbs easy and accelerate your 5th wheel uphill in OD. motor super easy to work on compared to the others. people pull the entire cab to do headgaskets on the V8 diesels. glowplugs on the powerstroke are no fun either.
