Well I am on my second half tank of SVO, with no mods to the truck. Period. No heat lines, or extra filters. Am I being brave, probably. I started with about a 50/50 mix, and have been adding SVO 1/2 tank at a time, leaving room to dilute with diesel if things get harry. So far all is good. I have driven close about 300 miles on SVO in town. I am in the NW and it has been in the upper 80's during the day and own to the 50's at night. I noticed that it does start kind of hard in the morning at 55 degrees out, with no heat. However if I plug in the factory block heater, no noticible startup differance at all. [img]/ubbthreads/images/graemlins/grin.gif[/img] I have noticed that bottom end power is about the same, maybe even a little better throttle response, however it does not like to rev past 2500. I am thinking that has to do with the fact that I am not heating the oil at all, only what the factory filter and motor heat the oil. I called a local diesel performance shop today to ask what experiance if any they have, and if he is interested at all, and got the blow off. No interest at all, says it will have a lot less power, although he has never dyno'd one, and doesn't care. think maybe I will avoid that one.
I only know of one "diesel performance" shop in the seattle area. This one wouldnt happen to specialize in BANKS products and be based out of Enumscratch would it? If it is, that wouldnt be the first time I've heard of people getting the blow off from them.
I would be very careful running 100% WVO without ANY additional heat other than the engine block and fuel bowl heater. Cool/Cold WVO *WILL* screw up injectors on a DI engine. That much has been documented on other sites already.
Cutting it with #2 seems to help with the cold weather starting, but running 100% WVO without mods is asking for trouble. Especially when the weather turns. Lets see, seattle area summers last about ohhhh, 4 weeks, so better start getting those heating units installed [img]/ubbthreads/images/graemlins/wink.gif[/img]
Heating it changes the combustion properties, to allow for a more complete combustion.
At least that's what I've read so far...and it makes sense. The job of the injectors is to "atomize" the fuel while delivering it in a specific spray pattern. The two things that a good injector shop will check is the pop pressure and the spray pattern.
Given that SVO has a much thicker consistency than #2 fuel, I would expect the atomization and spray pattern to be impacted. By heating it up you're lowering stress on the injector pump, and delivering something that's much closer to #2 than cold veggie oil would be.

Okay so the reason you can't rev good past 2500 is the WVO is too thick if it is not heated. Your fuel system and oil system can't reach the right pressures to move, inject and atomize the WVO properly. I think you are running on borrowed time if you don't get a heater on your truck for the oil!
The VO does not harm the injectors per say. But if it is not heated and burning cleanly then it will choke up the injector nozzles. Also it could choke up the pistons and rings. But I suppose if the injectors are run long enough on a VO that is not the correct viscosity then they might become damaged over time from added stress.
It is cool you gave this a try but I don't think it is a good thing to do for long term. If you are not going to add a heater to the WVO then go back to a 50/50 blend. I would hate for you to much up your injectors, oil system, fuel system or engine.

Yep, I pretty much agree that the reason for not revving is the added viscosity of the oil, and I will be mixing with Diesel untill I add a heating system. I am still working on a few different ideas on paper as for how I want to finally set my truck up. It is nice to know none the less that the truck will run adequately on SVO with no mods what so ever.
i'm running cold pressed rape oil (hope my translation is right [img]/ubbthreads/images/graemlins/crazy.gif[/img] ) and it runs perfect. no rev probs, no start probs. don`t know if you guys get it over there? i guess most of your oil is made of beans? maybe its a difference between the oils?

Figured out my rev problem. On my way to work this morning It got to the point that I couldn't go above 60. Come to find out, the fuel filter was plugged up with the "wax" from the oil. I was able to blow it out well enough to get on the road again, but will have to figure out a fix for that, like heat. I know that with it heated the oil does not coagulate around the filter like that, since that Is what I do when I filter it before going in my tank. So far that is the only problem I have had. It does start hard when cold (55*)but has never left me wondering if it will start. I have heard that those who switch back to diesel before shut down also have hard start issues.
you have to switch back to diesel early enought, the pump has to push all the svo out of the fuel bowl AND the fuel rail and that takes some time. i had about 50* this morning and it took about 2-3 sec of cranking to get it startet. no other problems right now, except the the strong mcdonalds smell [img]/ubbthreads/images/graemlins/smile.gif[/img]

Rapeseed oil is commonly called Canola oil in North America and the USA and it is readily available. But soybean, peanut and corn oil is more commonly used for cooking and that's probably mostly what you get in waste oil around here.
