No don't worry about it, we're always anoying the ****e out of one another on this forum
with regards to using VEG as fuel, there are many ways of doing it depending on the type of oil you want to use. I started mixing SVO and diesel this year as a way of reducing the cost of diesel and have had no issues, but thats not the same as home produced or shop bought biodiesel or the same as WVO. I think the problem is many people get them mixed up or believe they are the same thing.
So maybe we need some clarity.
WVO - waste veg oil, or chip shop oil if you like, needs to be cleaned and filtered and can be processed into Biodiesel if you want or just used straight if you want. If used straight expect to need new fuel filters more often or use another fuel filter in the line first to catch the cod n chips.
SVO - straight veg oil, or cooking oil bought from Tescos if you like. Doesn't need to be cleaned or filtered can be burn't straight or processed into biodiesel if you want but would make your bio expensive. Its heavyer that derv so can damage weak fuel pumps.
Biodiesel - Processed veg oil that has been treated to make it as close to diesel as possible therfore reducing the damaging effects of using Veg Oil in an engine and pump designed for DERV, Biodiesel can be bought from suppliers but can also be home produced and very nearly free if you can get the WVO
Why can Veg damage an engine.
Diesel Pumps on modern engines are designed for a fuel that is thin and viscous, Veg Oil when cold goes thick, likewise so does DERV which is why DERV comes in a winter flavour as well as a summer flavour. In cold countrys they use a very special derv that stays viscous down to very low temps. Veg oil does not contain these adatives so will 'wax' up even in a mild winter. Hense those buring SVO or WVO like to heat it up before trying to use it. You can get away without doing this but you will wear out your fuel pump quicker. The other known issue it that the seals in pumps and the fuel lines can be damaged by Veg Oil.
My personal advice is don't discount Veg Oil as a way of running your engine, find out as much as you can first tho, which is not easy as people who do it tend to be fanatical and ignore some real issues also those that won't are also fanatical spouting hearsay and anti veg propaganda as fact.
This is not complete and there is lots more to add and debate but I like these threads and think its good to get as many facts out as possible, I know others on the forum use various forms of Veg Oil,
n8rbos is one, read it all its all good advise from people who are doing it for real.
