Just a view from South Africa - here biodiesel is priced as just below regular diesel so its not worth it ( energy density is some 10 % less ) + its quality is dubious. WVO is arround a third of the price of diesel here it become pure economics ( if you don't count all the hassels with WVO) ) to r

Just like with WVO, most home-brew biodiesel systems don't work properly, and aren't really producing ASTM D6751 Biodiesel. The only way to know is with a lab test, and we really need a cheap non-profit testing service so that home-brewers can have a quantitative way to determine the qualit

I have seen plenty of research showing WVO systems operating for long periods, without serious engine wear, and other studies showing major engine wear in short periods of time. I really don't think there's anything inherently wrong with WVO, other than it being extremely difficult to build

Peter, Intermittent missing can be a sign of weak compression on a particular cylinder. Cover your bases and do a compression test or, better yet, a leak down test if you have the equipment. Prior to checking compression, make sure valve lash has been set properly for all valves. While checki

A friend of mine brought his W123 300D ( Non turbo ) to me to try and sort out his intermittent idle problem. - Usually the engine purrs nicely but then every now and then the idle speed drops and engine runs roughly. When this occurs I isolated the problem to #1 cyl - ( by disconnecting each fuel
