Since Ive been hearing a lot about polymerization, I was wondering about the normal WVO/SVO operation that most people do with the heating of the oil in the tank and filters before the oil hits the injection system. If polymerization happens to oil when it gets hot, I was wondering if thats pretty much inevitable even with standard SVO systems, since the oil is getting heated to approx 200 degrees, then when it hits the injection system and gets pressurized (which raises temps itself). Along with the recycling of unused fuel oil in most normal FI systems, youre getting this hot oil being returned to the tank to be used again, so again, Ive been figuring that this polymerization event was pretty much a given even on regular SVO systems. Then theres also the idea that ALL WVO that us greasers collect has already undergone superheating (up to 350 degrees), so I would figure polymerization would definately be a given on WVO. The way I looked at it, any thick oil that was formed through any heating, either before or after hitting the fuel tank, would be caught by the filters in the vehicles fuel system before it hits any sensitive areas. This also applies to the glycerin that is present in the oil too. Any extra information to help me form a better conclusion on the whole WVO/SVO controversy would be helpful.
