Absolutely. Still nervous about 100% WVO. The biggest issue with WVO is potential for ring coking, water contamination, etc. Also you don't know the quality and origins of the oil. I'm buying the cheapest oil I can buy, from Tesco, but I know it's 100% Rapeseed, or Sunflower. There's a chance the WVO you buy is GM Soya oil, which is a drying oil agent and can cause your piston rings to gum up and go sticky. It's also very hard to filter absolutely everything from it. I think if I was able to produce it myself, I'd try it, but buying it I'm not so sure still
