Hi,
What is RUG ???? or what does it stand for ??? I am a beginner in WVO conversion process. Since diesel prices are close to $4 here in Texas , i am thinking of using a blend mentioned by spark3542. There is a site called dieselsecret.com where they sell you additives to make a proper blend. IS it worth it ??? i have 90 300d. Thanks
