A friend of mine that has a lot of construction equipment was telling me about how well Lucas Oil does in his equipment. Does anyone have experience with the stuff? I know it is more expensive than synthetic oil, I think about $7.00 a quart. He has an excavator with 16,000 hrs. on it (equal to around 800,000 miles on the road) and says it uses no oil and runs great. I want to stop my 1992 GMC pickup daily driver from using oil, it has 200,000 miles on the engine, he thinks it will stop the oil burning in just a few hours running time. Anyone know?
