I am not a genius, chemical engineer, mechanical engineer, or anything worth mentioning. What I am is someone who has been in the industry a long time. Almost 30 years. What I am seeing is oils that are meant to protect your engine, transmission, transfer cases, and differential are getting thinner and thinner. In my opinion this is to improve fuel economy due to some regulations, but what it is really doing, especially in harsh metropolitan areas, is cause extreme excessive wear. Premature failure. Expensive repairs on vehicles that cost more then a decent place to live should.We are forced to pay premiums for everything, and expected to just eat it when it doesn't last. That is just a rant for today
