The doom and gloom of the switch to unleaded fuel eating valves in cars never happened on the large scale we were told was going to happen. Yes I am old enough that I never saw the problem of vehicles eating valves and developing upper cylinder wear when lead was removed from auto fuel. Yes I was driving cars when all auto gas had lead in it and was driving the same car when the switch to unleaded gas occured. I had four uncles in the auto repair and gas station businesses. My uncles did not get more work when the switch to unleaded fuel occurred.
Others talk about the wonders of Marvel Mystery Oil (MMO) being added to their fuel. IMHO, those that are worried about lead being removed from our AvGas can find a solution for the problem by adding MMO to their unleaded AvGas.
Please pass the pop corn as this thread is going to get interesting.
Using Duck Duck Go to search the internet, (people can say anything on the internet and do) one will find both articles saying removing lead from fuel will cause wear and articles saying removing lead has more benefits than short comings. I just want to see the RAW data and draw my own conclusion.
