Aged of the engine, when was it last had head work, what did they do, what do you use it for. These are questions that you need to answer. I retired from a pipeline company 3 years ago that we loaded and pump gasoline and diesel fuel. Lead in the gasoline help lube and clean the valve train. What they found out first thing out of the box with no-lead gasoline was that deposits would build up on the valves and seats and cause burning. Older engines this would a serious threat with the softer valves and seats. They did two things to try and cure this. One was to put harder valves and seats in new engines that would not be damage as bad and the other was to add valve cleaner in the gasoline loaded for retail and we went over 10% additives for 10% blends to stop the deposits. Myself I have a Farmall 400 and use a lead substitute additive because I use it for snow blowing, moco, plowing, disking and baling. Now this additive has no lead in but is suppose to do the same thing as lead, clean and top lube. I have been doing this for over 20 years. The additive is a cheap investment instead say a new valve job on the engine.
