Scotty whats your thoughts on using part of your old oil and kerosene to flush your engine of sludge in the engine before an oil change? Will this damage any of the seals or gaskets or engine components? Thanks

just change the oil a lot, flush only once with a good comercial product if you got a muddy engine (if it's caked up then it's far more complicated, requiring engine disassembly)
