Again, i recommend the amsoil because yes i sell it, but you are free to use any fuel system cleaner. If not the amsoil get redline, im merely making the point that fouled injectors as well as carbon desposits can be an underlying source to noises and other issues. (Common also with emissions). You have to remember i grew up around cars and am an automotive engineering major and have worked in a lab testing synthetics and their effects. Many people fail to understand the importance of proper lubrication as well as fuel system cleaning. Especially if you have lower octane fuel with higher ethanol amounts and lack of a high quality additive package. If you dont like professional advice dont take it and move on. Irs your vehicle.
