Be careful with the oil selection with deviating from spec and other mods like grill blocking without doing the homework, readings and testing. Never Ecomod to the point at which your cars reliability and proper engine functionality may be compromised in any way or your go against your warranty (unless you just don't care about that). If your engine starts to perform poorly or dies, you have completely lost any advantage you were seeking in saving 10's and 100's of dollars to loosing thousands very quickly.
