I have a bad engine bearing that was causing my oil light to flicker. Mechanic said bad engine bearing is causing low oil pressure and that I needed thicker oil, so he added Lucas oil thickener. Problem is, I'm at the store and I am not sure what thickener to use. Lucas Heavy Duty or Lucas Synthetic. Please send me your thoughts on the situation and what to use.
