As a general question whenever you have switched from Dino oil to synthetic do you HAVE to stick with syn forever? Diesel or gasser, Does it hurt or affect anything if you changed back to dino for a few changes say and then went back to syn? I know it sounds crazy but I got a chance to get a fair amount of new dino oil free and I have been running syn in some of my vehicles....:drinkup: Thanks !!

If the engine's are in good mechanical working order go for it, Free oil is priceless :clapping::clapping::clapping::clapping:
