Maybe this is all in my head...I just had my oil changed and went from Mobil 1 to Pennz Plat (both 5W30) and I swear that the engine doesn't seem as smooth as it was with the M1...is this possible? It has onlt been maybe 250 miles since the change...does the engine need to adapt to the different additives etc?
