Not sure if this is just in my head but since switching to GC 0w-30 coupld days ago over Mobil1 10w-30 which I ran previously the car seems to be more sluggish in its operation. I know GC has more hot viscosity, is there anything else between the oils that could result in this feeling. My engine has balance shafts down around the oil pan, and there isnt any windage tray either on this engine. I just think the engine was a bit more eager to rev when it was running Mobil1 10w-30, perhaps it has less friction compared to GC. Any opinions or thoughts on this. Lastly I could just be dreaming all this up as well, dunno.
