[QUOTE="Black Thunder 715, post: 14712907, member: 149136"] Beast,question: I've been using 10w30 in my '13 shelby gt500 ever since I bought it new and the engine has run good ever since. I changed the oil from mc 5w50 to mobil 1 10w30 the very same day I bought it and the car has the stock thermostat. I'm in Tampa bay where it doesn't get too cold. The question is how come certain cars like the corvette zr1 and the '15 z06 call for 5w30 factory recommendation and not 5w50 even though they are also supercharged just like the shelby? My car also gives good mileage with the 10w30. I only used mobil 1 one time and have been using Penn ultra after the second oil change. Do you think there is going to be any long term damage if I continue to use 10w30? I don't track or race the engine except for an occasional moron that wants to do a 5 second run from the red light.
