hey guys i recently hit 4500 miles and did my oil change a little over the 3k mark. however lately its been getting in the 20-30 degree f. i notice when i go and start my st up that the oil pressure is normal at 35psi however once i get on the gas it shoots up very high nearing the 70psi mark. should i be nervous? i let the car warm up for 3-4 minutes before i hit the road. i guess i never really looked at the oil pressure gauge but don't want to cause any damage so i figured id ask where people actually know these cars. Thanks!
