How long does the residual oil in the engine protect the internal surfaces and bearings on startup? I ask because I was cleaning my car out and when I installed the floor mats I must have gotten them wedged between the brake and gas pedal. When I pressed the brake to start the truck it must have pushed down the gas pedal because as soon as the car started it went straight to redline which is about 6000 rpm on my Tacoma. I had driven the truck about 2 miles to the car wash and it was turned off for about 20 minutes. I’m a little worried that I may have damaged something since I doubt oil pressure would have built up prior to it hitting redline. It’s not knocking and I don’t see any smoke but I’m worried that I may have compromised the bearings and will end up with issues down the road.
One thought I had is that since the oil pump works off the crank, it shouldn’t really matter if the truck idled at 800 rpm for 7 seconds or if it rev’d up to 6000 rpm over the course of a second. The amount of rotations the pump would have made would have been the same so about the same amount of oil should have flowed through the engine. I’m not sure if this logic is true, I’m just trying to rationalize whether or not I could have done any damage to the engine.
What do you all think?
