I brought my 2012 Tacoma 2.7L 4-cyl to my local dealer for the first maintenance free oil change and tire rotation at 4800 miles on the odometer.
I just today checked my oil level and was SHOCKED to see the oil measuring an INCH AND A HALF ABOVE the full dot. I called the dealership and the maintenance manager explained that the machines at the dealership auto-fill the trucks to a specific amount and maybe one of the machines is not calibrated correctly. He said that more oil would create air bubbles, throwing an engine code.
My odometer now reads 6800 miles so I have driven 2000 miles with the oil being over serviced. I would change the oil myself if it wasn't free. I drove the truck and got the engine warm and checked the oil with no change noted.
1)Will this hurt the engine at all?
2)Has anyone else had this issue before?
I am headed to the dealership tomorrow morning at 8AM and will post later. What do you guys think?
