I purchased the car CPO about 4 weeks ago. I had the car for about 2 weeks and the other 2 weeks it's been at the dealership, where they are working on replacing the injectors, cylinder head, and intake valves.
I had only filled up the tank once so far, but in CT, all I can find is diesel with cetane rating of 40. So the previous owner probably also filled up with the same cetane rating since the car was originally purchased in CT and serviced in CT.
Do you know which gas stations have better diesel?
