Recently was looking over the service history of my 2015 mazda 3 and noticed something terrible. I went from 6/22 - 11/23 without an oil change. I hardly have been driving this car so I didn’t even realize it had been so long. My sticker only had a mileage on it and not a date and I stupidly didnt realize how long it took me to do 5k miles. The car only has 85k on it.
I live in Chicago which is a harsh climate with mostly city driving. However, the car was opened up on the highway every month or two for a decent amount of time/distance. How much damage might have I caused? It had full synthetic in it at least but I am terrified because this car is expected to see a lot of use from here on out and needs to last which I’m afraid is not going to happen now.
Oil sits on the shelf at stores for years, the time intervals are a scam. I’ve always changed my oil off of mileage, all my cars engines have lasted over 200k.
