So I took my 2010 SS to the dealership to change my oil (first mistake
) on the way out of town, and when I paid I realized they had used regular instead of synthetic, the main hint being it was 40$ cheaper..
They said it wouldn't hurt having regular in it for one oil change but offered to drain it and replace it with synthetic if I'd like. I was in a hurry so I didn't, but I'm wondering if I should first thing Monday?
Or will it really be okay having regular in it for one oil change, and if so is there anything I should avoid? Such as going over 150 on the interstate...
