I stopped changing oil at 3,000 miles after a mechanic in Denver called me out
I used to be that guy who changed his oil every 3,000 miles like clockwork. My dad taught me that, and I figured it was cheap insurance. Then a mechanic in Denver looked at my service log and asked if I just liked burning money. That stung but he had a point. He pulled the manual for my 2016 Civic and showed me Honda says 7,500 miles or whenever the oil life light comes on. I switched to following the light and using full synthetic, and I have not had a single issue in 60,000 miles. But now I wonder if he was just tired of doing unnecessary work or if he was actually right. Some folks say the light is set for ideal conditions and city driving is harder on oil. So where do you all land on this? Do you trust the owner's manual and the oil life monitor, or do you still go shorter because it feels safer? Real answers only, I want to know what people actually do not what the manual says.
My uncle was the same way about his truck, swore by 3,000 miles no matter what, and then his 2012 Silverado hit 280,000 miles on whatever oil was cheapest at Walmart. He never once used synthetic and the thing still ran when he sold it. That always made me wonder if half this oil debate is just habit passed down from when oil was way worse than it is now.
