My mechanic cousin called me out on obsessing over synthetic oil changes

I always changed my oil every 3,000 miles with the expensive stuff, you know, the full synthetic. My cousin Mike, who runs a shop in Akron, saw my receipt and said I was wasting about $40 per change. He told me modern engines can easily go 7,500 to 10,000 miles on synthetic, and that the real killer is letting the oil get low between changes. That hit home because I realized I'd spent an extra $160 over the last year just following old rules. Has anyone else gotten called out on a car maintenance habit that turned out to be overkill?

Wait, you spent $160 extra just because of an oil change myth?

My cousin fell for that same thing at Jiffy Lube last year. They told him his car needed synthetic blend at $90 a pop when the manual literally says conventional is fine for his 2012 Civic. He paid that extra for like four oil changes before I told him to check the owners manual. The worst part is they upsold him on a $70 "engine flush" too which is basically just pouring in some additive they buy in bulk for pennies. Honestly the whole quick lube business model is built on making people feel scared about their engines.
