Call me a dinosaur, but I still believe in doing the first oil change right after 1000mi. So I made an appointment and went to the dealer today to get my oil changed, since I now have 1050mi. Don't get me wrong, I appriciate an honest service department. The service writer asked me if I really wanted an oil change so soon. She went on to say how new engines are already broke in from the factory and I'm wasting my money. I just smiled and asked her to humor an old man, I'll get it done anyway. So I'm thinking, if engines now a days are broke in direct from the factory, then why does Chevy have a rather strict break in procedure in the owners manual to follow. I also asked her what her opinion was to when would be the best time to change to synthetic. I was thinking about doing that at about 10,000 mi. She said that she didn't recommend ever changing over to synthetic if the engine didn't require it....again, I'd be wasting my money. Just curious what opinions you might have on this.
