I've had an 06 dts for about 6 monthe and
have changed the oil twice with
conventional oil. Im a 1,000 miles past the
due date.I'm getting it changed tomorrow.
Question is, have I already done damage??
Also, does this vehicle require synthetic??

1 Answer


Do you do a lot of around town driving or highway? Ever which one it is, I change oil at 5,000 for around town and 7,500 for truly on the road driving. I mean all real highway. A car your age should not require synthetic oil but they say you can go longer on a change, as much as 10,000 miles depending on the vehicle. I would not go that long but that's me. You went 1,000 on a real oil change. Probably will not hurt too much the first time, but if you make it a habit will cause issues down the road.

    I was looking at your Cadillac DTS cars but had a question about them. My understanding is that Cadillac started making the DTS in 2005. How is it possible to have a 2003 DTS?
