First oil change 2008 Yukon XL

[Yukon Joe XL]

I know the theory used to be get an oil change after the first 1000 miles.(metal shavings etc,,) My mechanic friend believes that no longer applies to the newer vehicles and have heard others say the same thing.
I' m at 1200 miles now and will probably wait till about 3000 miles. I will be keeping this vehicle for a long time and wonder what advantages would synthetic oil have. I put it in my Corvette but that has almost 100,000 miles on it and felt this would help it stay cleaner,longer.....it also sits in the garage for long periods of time in the winter. A new car with synthetic? Does it make a difference other than fewer oil changes? in the long run?
Thanks, Joe

A lot of us on here use synthetic including myself. I think it is also wise to change out the oil between 500 and 1000mi. Oil is cheap, engines aren't.

I did my first oil change with Mobil 1 and go by the DIC which a GM mechanic said was ok. The synthetic oil should be good for 5-6K between changes. Of course, it depends on your driving style, highway versus city driving but have not had any problems after 18 months and 15K miles. Just my 2 cents...

I changed out the factory oil at 3000 mi. and put in Royal Purple synthetic and a K&N Gold filter and it hasn't blown up yet. Must be OK!

Thanks for the input. I ended up changing the oil at 1350 mi with Mobil 1 sythetic. Now back to the mods

Any problems changing to synthetic at 20k? I have standard oil from the get go, should I make the transfer to sythetic? I have used synthetic in my Trans AM and Harley all of their lives I guess I should be treating my Tahoe the same.

20k shouldn't be a problem. You really only should have a problem switching when your car gets up there in miles.

I go by the DIC also, and have done so since day one. I get about 9000 miles between oil changes.

I change once a year, but I am not using vehicle everyday. I only drive about 7,500 miles a year. But I feel that once a year is all I need with the Mobil 1 synthetic. It is a ritual to do all the vehicles, over the Thanksgiving weekend. I also recomemend a synthetic filter like Mobil 1, K&N, or the Amsoil EA.
