Congratulations and we all share in your enjoyment.
The XLR is truly an outstanding machine as evidenced by the majority of satisfied owners who contribute to this site.
Equally important, in my mind, is this forum allows us communicate directly with each other; share experiences and identify any problems related our unique vehicle.
When you reach 500 miles, I would suggest an oil change.
The dealer will tell you that it isn't necessary that early. That's what GM tells them and, of course, the synthetic Mobil oil is expensive.
Insist on it!. I don't care how clean their engine assembly plant is.
Facts are; new engines shed metal parts into the crankcase. Flush those out early with an oil change. It's the most important oil change you can do for the life of your engine.
I have built many racing engines and every car I've owned has had this 500 mile oil change philosophy. My 1974 Datsun 260 Z has over 200,000 miles and still runs like a top.
I trust that the Cadillac Division at GM is monitoring this site.
As a manufacturer, it seems to me that this site is an incredible source for them to validate their market share and make adjustments( almost in real time) to consumer preferences.
The XLR is a breath of fresh air in U.S. automotive innovation.
My hope is that GM will visit and recognize the advantages of this website and capitlaize on the inputs from all of the Forum contributors.
