How Good Is Redline?

Yes, read the OM. People like you spread BS on when to change the oil. You only need to change the oil at 7500 mile intervals unless you drive under certain conditions as stated in the OM. And guess what? The Nissan engineers say so. Quit trying to be an authority on oil change schedules when you're not qualified to offer such advice.

joshs09slvrZ,
Read your OM and decide under what conditions you drive your vehicle. You can go up to 7500 mile intervals as stated in the OM. I change my oil, Mobil 5W-30, once a year but I also store my car for the winter. My engine will last as long as anyone who changes their oil at 3750, 3700, 3000, 2500, 2000..........well you get my drift. If you track your car then you may want to consider changing your oil sooner. And don't waste your hard earned money getting an oil analysis. Millions upon millions of ordinary people drive gazillions of miles and never have an analysis done and their engines last over 100,000 miles. But if you want peace of mind and have money to burn, go for it.
