The Nissan engineers say so you need to re-read that again. Quit trying to be an authority on oil change schedules when you're not qualified to offer such advice. and you are???

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 it doesn't state that. I change my oil, Mobil 5W-30, once a year but I also store my car for the winter.please post your vin so no one buys that car My engine will last as long as anyone who changes their oil at 3750, 3700, 3000, 2500, 2000..........well you get my drift.proof? 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.yea toyota camry's and only 100k miles thats because you don't follow that manufactures maint. schedule! But if you want peace of mind and have money to burn, go for it.

I also love how you tell him oil analysis is worthless I've never had one done in 41 years of car ownership. Millions more like me. Oil analysis has it's place - in industry, not so much for common folk, your post and advice falls in that category.

Hard earned money??? its 50 bucks you cant even take someone out to eat for that! Glad you have money to burn. I'd rather be sensible with mine and save it for mods, wife's birthday, etc.

Now, go read the conditions in schedule 1. Alot of Z owners do not fall under schedule 1 but there is so much internet hype on oil that people are changing their oil at 3750 miles when there is no need.
