Nissan says to change your oil and filter at 3750miles, 7500miles, 11250miles, 15000miles, 18750miles, 22500miles, 26250miles, 30000miles, 33750miles, 37500miles, 41250miles, 45000miles, 48750miles, 52500miles, 56250miles, 60000miles etc.
How many of you are running oil coolers?
I find what you say to be really interesting, and the advice you got, do you know any of the reasoning behind that advice from the Nissan/Infinity techs?
Personally I'm OCD about changing my oil 3,000 miles or before, and usually check it everytime I need gas, and never once have I found any less oil on the dip stick. I use nothing but Royal Purple, and synthetic Valvoline oil in all my cars, and so far only Royal Purple in my DD 09 Nismo, but thinking about trying Redline out. I never have had one oil burning issue even racing in super hot weather. I'm also running a 34 row oil cooler.
The only thing weird I've learned about the oil I use is never put royal purple in a subaru, cause it jells up in the heads.
I my opinion Mobil1 is **** oil cross the board. I know some guy swear by it. I ran it twice to try it out. Once in my 240SX, and once in my Titan, and changed the oil out on both even before I hit 1,500 miles. I got worse gas mileage on both, and my VK56DE made valve train noise at higher rpms.
