What maintenance schedule are you following (US vs Canada)

[fooitm35x]

I am wondering if my fellow Infiniti owners can help me here - I was always using the PDF for my 07 M35x maintenance I downloaded from either one of the links here on the forum or from Infiniti USA, it has very clear schedule when and what needs to be replaced, so it has been easy to follow.
Recently I checked Infiniti Canada online maintenance schedule and it is (unless I cannot read) very different.
It does NOT call to replace automatic transmission fluid, differential oil, etc, what it does tell me is to replace spark plugs at 168k km (104k miles).
The PDF I mentioned above doesn't tell me to replace spark plugs at all.

What schedule are you following?

PS: My car is 2007 M35x with 177k km or 110k miles and I am due for 99 months service but I didn't do anything on 96 months service, so now it's time to catch up as I plan to keep this car for a bit longer.

I reckon that the owner's manual in Canada would be slightly different than in the states due to different climate conditions and the differences in fuel formulas (due to diff regs in Canada Vs US). If you live and drive in Canada, it's best you follow Canada's schedule for maintenance. As for spark plugs .. my owner's manual for my 07 M35 also did NOT list anything about changing plus. Assuming that Infinitis sold to Canadian dealers have the same plugs as those sold to US dealers, I would change them at 100k miles. My dealer told me they recommend changing when they stop performing at spec - regardless of mileage- but that is usually at or slightly over 100k miles.
