When should a tune-up be done on a 2011 maxima on 2011 Nissan Maxima

Some say after 7500 miles and some say about 2 years because it has platinum plugs

I will assume you meant 75000 miles and that is a reasonable timeframe for spark plus depending on how you drive. 7500miles is probably the recommended oil change period. Every 2 years would be more on the lines of air fiters and such. Depends on how many miles you put on in the timeframe.
