Re: How To: Reduction Gear Oil Change

Fri Jan 12, 2018 1:50 pm

Is there a recommended maintenance event for this? My 2011 gen1 is almost 8 years old/65k miles. I never had an oil leak ever, and I am always at 4.0miles/kwh for the last 8 years.

Do I need to change this oil?

this is obviously not very scientific but there are some single digit efficiency gains possibly to be had by swapping to the redline D6 fluid over stock fluid.

if you look at my pictures the oil was not terribly dirty at 44k. it is a preventative maintenance thing that won't hurt you, could help you, and gives you peace of mind that the reduction gear is wearing normally. Technically, Nissan does not require you to change this oil ever, only inspect.
