MPG from Q50 on a Long Road Trip - Computer and Manual

Drove down from Madison, WI to Chesterfield, MO to watch the eclipse with the kids. Thought I would record the MPGs that the Q50 achieved during the mostly drive.

The summary is as follows per the car computer:

Changing Key Fob Battery

After almost 3 ½ years of usage, I got the following message. Neat.

Awesome that the car detects Key Fob battery level

Changing Wiper Blades Inserts in Q50 and Retaining the Wipers.

Having a streaky wiper is huge pet peeve of mine. The windshield is meant to be used to look outside not be distracted but some dirt line on the screen.

I like the outside shape of the stock OEM wipers blades, very aerodynamic. I also like the silicone material that comes with the OEM Infiniti and Nissan cars. I have tried many aftermarket wipers one ranging from $10 to $25 per blade and all I have found is that they have a short life and right after the first winter they harden and start streaks…so irritating. So either go cheap so you can throw them away every 6 months or go OEM, but Infiniti charges quite a bit and also use the “value line” instead of OEM Japanese ones.

Getting Rid of Run Flats & Adding a Spare Tire to The Hybrid Q50s

It has been a very big point of contention within the Q50 community about Infiniti’s choice to opt for run flat tires on the Q50. Not only do run flats ride harsher, cost more but they have a low thread wear rating of 280AA which translates to 18,000 miles only. Lastly run flats are great if you “plan" on having protection against getting a nail/screw etc, but if it ends up being a side wall damage or damage due to a big pothole or other object then the run-flat tire is pretty much useless. Call me old school, but one one the first things my dad taught me was to change a spare on a car before I could even drive the car - secure car with chucks, loosen lug nuts, jack up, remove flat, replace with spare, soft tighten lugs, lower jack, fully tighten lug nuts, off you go.

DIY Changing Front & Rear Differential Fluids

The AWD Q50 has 4 additional mechanical fluids other than the engine oil that need attention. The rear differential (same as only RWD Q50) as well as Front differential oil, transfer case and transmission fluid. 

Historically, I have found that the differential fluids have usually got a specific mileage at which they must be changes, however for the Q50, the only recommended maintenance is to Inspect the fluid every 10,000 miles or 12 months, unless towing a trailer, or driving in rough conditions in which case it is recommended to change every 24 months of 20,000 miles.
