DIY Engine Oil Change of the Infiniti Q50

Warning: If you are not mechanically inclined or do not have the appropriate tools and/or appropriate safety equipment, please do not attempt this. I will not be held responsible if your Q50 damages you.

Why do I prefer doing my own oil changes? Well with longer maintenance cycles and less stuff breaking down, gives me something to do on the car, and an excuse to spend time in the garage. Plus, I know it is done right - seen too many cars driving on the road with panels hanging down and heard too many stories of stripped drain plugs, too much oil, wrong type of oil, too little oil etc. While, I trust my Nissan and Infiniti dealerships, I don't trust quick change places. Lastly, I know what is oil is going in and I can usually do it a a fraction of the cost of any other place's cost of using fully synthetic oil. It is really a $30 cost of prevention.

Draining the Oil

Step 1: Buy Necessary Items:
You will need:

• 5 and 1/8qt of 5W30 engine oil are needed for an oil change with filter change. I prefer Mobil 1 Full Synthetic 5W30 Engine Oil. I pick it up at Walmart for $24.40 for a 5qt jug. It is enough for an oil change without needing the 1/8qt as not all the oil 
• 1x Nissan Engine Oil Filter Part # 15208-65F0E, that ranges anywhere from $6 to $8 from your dealership. I prefer using the OEM Nissan one to ensure warranty, and also because it contains the relief valve inside. There are better aftermarket filters, I have used Nissan ones for 15 years without an issue. Do not use 15208-65F0C, that is an old part number that has been discounted and has a cardboard end-cap and it's made in China.
• 1x drain plug crush washer part # 11026-01M02

Understanding & Adjusting Headlights and Fog Lights on the Q50 for Maximum Visibility

Understanding the Q50's Exterior Lighting System

The Q50 has an advanced mechanism for the headlights, especially given the "auto" mode features and the steering adaptive headlights, and the auto leveling system. These are collectively called the "Adaptive Front Lighting System". Unless you test drove and bought your Q50 in the dark, chances are the dealer has been unable to show you this functionality. The working of the headlights is explored below.

The day time running LEDs (powered by 7.5W LEDs on each side) that circle the low beam projector are always on when the car is started. This is with the setting on the headlight stick being OFF.  They project enough light for the Q50 to be seen even on bright sunny days. As for the amount of useful lighting they provide, see the video, but it is not significant for any situation. The DRL LEDs do stay ON in all modes of the headlights.

By selecting the next setting on the stick which is AUTO, the systems many features are enabled. In auto mode, the LED low beams in projectors (powered by 23W LEDS each) come on, but only when the ambient light sensors detect that it is dark enough outside. The sensitivity can be set through the InTouch menu. They also go off after a number of seconds when the car is shut off or locked, again the timeout for this can be set through the InTouch menu.
