Coyote oil change: Why change oil before real miles?

Ok, you are thinking, “hey, you have not driven this thing yet, why change the oil”?

Lean bank #2 and AED Tuning

Long story short, we have worked on Coyote fire-up since April. That is about six months too long. We get spark, air, and fuel. However, bank #2 on the driver side stays lean. Everyone has inputs, and we tried them all. Therefore I am done guessing. Tomorrow I take the car to Shaun at AED Tuning. He has been awesome on the phone. Also, he is only 12 miles away and a west-coast Coyote expert. So I want hands-on troubleshooting. Meanwhile remote LUND tuning only goes so far.

First oil change Coyote details

Gasoline smell thins the oil

So why change the oil? Well, all these startups left a strong gasoline smell. As a result, gasoline can thin the oil viscosity. Then the film may fail under load and speed. Friction follows, and parts wear. Hopefully AED finds the issue. After that we can dyno tune. Besides that, fresh oil keeps the engine happy!

Parts list for 10.5 quarts

So what did I use for the oil change? With the Gen3 Coyote and Moroso pan plus a new filter, it needs 10 1/2 quarts. Here is my list:

(1) Mobil 1 M1-113a Extended Performance Oil Filter.

(2) Mobil 1 Advanced Full Synthetic Motor Oil 5W-20, 5 Quart.

(1) Mobil 1 5W-20 Advanced Synthetic Motor Oil – 1 Quart for that extra 1/2 quart.

(1) Moroso- 97010 Copper Crush Washer.

Drain, filter mess, and refill

It is not a hard process, at least without the body on. First I jacked up the front. Then I set a 16 Quart Oil Pan under it. Because you need room for 10.5 quarts. Next I used a 3/4″ socket on the magnetic drain plug. After that I let it drain. It takes a while!

The oil filter was a total mess. My whole forearm got covered in oil. It has been a while since I did my own change. Still, the Coyote holds at least a quart up front. Therefore bring Scott Blue Shop Towels in a Box!

Once I wiped everything, I sealed the pan with a new copper washer. Then I installed the new filter with a little oil on the gasket. Next I refilled with a Flex Funnel with Hose. Because the Coyote filler gets tough once the body is on. I checked at 10 quarts. Likewise, it sat at the bottom of the dipstick hash marks. So I added the other 1/2 quart and it was perfect.

Hopefully tomorrow will be a great day to drop off the car!
