100,000 Maintenance, is this normal?
Hi all,
I purchased this 2015 F-150 about 3 years ago. It hit it's 100,000 mile maintenance and I took it to a local mechanic who I've used for decades. In the photo then upper left is the coolant, the middle one is the transmission fluid and the one on the right is the rear differential. The coolant doesn't look too bad to me. But the transmission looks burnt and the diff looks .. rusty (?). Everything has been flushed and refilled. What do you think I should do? Nothing, or sell the beast?

100k maintenance should be done at 50k miles in my opinion. All of those fluids look normal for as old as they are. How does the brake fluid look? It should have been flushed too. And what about the spark plugs?

No need to shop for a new truck if the one you have is running fine.

I can tell you the ULV transmission fluid will look dirty within 15k miles. At 100k it must look horrible.
The coolant and rear diff fluid also look good to me.

If the vehicle was running fine and wasn’t giving you any problems before the service and since the vehicle is almost 8 years old, just have the next full service done at 50K as JK mentioned.
No need to get rid of a perfectly fine running truck.

Thanks all for your comments. The truck is running fine, except for a problem with the head unit disconnecting Bluetooth with my phone. I doubt if any of the fluids are to blame for that. The spark plugs didn't look bad, although they were original. The gaps were greater than they should have been. Perhaps worn? I checked the transmission and differential for chips and didn't notice any, or feel any grit between my fingers. I didn't do the brakes ... have to think about that I guess.
