Hope the weather cools off for a weekend so I can try these tires in the dirt.
Hi way wise, I'm starting to hear the tread, but it's not obnoxious, a low hum when the windows are down.
However, traction on road compared to the AT's, definitely less tread on the ground and the sidewalls seem softer
We'll see how they "break in".

Oil change w/Mobil 1 and Microguard filter because that's all they had at O'Reilly's.

Should have taken 20 mins to do, but the last person who put on the filter used the 1,000 lb./ft. setting. I had to drive a screwdriver through the filter, then hammer a 12" pry bar through it, just to get it to spin. Then the giant channel-lock pliers I had were enough to spin the thing off. What a nightmare. But hey, now that's done.

Question: after resetting the dash monitor for oil change life, how long is the computer programmed to go between intervals? Is it strictly mileage based, or is there a formula for engine hours & miles factored together with fancy maths?

I change mine every 5k miles (with Mobile One full synthetic), and ignore the oil life monitor.

It factors other things along with miles but I don’t trust it.

Okay, good to know. The oil came out looking dark, so I wonder if the interval should be less.
I believe the DTC oil life eminder is supposedly taking into account driving conditions, etc. I tested it a few times and it never got down to triggering a reminder in less than 9K miles and the oil was always very dark before the reminder, so I quit using it and went back to 5K mile interval for oil and filter change.

That's the new plan.

Talk to me about your headlights. Your sig image is cool; what are they?
That’s weird that it went to that high a mileage. My NBS always triggers right around 3k but I drive it hard. I never noticed on my NNBS Silverado because so far I’ve only changed oil once, 2000 miles after I bought it. I’m not even close to another 3k.
