I've switched over to the High Mileage oil. It's a bit more expensive, but with the amount of miles on the truck I guess a more suitable oil won't hurt.
Thanks Nick...I'll use the 10w30 in the summer.
Keep us posted as to if it uses less oil or notice any change. I think it's a better fit considering the miles on the truck. The only thing better is the Signature Series and that is way more expensive.

I'm just a couple 100 miles shy of 3,000 miles and normally I would be adding a quart of oil. The level on the dipstick is just above the first hash mark. So, I guess the high mileage oil is helping some with my oil consumption. I've been driving the shit out of my truck the last two weeks putting over 100 miles a day with speeds ranging from 60mph to 80mph.
Thanks Nick! :cheers:

That's good to hear. Over time, hopefully it will slow it down even more as it cleans up and helps the rings seal.

You're using the signature series and changed it at 5K. I'm about 200 miles shy of 5K using the high mileage oil and want to change it.
With all the DFM lifter issues, I'm hoping keeping fresh quality oil in will keep me safe from one going bad. You don' have that issue.
