My truck has 292,000 miles on it. I get the oil changed around 7,500 miles. Not synthetic.
The owner's manual suggests every 3,000.
That is bs.

Glove box: owner's manual, tire pressure gauge, u-haul adapter, and paperwork that came with the truck.
Trash goes in the trash can (Reed Arena popcorn bucket)
Koozies - seat pockets and doors.

Console: Owner's manual, insurance, miscellaneous girly stuff & a few cozies

Under seat storage/safe: nothing at the moment

Upper glove box: extra ear plugs for the range

Lower glove box: Coggins papers on the horses, window sticks from truck purchase, napkins, pen.

Driver's door pocket: Master locks, zip-ties in various sizes, butt connectors, fuses, electrical tape, trailer light adapters, skinning knife, tire pressure gauge

Driver's side backseat door: 1qt motor oil

Driver's seatback pocket: US Atlas, Texas road map

Passenger door: nothing

Passenger backseat: SportDog 800 + charger & remote

Trash usually accumulates in the cup holders until I have an empty fast-food cup, where all the trash gets shoved in the cup and thrown out.

In this day and age, why put regular oil in your car?!??

Bigger diesels run better with regular or so I've heard. My husband cummins uses regular.
