Filler tube, dipstick, oil filters to start. You reckon the quality help at Speedco worries about the buildup around the filler cap or dipstick? Are they worried because they couldn't see the filter bases and God knows what fell into the oil filter in their 6 attempts getting it onto the threads?
You reckon they're cleaning the buildup off and wiping off their fingers before they pull a fill plug on a diff or trans and finger around for the fluid level?
