Changed my oil today. Used Rotella T6 I bought last fall. Using a black funnel, I poured in about 3.5 quarts of oil. I then realized the oil was as black as my motorcycle. Somebody obviously returned the bottle of Rotella after filling it up with their used oil. When I uncapped it, it was on tight and even had a couple audible snaps from the security ring.

I drained then dumped in a few quarts of miscellaneous oil I had laying around the garage to clean out the crud.

Typing this while draining one last time. I double checked the new gallon of Rotella, real close this time.

I hate asshole scumbags.
