Did an oil change today. Filled back up with Valvoline Prem. Blue 15W-40. Put in first two gallon bottles... ... . when pouring in the 3rd gallon, I noticed the oil was much darker than the first two. It also had a different smell.
All 3 bottles had the foil seal intact.
Anyone seen this before? Do you think it's a problem or a need to change the oil again? Engine is running fine.
cheers,
Sean
