I LIVE FOR THIS
What makes this stuff better than their regular 5W-30? Series 2000 can go 35K or 1 year oil changes and regular 5W-30 can go 25K or 1 year changes. Now ive red many post regarding extended oil changes and they always come back saying that oil becomes thicker over mileage time. With that being the case will the Series 2000 become a 5W-30 over mileage time? Thanks.
