I'm currently using Havoline 5W-30 dino with PureOne filters and I think this is a very good oil/filter combo. However, I put a lot of miles on my '99 Corolla (approx 3K a month), and I'm thinking about switching to a full syn to extend my OCI's. My current OCI is 6K and I'm thinking about switching to the 15K Mobil 1.
One thing I like about my current OCI is the oil never gets black. I know the oil turning black is not a sign that's it's broken down or it's not doing its job, I've always just had that "warm fuzzy" by not allowing my oil to turn black. If I were to go to the 15K OCI with the Mobil, is this oil going to turn black on me? Please help me get over my ill-driven black oil phobia.
Since I would be extending my OCI's by almost 3 times, I would probably also spend the extra money on the Mobil 1 filters as well.
Would there be any down side for me going this route?
