In my effort to try out different big-name 0W-40's in my K20z3 engine, this was my first run of Castrol. I would have liked to fed it more mileage but by the time I drained it the oil had 15 months of service on it and I prefer to stick to 12 months if I can help it.
Make-up oil was Mobil1 5W-30...I have a few straggler quarts around the garage I'm trying to use up and I imagine this brought the viscosity down a touch.
Standard OEM Honda A01 Filter (last one, moving over to Fram XG7317 Ultras next), and this engine gets driven hard and sees a trip to fuel cut in a gear or two nearly every day which is part of the reason you see a quart of make-up oil. Mixed use in everything from highway driving to a lot of stop/start around town and a few aggressive backroad drives. Pleased with how this performed for the money and will probably stop sampling at this point - its getting too predictable! I'll just pick up whatever of these brands are on sale...can't go wrong.
