So my Toyota is running better than ever. Almost 34 MPG at my last oil change. :) I ran the ARX about 30K miles ago, and have been on a maintenance plan since. I was running Pennzoil Yellow bottle for the longest time, and have switched now to the Mobil 5000. Car is driven about 110 miles a day, and I have been religious about changing the oil at 3,000 miles given the harsh Minnesota winters.
My question is - can I extend the Oil CHange INterval to 5,000 with the Mobil Super 5000 oil? REcommendations/
