Hi all,
So I am wondering what the actual change interval on Mobil 1 oil is. I run Mobil 1 high mileage on a few vehicles and normally change the oil at 5k, along with the filter. As of late I have been using Fram Synthetic filters and read that they can be used for up to 15,000 miles. So now I am thinking I am changing my oil and/or filter too often but being paranoid and all I wanted to see what the consensus was on the forums. Perhaps just changing the oil at 5k-7k and leaving the filter for 10k? Thoughts? Cars and SUVs see mixed highway and city driving. One of the cars tends to get into stop and go traffic on the highway.
