I'm getting ready to do my annual oil change on three Chevy Silverados which average approximately 3-4K miles each on average freeway and surface street driving here in Los Angeles. I've been using Bosch Premium oil filters and GC with great used oil analysis reports. I recently purchased Bosch D+ oil filters from Amazon and GC from AZ to complete the oil change. I plan on doing my annual oil change this time using the D+ oil filters for two OCI across two years. I've noticed that the distance (time/mileage duration) in "Distance Plus" is not clearly defined on the oil filter packaging or noted on the Bosch D+ wesite. Is going two years to long with a Distance Plus oil filter?
