Ding ding ding we have a winner!!! The only way to know when YOU should change YOUR oil is to get it tested by these wonderful people at blackstone. Pay $25 for testing or pay $1,000’s after engine failure. Your call, chief. We all drive our cars differently and we all live in different areas and we don’t all drive the same amount of miles each year.I prefer going with the Experts.
A thing of the past? with turbos, direct injection, intake valve deposits, timing change wear, GM recalibrated the OLMs for shorter change intervals due to these concerns, sure the oil will last but the additives will break down the longer you keep it in the oil pan. No thanks i'll stick to my 5K intervals.Changing the oil every 5000 miles is a waste of money since there is still a lot of life left in the oil. In addition to that, twice as much used oil is disposed of which pollutes the environment.
A 5000 mile oil change interval is a thing of the past because motor oils have advanced tremendously since then. There's a reason the oil life monitor was created for today's engines; because motor oil has been reformulated to last much longer today.
