If I run Mobile 1 Full Synthetic in my Regal (haven't even had my first oil change yet) how many miles should I be getting between changes?
Should I be changing my filter more often (lets say every 5k miles) since I will be able to go 8-10k+ miles?
Or do I not have to worry about it on a modern car like the Regal?
Mobile 1 FAQ says NO on extra filter changes
If I go longer between oil change intervals, do I need to change my oil filter more frequently? Or do I need a special filter?
Continue to change your oil filter when you change your engine oil. Special filters or more frequent oil filter changes are not required;, however, some low quality filters may not be capable of protecting your engine throughout an extended oil change interval.
Mobil 1 Extended Performance Oil Filters provide outstanding protection during longer oil change intervals - up to 15,000 miles of Guaranteed Protection when combined with fully synthetic motor oils. Mobil 1 Extended Performance Oil Filters are designed to remove more impurities (99.9 percent Multi-Pass Efficiency Test rating) and hold more contaminants (22.5 grams capacity) than conventional oil filters, which make them ideal candidates when oil drain intervals are extended. All new car warranties remain in effect when Mobil 1 Extended Performance Oil Filters are used. Follow your vehicle manufacturer's recommended oil change intervals.
