Oil gage at 78% in 2007 tahoe when to change oil?
If you are a normal driver then I recommend you change your oil/filter every 5,000 miles if you are using conventional oil. If you are using synthetic oil then change every 7,000 miles. Just as important is to use a quality filter such as AC/Delco, Purolator, or Wix. On your GM vehicle I would use an AC/Delco filter. Another very important filter is the Air Filter. Replace this filter every 30,000 mile unless you drive in very dusty conditions, and if so every 20,000 miles.
