Advice on oil change frequency
Asked by xbwave Jan 17, 2018 at 10:36 AM about the 2004 GMC Envoy XUV 4 Dr SLE SUV
Question type: Maintenance & Repair
Hello I drive a 2004 GMC Envoy XUV, has a 4.2-liter, 275-hp 6-cylinder engine
and is RWD. I'm wondering how often I should be changing the oil. I have a
long highway commute so I drive at least 166mi total per day. Right now has
88.5k miles on it. I've been going with full synthetic in hope to go longer
between oil changes, how often would you all advise taking it in for a change?

If you like your car and plan to keep it change the oil every 5,000 miles with synthetic. This is a lot cheaper than a new engine.
@tennisshoes Maybe a little, what does that mean if so? Also thanks!
If it were mine I'd change it at 7,500 miles or 1 year whichever comes first. If you do lots of in town stop and go traffic driving then I would do it at 5,000 miles or 1 year. Also synthetic oil is not necessary unless the manufacturer recommends it or you have a turbo charger which you don't. Synthetic oil is a better oil, but I doubt there would be any noticeable long term benefit in the vehicle you have. Today's engines and today"s oils go much further between changes than in years past.
