That is a Question that will draw Much Debate and Many Answers, let me start with this.
Synthetic oil is proving to be a superior lubricant for all engines. It not only lasts longer but also creates far less "sludge" and other buildup. Engine sludge is actually paraffin, much like the wax that is used to make candles. The paraffin breaks off of an oil hydrocarbon chain and bonds with other paraffin molecules, until you create a large amount of sludge inside the engine.
Regular oil changes can slow the process, since the paraffin molecule typically starts to break off after the oil has been used for a while. But since the paraffin has been removed from the synthetic oil, you'll end up with a far cleaner oil, plus the oil will not break down for up to 25,000 miles, giving you far superior lubrication inside the engine.
While synthetic oils make claims to last that long, most people never use it for much more than 10,000 or 12,000 miles. But even then, it's far less expensive since you're changing less often, and you still have the advantage that it provides superior lubrication. The more reputable auto manufacturers will not specify a brand of oil, but will indicate the viscosity and request specific engineering certifications.
Look at the top of the oil can/bottle for the engineering specification stamps, and read the owners manual for the recommended viscosity. All oil manufacturers offer you a choice of oil viscosities.
In the newer GM automobiles like the GMC Canyon they have an Oil Life indicator that displays on the dash when you have reached what they consider to be time to change your oil. This generally happens around 10,000 miles.
---- If you are not comfortable with going say 25,000 miles/1 year then you can always go with a 7,500 Mile/6 months, with Amsoil Motor Oil.
On a MPV I believe the recommend viscosity is 5W-30
Hope This Helps.
