Terrain? I have a 2002 Pontiac Grand Prix and also a 2010 GMC Terrain. The Terrain gives a percentage of oil life left, while the grand prix does not, but is everything else about the system the same? I want to know whether I can trust the Oil Life Monitor on the 2002 Grand Prix since it hasn't ever gone off since I've had it. I've always gotten my oil changed between 3000-4000 miles. Thanks for your help!
I do a lot of highway driving in temperatures ranging from -20 to 90, if that helps anyone.
