Oil Changes on a 2009 Chevy Malibu

The oil change reminders are for the most part, bunk. If you’re going near 10k miles without changing the oil you have shortened the life of the engine.
Ever heard of engine sludge? Well, oil change intervals like this are the reason for that.

You can go 5k miles between oil changes if most of your driving is on the open road. If you do a lot of short hop, stop and go stuff then stick to the 3000-3500/3-4 months interval.
If your driving is REALLY extreme and the enviro conditions are applicable then even 2500 miles/3 months might be called for.

I recently saw some pics of an '09 Cadillac engine that seldom saw an oil change and you should have seen that poor engine inside. Nothing but swamp muck and one couldn’t even make heads or tails out of the timing chains or valve train.
