Please review these recommendations for using OrganicĪdditive Technology (OAT) engine coolant (antifreeze) MS-12106) throughout the life of your vehicle. The same engine coolant (OAT coolant conforming to To prevent reducing thisĮxtended maintenance period, it is important that you use This engine coolant (anti-įreeze) can be used up to ten years or 150,000 miles Your vehicle has been built with an improved engineĬoolant (OAT coolant conforming to MS-12106) that allowsĮxtended maintenance intervals. Changing the coolant more than every two years is probably wasteful, but more than 5 and you're accepting a consistent level of system degradation as normal. It's NOT sufficient to maintain the vehicle in perpetuity. As I get more familiar with the Patriot, it's becoming more and more clear that the service intervals are designed to do the minimum maintenance in order to survive a reasonable product life cycle. Regarding the service life of the fluid, I don't recommend following the 10 year interval.

Anymore you'd be hard pressed to find an automotive coolant of any color containing alumina corrosion inhibitors, so color doesn't matter. The orange/red/yellow coolants were introduced containing sodium or potassium corrosion inhibitors, since both of those are more reactive than aluminum. As aluminum engines became more common, the alumina in the coolant wasn't sufficient to prevent corrosion.

Green antifreeze used to have alumina corrosion inhibitors, since aluminum is more reactive than iron, the alumina in the coolant solution would oxidize instead of the iron engine components. It's worth noting however, that industrial organic chemistry is a big, money making field so the technology it produces tends to be pretty reliable ('organic' in this context means elemental carbon based molecules, not tree bark and coconut oil). OAT is purely a matter of compatibility, not protection or performance. I'm going to go a step further and say that if you don't KNOW what's in there already, you should flush and fill with new so that you do know what's in there.
