[QUOTE="jimdawg185, post: 1485742, member: 757"] That's different for every oil, but 500 degrees is about the average flash point. That's not really much concern. It's the oxidative breakdown at 280-300 that begins to accelerate. And believe it or not, the mineral based oils actually have an advantage in a peculiar way. Granted, not much oil that's called a synthetic actually is any longer. It's mostly group 3 mineral. But that's beside my point. Mineral base oils have the tendency to resolublize varnish. Where Synthetics can't because the nature of the molecule. It's very complete so it's more robust, but that also keeps it from solubility. That's why really good PAO Synthetics are so expensive. The base oils are not cheap, but you also need a great carrier stock, a special add pack, and esters. Mineral base oils will soak up that crap, to a point, then they sludge up badly quickly. It's six of one, half dozen of the other. Best practice is to change the oil often if you're working it hard. If you drive a lot and want to extend drains under those conditions, you need analysis to verify the contamination and oils oxidative life. Sent from my iPhone using Tapatalk [/QUOTE]
