The only part you all got correct was that the cooler operating temperatures creates more wear. The year is 2017. wrench

Today's gasoline requires 195 DEGREE MIN OPERATING TEMP.
It is not the same fuel as in 1970. If you do not run the engine hot enough the fuel will collect in the intake manifold and burn off n the cruise mode, flip flopping the air fuel ratio. This is not conjecture, hearsay or i read it on the internet, but information from instrumentation and years of tuning experience. Ethanol laced fuel requires a different tune up that non ethanol fuel. the A-F ratios are different......gee wilikers Mr Wizard... help

60% distilled water 40% antifreeze and a bottle of coolant additive.

If you guys would pay attention and retain just a little knowledge this forum would be a better place. up

195 is not hot
210 is not hot
195-210 is the normal operating range where your car should run
220 is warm
230 is hot
