After reading the pelican article about regular coolant, I decided to go with OEM coolant. But didn't expect to be ripped off at $30 bucks per gallon, That's 4x more expensive than the regular green stuff. Oh well, guess my car deserves it. If I didn't have to replace my thermostat, I would just give it to the dealer - they're having a radiator flush and fill special for $69.00. Sorry , just had to vent.
