Hi. I bought my turbo '94 850 wagon this summer with 120,000 miles on it. It has driven just fine so far. I live close enough to work to come home at lunch and I decided to check the oil before heading back to the office (it's just at the 3000 mark). The oil on the dipstick was brown and foamy. Talk about a butt-pucker. I don't know much about cars, but I know that's a bad sign. I twisted off the oil cap and the oil inside was black and beautiful. The coolant was bright green. The car starts up and runs fine.

I have been doing some reading on the board and I know that short distance city driving can lead to condensation. I drive maybe 10 or 12 miles a day, all in town. I would like to take the car out for a nice, long highway ride to see if I can straighten out the mess before I head to the mechanic, but I am nervous that driving in this condition could hurt the car, especially if I'm not just paranoid and there really is a blown head gasket. Anyone have any advice for me?
