On Friday night I was driving to dinner and about 4 miles from my destination my Low Oil Pressure light would occasionally blink on for a second. I thought I would just get to where I was going then try and solve the problem. I drove the rest of the way there and by the time I ate dinner I completely forgot about the issue. The drive home was about 8 miles (freeway driving) and probably 2-3 miles from home my Check Engine Light came on and my Cruise Control light started flashing. I drove the rest of the way home and parked it for the night. The next day I checked my oil and it was VERY low so I walked to the gas station and ended up adding 3 quarts of oil. Now my Check Engine Light is still on and the Cruise Control light is still flashing and I don't know how to turn it off. The car sounds normal, and while driving it feels like it is in the "Intelligent" mode. My question is, what am I supposed to do now? Do I just keep driving with the CEL on, or should I disconnect the battery and see if it goes away? Should I be trying to get to a dealership? Is the engine ruined and I just don't know it yet?
