I'm not in Australia. There are not many commodore in my country. "service engine oil" came on my monitor and I'm so affraid that I don't want to start my engine again. The manual I have doesn't have the meanings of this warning. It has just the meanings of "check oil" which tell that the oil pressure/level is low. I've checked the oil level and it was nearly full. I've called the dealer. They said they will come to my house on monday to check the engine. But, I'm just so worried about my car's engine. It's calais vz 3.6, 8,8xx km.
