I let the engine idle for 5 minutes before checking the fluid level. The instructions in the car manual said let it idle for a few minutes and then check. It was below both marks after checking on a 5 minute idle.
What should i do next? I don't want to drive it for 20 minutes when theres a problem. I have an appointment with the tech monday, but what else can i do until then to try and find this problem?
