My car shows service required, and the engine is making a high pitch noise.
Today's Sunday so i cannot get it checked,
but I need to pick up a friend tonight, about
40 miles. Is it dangerous to drive my car
onto highway? How bad is it for my car?
who knows? you have an expensive Jag, and I wouldn't take any chances- can you just rent a car?
Ditto to what J.B. advised you. Don't chance it.
Thanks, I'll tell him to find someone else or get a cab.
Good choice on a cab, like every one else said Don't risk blowing your engine.
