Dear God. You are living on borrowed time with that car buddy. You must have made a deal with the devil to get that car to 236000 miles.
With proper maintenance, I have owned vehicles with over 300,000 miles. 236,000 highway miles is nothing with today's cars if they are maintained well. When you get in the car, put the key in the ignition and turn it and nothing happens.....that's a good time to retire your vehicle.
I have a 1987 t6000 and it wont die I stop changing oil a few years back and that wont kill it
