Hi, I am currently living in the middle east and own a Toyota Prado (diesel). I sometimes go on business trips for 3-6 months (some times more). During that I time, I store my car in a garage. I was told that it is not good for the engine not to run for such a long time. So, I asked someone to run the car for 5-20 every week and it has become a problem finding a reliable person to do that. Another mechanic told me just disconnect the battery and go. Nothing will happen to the car. So, which suggestion should I follow? Thanks for your help.
