A question for you guys: is it possible to harm the vehicle by starting the vehicle too infrequently? I live in a metropolitan area and have two vehicles. I drive the old little compact car around town just about every day here and there on short-trip errands--not too worried about that one. But I leave the 4Runner in the garage (which gets to 100 degrees or more most days in the summer, and around 20 degrees on most winter days) for a week or so at a time without starting it, and drive it only on longer highway trips when I do use it. I have always done that with the newer SUV both for gas price reasons and because I figured the less short trip miles put on, the longer the vehicle lasts. Lately though, especially with the sizzling weather we have been having and how hot that garage gets, I have been wondering if there is perhaps some hidden damage being done to seals, gaskets, etc. by sitting in the heat for a week or so at a time unstarted, as well as possible consequences of starting the thing only once a week or so. I suspect that oil flow at start up should be a particular concern for me in this situation, but other advice as to have to ameliorate the damage? Or do I need to change my mind on driving the 4R? Is such a regiment actually doing more damage than good? Anyone given some thought to issues like this and have some good insight? Thanks!
