This is a winter short trip galore UOA. It is not great but I dare say that I am not killing my car's life span by doing everything bad that I could concieve of! In fact I even used insanely high dosages of fuel injector cleaner just to make it the worst case I could think of. I had a lot of trips under 1 mile and I had insane amounts of prolonged idling! It is not that bad! Use a decent synthetic and let the rest sort itself out.
