Thanks all for the reply!

But even if there would be little difference in the amount that sticks between Dino and Synthetic, the disagreement as to whether the wait should be 5 minutes after warm or cold in the morning disturbs me. So far, I haven't been able to park the car for hours on level ground (both at home and at work the parking had been on an incline), so I'll have to try the cold method deliberately. I think I'll park the car level (like at the mall) and check 5-min later and several hours later and see if the level is the same. If it isn't, then at least one school of thought regarding how long to wait has to be wrong....
