Thx jay, I knew there was a good reason to not waiting aroudn for it to warm up. Someone told me once and I completely forgot .. and I have all these friends who claim to know about cars and say how its soo important to wait for it to warm up and people who dont do it are idiots. I can finally explain to them why they are wrong.
