When it's cold, like under 35 degrees now...should you let the car sit and idle for a while, like 10 minutes to reach normal operating temperature or just start it, idle for like 2 mins then drive slowly to get it to temp..?
The 4.6 in my thunderbird takes along time to heat up, this is normal for thunderbirds..but i'm just wondering if it's better to sit there and waste gas for ten minutes or just drive it easy until it heats up.
PS i read somewhere that just idling doesn't heat up the oil like driving it slowly...is this true..?
