I put the bottle of STP in a pan of hot water while I am doing the task. Then add it last as it pours easier after being warmed up a bit. In the summer I can just set it on the driveway to heat it up here in Arizona.
After doing this four times I have four qts. of oil saved up for another oil change. Just the way I do it... Chap

I guess since the original question Don asked has been answered, let me ask you why you feel 10w-40 with the added expense of the STP is your preferred weight over something such as 20w-50, ...or even a different weight all together and just use a straight 30 wt?
