John,
Are you using the water from the race engine or from the push truck? I
prefer to preheat without running the race engine.
I have been researching a method of preheating the oil. I have found an
adhesive blanket 6"X12" which is the size of the bottom of the oil tank.
It is 120 volt 180 watt unit. Have you or anyone on the list used one of
these blanket type heaters. If so, how effective are they.
