Seen this done with good success.
Take the tank and have a 1" NPT bung welded in the bottom first few inch side wall and a 1/2" NPT bung welded a few inches down from your running oil level. Then purchase a 12 volt -300 watt fluid immersion heater (1" NPT) from Dermond for about $25 on Amazon and purchase a bulb type adjustable thermostat 1/2" NPT threaded from Stemco.
Wire the pieces with #10 or #8 wire (25amps) and set the thermostat to keep the oil at about 150- 160 degrees with engine off. This should keep your oil temps at a sweet spot until your ready to blast.
Back in the 90s, when we were running lard for oil, temp was such a big deal, I had 6 500w probe heaters in our oil tank. That way, if we got "delayed" in the tech line, proper oil temp could still be reached for qualifying. It would take 3 gallons in the dry sump tank from 100* to 400* in 10 minutes! Lol
Lard for oil. CLASSIC. I can't imagine what it was like in the 70's and 80's!

Had to be a well funded team.

The smells on pit road during qualifying. Boiling oil from the 2000 watt dry sump heaters. Haha.
I installed a single wrap around style (120volt) on my 4 gallon tank.I plug it in at least 1 hour before I race to get the temp to 130.I was on the dyno once and forgot to unplug it and left it on all night.It was 150 the next morning.We are all accustomed to discussing oils by weights ,but I think centistokes will give better information.
In the engines we are using and discussing it seems the Kinematic viscosity is the major type we are dealing with and is the resistance to flow from being forced through an engine versus flowing just from gravity as in Dynamic viscosity. So this Kinematic viscosity should be expressed in centipoises , cTp not centistokes, cTs. Am I mistaken here or just confused.

My knowledge of viscosity is in centipoise as that's what's use in drilling mud and slurry walls for geotechnical applications.
Dynamic viscosity (cP) / Specific gravity = Kinematic viscosity (cSt)
The more reliable metric is cSt since oil viscosity may change at the same density. Air aeration will have an
extreme effect on oil viscosity measured in cSt.
The Sommerfield number is often used by lubrication engineers to predict which oil should be used.
The necessary inputs for the calculation are:
Bearing clearance
Bearing length
Bearing load
Bearing speed
Oil temp
Oil viscosity
Oil specific gravity
Oil pressure
The equation is used to determine the minimum viscosity that can be used without inducing accelerated wear.
It can also be used to determine the limits of any other variable such as speed, load, clearance, etc.
It soon becomes clear that various parts of an engine will have different lubrication requirements.
