I used to be chairman of a municipal electric utility.

We always ran electric heaters in the oil tanks for Fairbanks OP 12 cylinder 24 piston turbo/supercharged 2 stroke diesel motors. The tanks held 250 gallons of oil. It allowed the motors to come up to full power in 20 minutes vs a 2 hour warm up time with cold oil.

A lot of current (and even slightly older) Mazda and Ford passenger cars use an oil/coolant heat exchanger which both cools the oil when it's up to temp as well as heating it up faster when it isn't. Attached is what the basic assembly looks like (black part is the exchanger, green is the oil pressure sensor) as well as a quick and dirty cooling system map for my car (2009 Mazdaspeed 3).

The cooling system map may not make much sense but the basic gist of it is that the coolant comes out of the head, goes into the heater core (which has its own internal bypass), comes back out and goes into the oil cooler, which then dumps back into the thermostat housing where the flow cycle starts all over again. These cars use a constant mix of radiator coolant as well as engine block coolant but never draw 100% from the radiator (which is pretty small as it is).

Hope this helps you find more options.

Yeah, the turbo. I wasn't exactly in my right mind when I drew that thing up.

Actually they are, on many police cars, turbo cars and HD trailer towing options. My 92 Crown Vic police had one, as did my 84 and 86 Mustang SVO, 87 Thunderbird TurboCoupe, and my 94 Thunderbird Supercoupe (and my 86 Ford E350 diesel van, but a different design).

Hmmm, it's under there somewhere:

The obvious is that the jacket (you know, the bit around the cylinders that coolant flows past to cool the oil and cylinders) is already a heat exchanger.

Insulate the oil pan which will reduce temperature loss via the momentum of the vehicle moving (or just to the ambient low 'merica conditions).

The jacket isn't as efficient as the plate heat exchanger in the OP, but that will also function to cool the oil (essentially bringing both mediums to the same temperature, and if left in would heat the coolant up, thus forcing cooling to be required too - i.e. your oil will also only reach up to whatever your cooling system is over engineered to cool to).

I agree with insulating the oil pan being the first step. If your car is FWD and the exhaust runs underneath the oil pan, you can rig up something to block that exhaust heat from being whisked away so easily as well.

I think the exhaust heat is going to be the fastest way to get the oil temps up. Even manufacturers are looking into utilizing wasted exhaust heat these days.
