Current revision

The Datsun 1200's A12 engine uses a standard gerotor type oil pump. It is self-priming. The oil should be changed every 3,000 to 5,000 miles.

Overview

Oil Temperature

The oil temperature is controlled by the engine coolant temperature. As long as the engine coolant ("water") does not overheat, neither will the oil. Only a very few high performance cars have a separate oil cooler. So this means:

keep your coolant temp low, and your oil temp will be happy.

Count on the oil temp to be about 20 F degrees hotter. So here is a good street performance equation:

* Thermostat: 180 F degrees
* Oil temperature: will run about 200 F degrees

At this temperature, the good quality regular oil (inexpensive) will perform as good as the expensive synthetics in a street car. It is high temps that ruin regular oil whereas the synthetic oil can take high temps OK.

Now if you are racing or towing there is more to talk about. See: Oil Pump Coolers.

Engine Oil Capacity

See Oil Capacity 

Oil Pressure

From the 1973 factory service manual:

* Oil pressure at idle (650 RPM ): 13-17 psi
* Regulator valve spring
  Free Length: 43.49 mm (1.71 inch) 
  Pressured Length: 30.3 mm (1.19 inch)
* Regulator opening pressure: 54-60 psi

Oil Usage

It is normal to add some oil between the oil changes. Usually a quart every 1,500 miles is OK. A quart every 500 miles indicates either a serious leak, or "oil burning" (bad rings) in the engine.

Oil Guages

Interchangeability

All A-series oil pumps are interchangeable in any A12/A12A/A13/A14/A15 engine, except the early A10 Engine oil pump. New pumps will clear the early A10 Connecting Rods.

• connecting rod cap strengthened with 1mm longer bolt boss starting with A10-728641
• Therfore, Oil pump driveshaft decreased 1.5 mm to clear the new cap design
