-	Use the [[L|L-series engine]] oil pump rotor and stator, which is exactly the same as A-series parts, but longer. This requires a spacer to make up the difference. It also requires modifying the shaft. Use the larger diameter L-series shaft pressed through the rotor and re-pin it for the A-series gear. Run a 1/2" reamer through the A series housing to make the L-shaft fit.	+	{{Photo!|15050-18001.jpg}}

-	High-volume is more important than high-pressure because it ensures oiling. The NISMO pump uses high-pressure (100psi) which will also work up to a point, and is far simpler, only requiring shims on the pressure valve. But the better, more expensive option -- if needed -- is the high-volume pump. Most built A-series engines do not need either high-pressure nor high-volume pumps.	+

Some have reported that the Datsun Competition two stage pump on turbo engine only just has enough presure when the oil is hot and at idle (10 PSI) and that is with a ball bearing turbo that needs a lot less oil than a floating bearing type. But in general the reserve capacity of the standard A series pump has enough capacity to maintain good oil pressure with a turbo and hot oil.	+

-	Also, performance motors are generally built with clearances purposely on the large side, thus more leakage of oil when operating and the risk of dropping pressure.

-	Baffled sump is to help keep the oil in the bottom of the sump even with high G-forces of racing. So a high volume pump is not needed for that.	+

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 Pressure Sender

Oil Guages

Oil Temperature or Oil Pressure gauge can be added.

Oil Specifications

Oil Usage

See Engine Oil Specifications

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
