Motor oil

Background
There are two types of oil plans for the 850 (with different capacities) depending on engine type, see table below:





Version 2 has fluorescent dip stick handle (version 1 is red)
When replacing oil filter only: Top up with 0.5 l oil.




850 cars with the B5254S engine (automatic transmission) have been equipped with a larger capacity oil pan for engine oil, from engine serial number 374783.
From chassis numbers:
Factory code 1: 854-205080
Factory code 2: 854-206644
Factory code 2: 855-106997
The change effects the amount of oil used at oil changes and when topping up the engine oil between the Min/Max levels on the dipstick.
Capacities - B5254S engine, with new sump.
- Oil and filter change 6.1 US qt. ( 5.8 liters)
- Oil change separately 5.8 US qt. ( 5.5 liters)
- Replacing oil filter separately 0.4 US qt. ( 0.4 liter)
- Volume between Min./Max. 1.6 US qt. ( 1.5 liters)




The engines with larger oil capacity can be recognized by the color of the dipstick handle. The dipstick handle is fluorescent red.




The dipstick also has a disc attached to the handle.
The text on the disc gives the difference in volume between the Min/Max markings: "Between Min/Max 1.5 l (0.4 US GAL) " .

OIL GRADE
As per API-serviceman SG*
As per CCMC class G4/G5
* Oils designated SG/CD meet this requirement.

Oil pressure (min)*
13.3 rps (800 rpm)MPa 0.10 (14 psi)
14.2 rps (850 rpm)MPa 0.10 (14 psi)
66.7 rps (4000 rpm) min MPa 0.35 (49.8 psi)
66.7 rps (4000 rpm) max MPa 0.70 (100 psi)
Max oil pressure (relief valve opens):MPa 0.50 (71.1 psi)
Turbo: Max oil pressure(valve opens)MPa 0.60 (85.3 psi)
(1 kp/cm2 approximately 100kPa approximately 0.10 MPa)
*Oil pressures apply at an oil temperature of 100°C, which is reached after 10-15 minutes driving with the B 5204, B5252, B5254 and B5234T.
