I asked this question a couple of weeks ago in the Euro Moto Oil Section but didn't get a response. It appears that Castrol no longer has available their specially formulated for Jaguar/Land Rover Edge Professional EC5 0W-20 oil. When I had my Jag in for service they used Castrol Edge Professional LL IV FE 0W-20. It no longer carries the notation on the back label that it meets the Jaguar/Land Rover STJLR.03.5006 (ACEA C5) standard, but , curiously it says it meets VW's 508 00 specification.
Here is what the data sheet shows on that oil:
Castrol EDGE Professional LL IV FE 0W-20 is suitable for use in automotive gasoline and diesel engines where the
manufacturer recommends an ACEA C5 0W-20 lubricant.
Castrol EDGE Professional LL IV FE 0W-20 is approved for use in vehicles that require a VW 508 00 / 509 00
specification 0W-20 lubricant.
Castrol EDGE Professional LL IV FE 0W-20 is approved for use in Porsche vehicles that require a Porsche C20
specification 0W-20 lubricant.
I compared these specifications from the EC5 data sheet and the new LL IV FE data sheet:
Castrol EDGE Professional E C5 0W-20 (previously used for oil changes)
Density @ 15°C, Relative ASTM D4052 g/ml 0.8441
Viscosity, Kinematic 100°C ASTM D445 mm²/s 7.7
Viscosity, CCS -35°C ASTM D5293 mPa.s (cP) 5450
Viscosity, Kinematic 40°C ASTM D445 mm²/s 34
Viscosity Index ASTM D2270 None 203
Pour Point ASTM D97 °C -50
Flash Point, PMCC ASTM D93 °C 202
Ash, Sulphated ASTM D874 % wt 0.8
Castrol EDGE Profesional LL IV FE 0W-20 (Used by my dealer for the recent change)
Density @ 15C, Relative DIN 51757 g/ml 0.84
Viscosity, Kinematic 100C DIN 51562 mm²/s 8.0
Viscosity, CCS -35C (0W) DIN 51377 mPa.s (cP) 4100
Viscosity, Kinematic 40C DIN 51562 mm²/s 43
Viscosity Index DIN ISO 2909 None 165
Pour Point ASTM D97 °C -48
Flash Point, PMCC ASTM D93 °C 196
Ash, Sulphated ASTM D874 % wt 0.76
I don't really know how to interpret the specs as most of the LL IV FE 0W-20 specs are in DIN ratings. Can someone tell me if one formula is better than the other or if the differences are so miniscule that it doesn't matter ?
Thank you
