Having problems with your 1994 BMW 5 Series ?
Castrol GTX 20W-50
\015 Is this engine oil suitable for 1994 525i it says it Meets APL SL\\CF.\015\012Exceeds APL SL high temperature test\015
Basically those numbers mean it is 20 weight oil when it is cold and 50 weight when it is hot. it should be fine for that motor tho i would recommend 10w30. with the heavier oil you should find the motor quieter tho in extreme cold temperature it will be harder to turn over.
