Which Diesel Engine Oil...

[turk182]

based on the Diesel Engine Oil Specification Database thread in this forum, i have narrowed down my choices to these 2 oils:

Oil Name : Shell Helix Diesel Super
Blend : Mineral
Rating : API CF/SJ
Viscosity : 15W-40
Retail Price : P165.00 per liter
Recommended for what types of Diesel Ride: All including gasoline

Oil Name : Castrol CRD Plus
Blend : Mineral
Rating : API CF-4 (upgraded from previous CF)
Viscosity : 20W-40
Retail Price : P130.00
Recommended for what types of Diesel Ride: Pajero, Trooper, LC, etc...

I can't seem to find an oil which is both CF-4 and 15w40.... Which of these two is better suited for my '03 Patrol (ZD30DDTic)?

I'm planning to do my 1K PMS early next week...Thanks for all your help...
