Im going for an oil change of my Jeep in the morning so need urgent professional help
 

Iv been using:
Caltex Havoline CNG (with green cap) costing Rs1000 for 3 Litre
Leppon oil filter costing Rs150 and i change them both at 5000kms.

Now iv bought:
Arrow oil filter (Wix dealer) (Hope its better n didnt get ripped off did i?)

1. Which oil to go for under Rs 1500 price tag?
2. And which oil filter (If the Arrow one i bought is not good) ?
3. How often to change both?:dunno:

Thx
