Brother Gul, many thanks for your prompt participation. Here are two pence from my side regarding engine oils & lubricants. I have experienced following oils useful: -
1. LIQUI MOLY (LM) - (German) - Available from LM authorized distributors in I-8, Isloo
2. Mobil - (USA) - Available from Mobil authorized dealers in I-10, Isloo
3. Havoline - Now a well established and well reputed brand in Pakistan
4. ZIC - Another good name
5. Remaining oils & lube brands in Pakistan
Each oil has different grades to be used according to weather as well as engine condition. Newer engines will need thinner oil where as older engines are better treated with thicker oils. Hotter weathers require higher SAE numbers (as those are thicker.) And vice versa for colder weathers.
Kind regards
M
