Thanks. I will try to find "Mega Grey" instead of Mannol. But u r right, base point is that until & unless we put proper sized seal, that oil leakage will not stop
@sayedgulhassan
I have tested almost all "reputable" shops in my proximity 
@RehanBhatti
Bhatti sb., if possible, can u reopen your tikki & paste pictorial "steps of repairing". Whatever i am understanding since last 2 months by your writing, i have played all these tricks upto my understanding but result is Zero/Zero of mine
@harryberry15
No issue if u convert from 5w-30 to API SG 10W-40. But i will recommend to flush your engine with Liqui Moly products at this point to get rid of 5w-30 oil residue within components(As your car is decade old practiced with Light oil)
Use this product:

Bhatti Saheb, i have not used Zic X5000 API SJ so cannot give view or review over it. BTW @abid110 bhai kee baat bhee dekhye. Really it sounds like Diesel compliant
@abid110
I have recently read in another thread of pakwheels that for Cultus EDI, ZDDP requirement is also covered with SL grade??? If this is true then SL variant is available in Caltex & Castrol too
(Keep in mind Pak Suzuki is not marketing SL as requirement)
