Liqui Moly Rs 700/ litre hai.
A pakwheeler from Lahore @automotorsport_lover told about this official retailer of Liqui Moly in Lahore.
LIQUI MOLY - MUSLIM TOWN MORR, Mr. Afzal Tahir : 0300-4134599
20W-50 is perfectly fine for new engine. As compared to 10W-40, it makes engine more silent and gives smoother overall feel.
SGO loses viscosity sooner but overall it gives better feel to engine than Zic and AX5.
Well if total 20W-40 is working great for you then why not try it in GS also??? SGO is also provided to Suzuki by Total.
As you said that you are touchy about GS, then must try Liqui Moly. Don't worry about it being 20W-50. After trying many thinner grade oils, now i have Havoline 20W-50 in my GS (if it makes you feel any bettter ).
