I am using 10W-30 Havoline formula right now .Its good however its only API SL while latest oil grade is API SN(two grades superior than Havoline formula) .But as you said manual recommends 5W-30 for Vitz 2006.....That means I need to change!!!!
What is the best 5W-30 oil choice as neither Havoline nor Shell has this "5W" grade oil with 30 viscoity?
ZIC ,Mobil and rest are too risky because of:
1). Their fakes in the market(which 'might' be avoided by buying them from the authorized distributor and 'hoping' its the original one)
2). Original ones with ever degrading quality by distributors in Pakistan(which cannot be avoided)
