bro, personally im all for 0w-20 n planning to twist their arm to pour 0w-20 n will be paying the difference of cost.
as i opted for extended warranty, which enables me 3 oil changes FOC, i take it as a blessing as after all this economic drama oil prices have gone bizzark..
so as an inflationary policy matter i will avoid spending any extra penny which can be saved n try to convince myself on 10w-40 n enjoy atlest 9 months or so of free maintenace time!
