ZIC oil price estimates dito sa probinsya:

ZIC SD5000 15w-40 multi-grade Php 175/liter
ZIC UP 10w-40 semi-synthetic Php 210/liter
ZIC XQ 5w-40 fully synthetic Php 550/liter

Konti lang ang price difference ng multi-grade at semi-synthetic nila kaya ok lang mag-semi-synthetic. Pero sa performance ang layo. Sa multi-grade medyo rough na ang engine response at around 4,000kms pero sa semi-synthetic smooth pa rin sa 4,500kms. Observed this on my 2010 strada 4x2 with OEM oil filer and OEM air filter.
