grid, ilan beses ko na sinabi na hindi nga magkasya sa sig yung extra info. our 5w40 isn't advertised naman and only a couple of shops carry it. we don't even have it on display and nilalabas ko lang when may gagamit. if you have such a huge problem with my sig then don't use the oil. geez... it's not that difficult naman and you're making way to big a deal out of it.

dyerms, thanks

guys, due to increasing prices for crude oil and basic commodities, Royal Purple oil will be having a price increase starting August 1. the oil will go from 440/qt to 500/qt.

if you'd like to avail of the 2100 promo this will be valid until July 31 nalang. After that the price will increase accordingly.

thanks!
