meron sila libro ng catalogue at cross reference, pero bawat tanung ko panay walang stocks...puro pang heavy duty and pang large machines....

sa distributor ng parker racor at donaldson filters, ganun din wala sila stocks ng mga sizes that belongs to the car segment...
Correct. The focus of these stores is for fleet and heavy equipment customers. For these types of equipment, the filters are both more expensive and customers are more discriminating. Plus the filters are changed more frequently. It may surprise a lot of people as to how often the filters are changed. For example, for a Komatsu HD325-6 mining dump truck, the recommended replacement interval of the oil filter is 250 hours. If the truck runs 20 hours a day, the filter has to be changed every 13 days.
