FREQUENTLY ASKED QUESTIONS
Q: What's the difference between synthetic and cellulose media?
A: Synthetic media offers higher dirt-holding capacity (40% more than cellulose), better flow characteristics, and maintains efficiency throughout the service interval. Cellulose media tends to compact over time, reducing flow.
Q: Is this filter compatible with synthetic oils?
A: Yes, our LF551A is specifically engineered for use with both conventional and synthetic oils (including Group IV and V synthetics). The media and gasket materials are fully compatible with modern additives.
Q: What's your MOQ and lead time?
A: Minimum order quantity is 60 pieces. Standard lead time is 15-20 days for stocked items. We offer expedited production for urgent orders - contact us for details.
