Duron-XL and Duron-E-XL motor oils from PetroCanada provide significant benefits over standard oils including:
1. An extended oil drain interval of 15,000 km or more, reducing service visits from 4 to 1.
2. Double the life of oil filters, reducing replacement costs.
3. Protection of the engine from harm caused by CNG and prevention of carbon and varnish build-up.
4. A guaranteed 15-20% increase in vehicle fuel mileage, compensating for higher fuel costs.
