Synthetic vs Conventional Engine Oil
Synthetic engine oil is chemically engineered to form pure lubricants. All of its molecules serve a designed purpose – there are no contaminants. Their uniform molecular structures provide better friction-reduction, fuel efficiency, and extreme-temperature performance than conventional lubricants.
Conventional engine oil is a petroleum product, refined from crude oil. Crude oil is not pure. It comes out of the ground mixed with contaminants like sulfur, nitrogen, oxygen and also metallic contaminants like nickel or vanadium. The refining process removes most contaminants, but some remain. The non-oil components interfere with lubrication, and decrease engine performance.
Is Synthetic Oil Better?
Synthetic engine oil is more expensive up front, which is always a consideration, but for many vehicles and driving conditions, it provides superior performance.
Generally speaking, synthetic motor oil will nearly always last longer than conventional oil, saving you time and money. But your specific synthetic oil change interval will depend on several factors, including operating conditions, motor oil quality and personal preference.
Does Excalibur Auto Repair Use Synthetic Oil?
Yes. At Excalibur Auto Repair we use 100% synthetic engine oil (not a blend) for every vehicle we service.
