Conventional oil is refined from crude oil and works well for many vehicles, but it breaks down faster and needs changing every 3,000-5,000 miles. Synthetic oil is lab-engineered to perform longer and better, lasting 7,500-10,000 miles or more between changes. Synthetic also handles extreme temperatures better, improves fuel economy, and reduces engine wear. The trade-off is cost-synthetic is pricier upfront but saves money over time and offers extra protection. Your vehicle's owner's manual specifies which type your engine needs. Many modern Volkswagen models benefit from synthetic oil's superior performance. Our Service team at Castle Volkswagen of Downers Grove can recommend the best choice for your specific vehicle and help you stay on schedule. Call (630) 598-9986 to discuss which oil is right for you.
