Conversely, in high heat, conventional oil is prone to oxidation and thinning, which can lead to increased engine wear, whereas synthetic oil maintains its viscosity and protective qualities much longer under stress. For most vehicles, this is a sign that the engine was already deteriorating, not that the synthetic oil caused damage.
How Synthetic Oil Resists Engine Sludge Better Than Conventional Oil
This comparison breaks down the realities of each option to help you decide what is best for your specific situation. Feature Regular (Conventional) Oil Synthetic Oil Base Composition Refined crude oil Chemically engineered molecules Cold Weather Flow Thicker, slower to circulate Thinner, flows immediately Heat Resistance Breaks down faster Resists thermal breakdown Change Interval 3,000–5,000 miles 7,500–10,000+ miles Price per Quart Lower cost Higher cost Compatibility and Older Engines Some drivers worry that switching to synthetic oil in a high-mileage or older engine could cause issues.
Modern synthetic formulations are compatible with most engines built in the last few decades. Choosing the right lubricant for your engine is one of the most frequent decisions vehicle owners face at the repair shop.
How Synthetic Oil Resists Sludge and Protects Your Engine
In cold weather, conventional oil can become thick and sluggish, making it difficult for the engine to turn over and delaying lubrication on startup. Conventional oil typically requires changes every 3,000 to 5,000 miles, depending on driving conditions.
