Buying Guide / Decision Criteria

Viscosity Ratings

Motor oil viscosity indicates how thick or thin the oil is, which affects its performance in both cold start and high temperature environments. For example, a 0W-20 rating means the oil flows easily at low temperatures, while the '20' represents its viscosity at high temperatures. Understanding the correct viscosity for your engine based on climate and driving conditions is crucial for optimal performance.

Synthetic vs. Conventional

Synthetic oils are engineered for superior performance and often provide better resistance to breakdown and oxidation. In contrast, conventional oils can be more cost-effective but may not perform as well under extreme conditions. We advise considering synthetic options for newer vehicles or those subjected to rigorous driving conditions.

Engine Type

Case-specific motor oils exist for various engines: high mileage, diesel, and racing oils carry specific additives that enhance performance for those respective needs. Identifying your engine type and its specific requirements will ensure you select the best oil for its longevity.

Brand Reputation

Well-regarded brands often invest in research and development, leading to more advanced formulations. Choosing established brands like Mobil 1, Valvoline, and Castrol can often pay off in terms of performance and reliability.

Price Considerations

While some may prioritize the lowest price, cheaper oils can lead to increased wear and tear if they aren't suited for your engine. We aim to find a balance between cost and quality, ensuring you get adequate value without compromising performance.
