What are the differences between race car oil, like the oil used in NASCAR, and the oil used in our everyday road cars? NASCAR oil regulations are fairly unrestricted, allowing for unique formulations, whereas road car oils need to meet very specific industry requirements for certifications.

In the video below, Jason Fenske with Engineering Explained, dives into the differences between engine design, drain intervals, oil viscosities, oil additives including zinc (ZDDP) and bespoke versus mass market formulas.

Synthetic vs. Conventional

Your engine needs protection that conventional motor oils can’t provide. Synthetic motor oils are the answer. And some synthetics are rewriting the limits of motor oil. With Mobil 1™ advanced full synthetic motor oils, you get outstanding performance, long-lasting protection and extended engine life.

Made differently: 3 reasons why synthetics win

Keeping your engine running strong depends on what you pour into it, so it’s important to know some motor oil basics. Synthetic motor oils, such as Mobil 1, outperform conventional motor oils because of how they’re made:

• 1. High-quality base oilsMobil 1 synthetic oils are developed from a proprietary blend of high-quality base oils. Conventional oils are made from a different blend of less refined base oils.
• 2. Hand-selected componentsMobil 1 synthetic oils include a system of more than 15 hand-selected components as a unique proprietary blend that helps the oils retain their protective qualities under extreme conditions. Conventional oils don’t include the same system of hand-selected components, so they break down quicker and provide less protection under extreme conditions.
• 3. Advanced technology and expertiseMobil 1 synthetic oils are specially formulated by a dedicated team of scientists and engineers. Up to 20,000 hours of lab/field testing and 500,000 miles of road/track testing go into each bottle of Mobil 1 motor oil.

Engine protection: A head-to-head comparison

The true measurement for motor oils is how well they can protect your engine from the demands of everyday use. By delivering unsurpassed wear protection, the next-generation technology of Mobil 1 synthetic oils can protect your engine better and keep your vehicle on the road longer than conventional oils (synthetic blends included).

Mobil 1 keeps your engine in excellent condition

A dedicated team of scientists and engineers maximize the synthetic capabilities of Mobil 1 motor oils by carefully selecting and combining components, achieving a fully balanced formulation that ensures outstanding engine performance and protection. That’s a big reason why Mobil 1 motor oils keep important engine parts in excellent condition for 250,000 miles.
