Frequently Asked Questions (FAQ)
Q: Is a more expensive oil always better?
A: For a modern engine, a full synthetic oil is almost always necessary to meet manufacturer specifications. Within the full synthetic category, paying more often gets you more robust additive packages, higher-quality base oils, and specific OEM approvals that may be crucial for your car's warranty and longevity. However, the most expensive oil on the shelf is not automatically the best for your specific vehicle if it doesn't match the required specifications.
Q: Can I switch between different brands of synthetic oil?
A: Yes, you can safely switch between brands of full synthetic oil, provided the new oil meets or exceeds the viscosity grade and specifications required by your vehicle's manufacturer. There is no need for a special flush. The different additive packages are compatible.
Q: How often should I really change my oil if I use a top-tier synthetic?
A: Always follow the service intervals in your owner's manual, which are based on the oil's performance capability. Many modern cars with top-tier synthetics have extended service intervals (e.g., 10,000 miles or more). Do not exceed the mileage or time interval specified by your vehicle's manufacturer, even if the oil bottle claims a longer life. Your engine's operating conditions (severe duty: towing, extreme heat/cold, frequent short trips) may necessitate more frequent changes.
Q: What does "Low-SAPS" or "Mid-SAPS" mean and why is it important?
A: SAPS stands for Sulfated Ash, Phosphorus, and Sulfur. These are elements in some additive packages. Low-SAPS oils have minimal amounts, making them safe for modern exhaust systems with Gasoline Particulate Filters (GPF) or Diesel Particulate Filters (DPF), as ash can clog these expensive components. Mid-SAPS oils offer a balance. Always use the oil type specified for your vehicle.
Q: Does engine oil "wear out" or just get dirty?
A: Both. Over time, the additive package depletes as it performs its functions (neutralizing acids, preventing wear, dispersing soot). The base oil also oxidizes and breaks down due to heat and mechanical shear. Contaminants like fuel dilution, moisture, and combustion by-products accumulate. This combination reduces the oil's ability to protect, necessitating a change.
Investing in one of the world's best engine oils is a direct investment in the health and longevity of your vehicle. By matching the oil's technical capabilities to your engine's precise requirements, you ensure optimal performance, maximum fuel efficiency, and protection against costly repairs for years to come.
