Essential FAQs About Automotive Lubricants

Understanding vehicle maintenance includes knowing how often to change oil, the importance of lubrication, and ways to save on service costs through coupons like oil change discounts. Here are some common questions addressed about motor oils, oil replacement, and savings offers:

Why is regular oil change vital in aging vehicles?
Changing the oil removes dirt, metal particles, and other contaminants accumulated over time, replacing it with fresh lubricant to ensure optimal engine performance and longevity.

What do the numbers on motor oil bottles mean?
The first number indicates the oil’s flow at low temperatures, reflecting its viscosity during startup, while the second relates to high-temperature viscosity, important for engine protection at operating temperatures. Choose the right viscosity based on your vehicle's specifications.

Are chemical flushes necessary, and what do they do?
Chemical flushes maintain the cooling system's pH balance and remove oxidation from transmission components, ensuring smooth operation. Proper lubricants are essential for protecting vital engine parts and maintaining overall vehicle health.

What does it mean if engine oil appears milky brown?
This indicates coolant contamination, possibly due to a failed gasket or transmission cooler, requiring prompt professional inspection.

What is synthetic engine oil?
Synthetic oils perform better in extreme temperatures and are ideal for high-performance, turbocharged, or supercharged engines. They are more costly but offer longer-lasting protection and improved fuel efficiency, reducing the need for frequent changes.
