Engine oil is one of the most critical fluids in your vehicle, yet it is also one of the most misunderstood. Choosing the wrong grade or leaving it too long between changes can cause significant engine wear. At Brookes Auto Repair, we are committed to helping our customers make informed decisions about their vehicle maintenance.
What Does Engine Oil Do?
Engine oil lubricates the moving components within your engine, reducing friction and preventing metal-to-metal contact. It also helps to cool the engine, suspend contaminants for removal by the oil filter, and protect against corrosion.
Understanding Oil Grades
Oil viscosity is described using a two-number code such as 5W-30 or 10W-40. The first number (followed by W for winter) indicates how the oil flows at cold temperatures — a lower number means better cold-start protection. The second number indicates viscosity at operating temperature. Your vehicle manufacturer specifies the correct grade for your engine; using the wrong grade can compromise lubrication and increase wear.
How Often Should You Change Your Oil?
Modern vehicles with synthetic oil typically require changes every 10,000 to 15,000 miles or annually, whichever comes first. Older vehicles or those using mineral oil may require more frequent changes. Always follow your vehicle manufacturer’s recommendations.
Warning Signs of Oil Problems
Low oil pressure warning lights, dark or gritty oil on the dipstick, excessive smoke from the exhaust, or unusual engine noise can all indicate oil-related issues. Do not ignore these signals — contact Brookes Auto Repair promptly for an inspection.
