Oils and fluids

It depends on your driving habits and vehicle. Full synthetic oils offer excellent protection against extreme temperatures, reduced sludge buildup, and even extended oil change intervals. If you frequently drive in harsh conditions, tow heavy loads, or own a high-performance vehicle, the extra cost is generally worth it. But for average daily driving, a good-quality synthetic blend may be enough, especially if you follow the manufacturer’s recommended service schedule.

While power steering fluid is a possibility, it could also be brake fluid or even A/C refrigerant oil. Brake fluid is usually clear or slightly amber and has a distinct odor. A/C refrigerant oil is often clear or slightly tinted and can be difficult to distinguish without specialized tools. Power steering fluid often has a slightly darker, amber hue. If unsure, you can always have a mechanic inspect the leak.

While some manufacturers claim their fluid is designed to last the life of the transmission, “lifetime” can be ambiguous. In reality, all fluids degrade over time. Many mechanics recommend changing “lifetime” transmission fluid at certain intervals, typically around 60,000 to 100,000 miles, especially under heavy use.
