Oil Type and Change Intervals

Let’s zoom in on something super important: oil. Choosing the right oil and sticking to a good change interval is crucial for the health of your 2014 Toyota Tundra 4.6L V8 engine. Toyota typically recommends using a high-quality synthetic oil to provide the best protection and performance. The oil weight is usually 5W-30, but it's always a good idea to check your owner's manual for the specific recommendation for your vehicle. Using the correct oil weight is crucial because it ensures that the engine parts are adequately lubricated. As for change intervals, a general guideline is to change your oil every 5,000 to 7,500 miles. However, this can vary depending on your driving conditions. If you do a lot of stop-and-go driving, tow heavy loads, or drive in extreme temperatures, you might want to change it more frequently. Synthetic oils can generally go a bit longer between changes, but it's always better to err on the side of caution. Regular oil changes help remove contaminants and keep your engine clean. When you change your oil, it’s also important to replace the oil filter. The filter removes debris and contaminants that can damage your engine. Using the right oil and sticking to a regular change schedule is one of the best things you can do to keep your Tundra's engine running smoothly for years to come.
