Synthetic vs. Conventional Oil: Which is Better?

Deciding between synthetic and conventional oil for your 2012 Nissan Altima 3.5 SR can be a bit of a head-scratcher, but let's break it down. Conventional oil, also known as mineral oil, is derived directly from crude oil. It's the more affordable option and has been used in engines for decades. However, conventional oil tends to break down more quickly under high temperatures and doesn't offer the same level of protection as synthetic oil. This means you'll need to change it more frequently, typically every 3,000 to 5,000 miles. On the other hand, synthetic oil is engineered in a lab to provide superior performance and protection. It's more resistant to thermal breakdown, meaning it can withstand higher temperatures without losing its viscosity or lubricating properties. Synthetic oil also contains fewer impurities than conventional oil, which helps to keep your engine cleaner and reduce sludge buildup. Because of its enhanced properties, synthetic oil can often extend your oil change intervals to 7,500 miles or more, depending on the specific oil and your driving conditions. While synthetic oil is more expensive upfront, the extended oil change intervals and improved engine protection can make it a worthwhile investment in the long run. Many drivers of the 2012 Nissan Altima 3.5 SR choose synthetic or synthetic blend oils for the added peace of mind and performance benefits. Synthetic blends offer a compromise between the two, combining synthetic and conventional oils to provide some of the benefits of synthetic oil at a lower cost. Ultimately, the best choice for your vehicle depends on your budget, driving habits, and how long you plan to keep the car. If you're looking for the best possible protection and performance, synthetic oil is the way to go. If you're on a tighter budget and don't mind changing your oil more frequently, conventional oil can still be a viable option. Just make sure to stick to the recommended oil change intervals and use a high-quality oil that meets Nissan's specifications. Always remember to check your owner's manual for the manufacturer's recommendations, as they know best what your car needs. Regardless of which type you choose, regular oil changes are crucial for maintaining your engine's health and longevity. So, keep that oil fresh, and your Altima will thank you!
