The best synthetic oil for your car starts with the specifications set by your vehicle manufacturer. Your engine is designed to use oil with a specific viscosity and performance standard, and using the correct one helps protect your engine and maintain performance.
Mileage, engine condition and how you drive can also help determine which synthetic oil option is best for your vehicle.
What the Numbers on Motor Oil Mean
Numbers such as 0W-20 or 5W-30 describe the oil’s viscosity, or how easily it flows at different temperatures. Your vehicle manufacturer specifies the viscosity your engine was designed to use.
Choosing the correct viscosity matters because your engine depends on oil flowing properly to lubricate and protect its internal components.
Does a High-Mileage Car Need Different Oil?
It may. High-mileage synthetic oils are formulated specifically for older engines and may contain additives designed to help condition seals, reduce oil consumption and provide additional protection against wear.
But reaching a certain mileage doesn’t automatically mean you should switch. The condition of your engine and manufacturer specifications should also be considered.
How Florida Heat Affects Which Oil You Should Choose
Florida’s heat makes proper engine lubrication especially important, but you shouldn’t choose a thicker oil simply because you live in a hot climate.
Use the viscosity and oil specifications recommended for your vehicle unless a qualified technician or the vehicle manufacturer recommends otherwise.
What Florida Drivers Should Consider When Choosing Motor Oil
Engines are designed with specific oil requirements, and two cars sitting in the same driveway may need completely different products. Start with the manufacturer’s specifications, then consider the vehicle’s mileage, condition and how it’s driven.
Expert Tip: “Synthetic oil brands are very similar. Some brands, like Mobil 1, Royal Purple, and Amsoil, do make synthetic oils that are made to handle extreme conditions. But without extreme conditions Quartz and Shell oil are the preferred brands because they constantly update their oils to keep up with all manufacturer specifications and requirements.”
