Factors to Consider When Buying 5W-20 Engine Oil

Brand Standards: Choose oils that meet API SP and ILSAC GF-6A standards. These oils work with modern engines and catalytic systems. They also work well with ethanol fuels.

Engine Cleaning: Good oils keep your engine clean and remove deposits. They prevent sludge buildup that can damage your engine. Clean engines run better and last longer.
