Premium Conventional Oil – standard new-car oil (5W-20 or 5W-30 oil with 10W-30 oil as an option for high-temperature areas such as the desert in summer).
Full Synthetic Oil – made for high-tech engines where the oil needs to flow better at low temperatures and be at it’s top lubricity even at high temperatures. This oil type also costs more and some engines have features that synthetic oil doesn’t have.
Synthetic Blend Oil – synthetic/organic mix formulated for heavier loads and high temperatures. Popular blend for trucks/SUVs.
Higher Mileage Oil – formulated for vehicles with 75,000 miles or more. This oil type has an added seal conditioner that swells to stop leaks in the crankshaft. Always refer to your vehicle owner’s manual for the car manufacturers recommendation. Keep in mind, however, that the recommendation given is for a brand-new car, not the one that you put over 70k miles on since it was purchased. You can change oil brands when changing your oil but keep in mind to always go with a better type of oil, such as going from a premium conventional oil to the full synthetic oil.
