every oil claims that it is the best. you have to look in the manual or on the oil cap and use that grade of oil. i personally found that Valvoline is the best oil for my saturn it doesn't burn at all plus all oil has to meet a standard of quality and additives in the us so they are not all that different for standard oil not synthetic those oils should be twice as good.
