Costcos Kirkland motor oil, produced by Warren, is also the manufacturer behind the oil for Amazon and Walmart's Supertech brand. It complies with the current API standards for motor oil. Generally, it performs comparably to most other synthetic oils unless your vehicle has specific requirements or is heavily modified.

You can safely use 5w-30 oil in vehicles designed for 5w20 or 0w20. The 20 weight oils are primarily aimed at meeting Corporate Average Fuel Economy (CAFE) standards rather than optimizing engine longevity. However, it's advisable not to use a 20 weight oil in a car originally designed for 30 weight oil.

A lot of vehicles use 6 quarts. My Toyota is 6.4 quarts. It is a lot easier to use 6 1 quart bottles than buying multiple 5 quart jugs.

It's a better deal for the in warehouse 2-5qt for $30

Quote from MellowHerring7508

If your car takes 3.7qt, how confident are you get to the right amount if you don't have any measuring cup or some sort? A 1qt bottle would come in handy imho

The graduated markings on the side of the 5 gal juge, and the engine dipstick. you don't need to dose in a boat load of small bottles to know you're getting the right amount.

will the leftover oil be good as much as the one in unopened box?

if I buy the one 2x5qt, it's cheaper.
however, the oil will start being exposed to air.
Is that ok?
