if it,s a brand new car, you better use what it calls for, incase it voids the warranty.What is the best motor oil i can use for a new car?
whatever your manufacturer recommends! most manufacturers use at least semi-synth oils, I wouldn't start using the top line full synth oils till after the first 20k miles , So the engine has time for everything to wear in before you increase the lubricity inside engine. Do not let some oil change place put 10/30 conventional oil in a new car most call for at least semi-synth 5/30, the extra viscosity can cause slow damage to engine when the engine is designed to use thinner oil. Its like pumping syrup thru something made to pump water. This is also why using Lucas products is a bad idea, all they do is increase viscosity and capture air lowering actual heat transfer and lube provided by oil.
use a synthetic motor oil probably castrol make sure to change it every 2800 miles make sure you use the right type for your car do not mix and match stick to an oil, they all have diffrent cviscosity and can wear cylinder walls.
I'll make an educated guess here and assume you're asking which weight to use, because the easy answer would have been Mobil 1 synthetic.





5W30 is as thin as I would recommend for a daily driven car, unless you live in Maine or Alaska. Thinner is better if you want a slight power advantage, but too thin and the oil's not protecting your motor anymore. And since cold-weather is right around the corner, definitely use the thinner stuff. Just know that you're taking a slight risk using lower weights on a brand new car, but if you're street racing, clearly you're not squeamish about being a little rough.





And absolutely use synthetic over conventional. Conventional is biological in nature, and like produce, will degrade over time into worthless sludge. Synthetic is engineered, and yes as an oil-product, it too is inherently biological, but it's been so thoroughly processed the shelf-life stability is far superior. Think of it this way. The old rule of thumb for oil changes is 3 months or 3000 miles, whichever comes first. This come from the old-school when there were no synthetic oils. For synthetics, the rule is 3000 miles. There's no time limit.





And don't pay big money for high endurance 10,000 mile oils. While the oil may survive, the oil becomes saturated with little metal bits and burned oil that naturally accumulate over time. You don't want that junk swirling around in there for 10,000 miles. That makes as much sense as a 3-day baby-diaper. Frequent oil changes are the only way to keep your motor happy.
