What's the 2003 BMW 330Ci oil type?

The 2003 BMW 330Ci uses SAE 5w-30 full synthetic oil. It has a capacity of 6.9 quarts. Oil keeps the internal parts of Your car's engine cool and lubricated and it also keeps the moving parts from grinding against each other thereby reducing wear and damage. The cost of an oil change for Your BMW is $200 for parts and labor. You should get an oil change every 15,000 to 20,000 miles. You will know that it is time for an oil change if You notice increased engine noise, shaking while idling, excess exhaust, an oil smell inside the vehicle, transmission shifting issues, and of course if You see the Check Engine or Oil Change lights come on.
