What kind of oil does the 2018 Mercedes C300 need?


The oil needed is 0W-40 or 5W-40. These two weights were mentioned in the owner’s manual.
 

What is the oil change interval for the C class?


For the 2018 sedan or coupe with a 2.0 engine, the interval if you use conventional oil is around 3,000 to 5,000 miles. If you use synthetic oil then the interval is up to 7,500 to 10,000 miles. Oddly, this is not mentioned in the manual, but we searched two authorized Mercedes dealerships in two different states and both sites confirm the mileage mentioned here, one dealership in Tampa and another in Dallas.
 

How often should I check the oil using the dipstick?


According to Mercedes, this vehicle can consume up to almost 1 quart (0.9 to be exact) for every 600 miles depending on if you drive at high speed or if the vehicle is new. It all depends on various factors so please check the oil level a few times a month.
 

What is the oil capacity for a 2018 C300? How many quarts do I  need?


You will need 6.9 quarts with a compatible oil filter. A good idea is to buy 8 quarts to keep an extra quart handy in case your engine consumes oil. This is stated in the manual and is part of a compression engine. It does not mean the engine has a leak, although you should always check for leaks if you feel the engine is losing too much oil or more oil than the manual mentions.

Oil changes for my vehicle are expensive, what can I do to save money instead of going to the dealership?


Buy your own top synthetic and take it to a local mechanic in your area. Have the mechanic order a filter for your Mercedes before going to save even more time. This will come out way less expensive than going to the dealer. You can buy our European formula below.
