Procedure

  1. Jack up the vehicle and secure it with jack stands

  2. Remove engine splash shield. It is held in place with eight 10mm bolts. Some models use 8mm screws or plastic retainers.how to change engine oil on MAMO Watch the following video on how to remove an engine undercover (under shield).

  3. Locate the oil drain plug. Here is a close up picture of the oil drain plug on this Mercedes-Benz. Some models have the bolts in the middle of the pan towards the rear. Remove the 13mm oil drain bolt. diy oil change MAMO instructions step by step guide oil drian plug

  4. Carefully remove the oil drain plug. drain oil Mercedes-Benz diy

  5. Allow the old oil to drain for at least ten minutes or until there is no more oil dripping from the oil pan

  6. Replace the drain plug washer.  
  7. If you install the drain plug without a washer, it will leak oil. Reinstall the oil drain plug.  0
  8. Reinstall the drain plug and torque it to specification. 
  9. Locate the oil filer on top of the engine of your Mercedes-Benz. Use a filter wrench to remove the oil filter. location of engine oil filter on M112 M113 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 diy oil change

  10. Remove the old oil filter. Install the new filter on your M112 M113 and tighten it by hand—lastly, torque to 25Nm.

  13. Add oil as necessary to bring the level between the MIN and MAX marks on the dipstick. Don't fill the engine with oil above the maximum mark on the dipstick. 
  14. If your Mercedes-Benz doesn't have a dipstick, you will need to check the oil level via the instrument cluster. check engine oil do not overfill

If your Mercedes-Benz does not have an oil dipstick, check the oil level via the instrument cluster using the steering wheel buttons. 

An alternative method that is faster and doesn't require raising the vehicle is to use an oil extraction pump. With an oil extraction pump, you can remove the oil via the oil dipstick tube.

Oil Capacity

  1. V8 models, including 430 and 500, require 8-8.5 liter (quart). V6 models, including 240 and 320, require 7-7.5 liter(quart).
  2. Make sure you install a quality filter. A fleece filter is recommended. Cheap oil filters degrade quickly and are not able to filter debris for 10,000 miles.

Applications

The M112 is one of the most common engines used on almost all Mercedes-Benz classes from 1997-2007 that end with 240 or 320. For example C240, C320, E320, CLK320, ML320 etc.

The M113 engine is a V8. Models that have this engine end with 430 or 500. For example E430, E500, ML500, R500, G500 etc. This engine is installed on E, C, CLK, SL, CL, R, ML, GL, G classes.

The instructions are the same for both engines, with one exception. The oil capacity for the V8 and V6 engines is different. Check oil capacities in the next section. A complete list of applications is found at the end of the tutorial.

I would remove anything but the Genuine Mercedes and the Mann oil filter from the list. The Fram and the Mobil 1 are not made of the fleece material, and I do believe they are both paper material, and will not last the 10,000 mile internals.
I agree that the filter needs to be a high mileage filter. If you are going to go for 10k mile intervals, make sure to use a filter that is desiged for long intervals. I see it many times where cheap filters are used and the oil is changed every 10k miles or even longer. The filter starts to crumble and doesn't do its job past 5k miles. Then oil sludge starts. Then blaming MB is next.
Forget about jacking the car up and removing the drain plug. Since there is an dip stick tube located on these engines, invest in a good oil extractor pump. The one I purchased three years ago is still going strong and will save you LOTS of time and belly crawling. I have a 2005 C240 that takes 20 minutes from start to finish for the oil change. Heck, it can take just twenty minutes or more to get the car up on ramps and remove all the screws holding the splash guards in place.

Warnings


  • Prolonged and repeated contact with mineral oil can result in dryness, irritation, and dermatitis.
  • Used engine oil contains potentially harmful contaminants which may cause skin cancer.
  • Wash your skin thoroughly with soap and water to remove any used engine oil. 

Frequently Asked Questions


What type of engine oil do I need?

The oil viscosity is usually printed on the oil cap. If it is not, then you need to find the owner's manual under the recommended fluids and lubricants section typically at the end of the owner's manual. 

  • at the oil cap
  • owner's manual
  • sticker by the top radiator support

Should I change the oil when the engine is hot or cold?

  • There is a lot of discussion on this topic of whether you should change the oil when the engine is hot or cold. Ideally, the oil should be slightly warm so it can flow easily but not burn you. 

How much does it cost to change the oil?

  • Anywhere from $19.99 to $150. A four-cylinder engine that takes 5w30 or 0w20, such as a Honda Civic or Ford Focus, will only cost you about $20. A Mercedes-Benz E-Class that takes 8.5L synthetic oil and fleece oil filter may cost as much as $150 at the dealer. Two of the main factors that play a role in engine oil cost are the oil type (synthetic, synthetic blend, conventional) and oil quantity required. Oil filter quality and how easy it is to remove may also play a role in the price of an oil change.

How often should I change engine oil?

Typical recommended intervals for most vehicles. 

  • Conventional Oil - Every 3,000 miles
  • Synthetic Blend - Every 5,000 miles
  • Synthetic Oil - Every 7500-10,000 miles (verify owner's manual)

Follow the recommended manufacturer intervals.

Can I change the engine oil at home?

  • Yes, you can. Follow this guide. We hope that once you go over all the steps, you will feel confident about the procedure to change the engine oil at home.

Can I change engine oil once a year?

  • While the age of oil can play a factor in the engine oil life, you need to pay closer attention to the miles driven. If you drive very little (under 5,000 miles) and use synthetic oil, you should be ok with changing the oil once a year.

Can I change engine oil but not filter?

  • Not recommended. You should change the oil filter at the same time that you change the engine oil. Oil filters do not last forever, and if not changed regularly, they will not filter the oil or, even worse, clog. In which case, the oil may bypass the oil filter altogether, which is a situation you don't want as you may shorten the life of the engine.

Is it necessary to change engine oil every year?

  • Yes. Most drivers should change the engine oil at least twice if not more per year, depending on the oil type and miles driven. If you put about 15,000 miles per year which is the national average in the US, you should change the engine oil at least twice per year. Assuming that you are using synthetic oil and a good oil filter. 

Should I change the engine oil before or after storing the car for long periods?

  • Change the engine oil if stored for over 6 months. Oil can lose its lubricating properties when sitting for an extended period of time. Change the engine oil if your car has been sitting for a long time.

What happens if I don't change the oil?

  • You are shortening the life of your car. Sludge may build up. The engine may start to knock. Most importantly, bearings will wear much faster. You may not notice any symptoms right away, but you are causing premature wear to your car engine.

How much oil do I need to add?

  • Check on your owner's manual. Every car has a different capacity. There is no correlation between the number of cylinders and oil capacity. Some 6 cylinder engines require only four quarts, while others may require eight quarts. Always check the owner's manual. You don't want to overfill or underfill.
