Buy your self a big drain pan or a top sider pump and DIY. save 40-50%, only takes a few minutes. Just use a Mercedes spec oil, like Mobil 1 (0W40). Check the internet for bargins on the oil. I bought it for $4.99/qt., you will need to buy at least 8 qts., don't over fill. Look on the forum for how to do it, getting the top "O" ring in the correct place is critical. If you pay attention, you will be able to see exactly how to do it. Take a pic of each step, so you can see where each "O" ring goes, make sure filter element is seated down all the way. Tighten filter cap carefully, donot over tighten. Easy to do. I'm sure if a member lives close to you they would help you do it the first time like they did for me.
