Oil change - every 6 months?




We just bought a 2018 W222 M276 E350 4Matic with 32k miles and every possible option on it. The single prior owner took extremely good care of this car. I had it inspected and it was pronounced perfect save for needing brake pads and tires soonish, which I’m doing.
So this car we bought because I recently discovered I have Stage III cancer so we will be driving five hours to MD Anderson
Will someone who clearly knows WAY MORE THAN ME tell me what to do please? I want to do the oil changes myself while I also teach my older boys (23&19) how to do the same. I’d like to buy it all from FCPEuro because of their return policy on WIPERS. Remember this has every option including the Magic… view? Those $180 wipers. 😉
How often?
Which oil kit?
Anything else I might need?
I think I might like to get some ramps - would that be easier/safer than jack and stands? If so does anyone have recommendations?
I know from reading that fresh fluids keep these engines running happy, and I want this engine to do that as much as possible while teaching the boys how to properly take care of things. So I’d like to buy the best I can get knowing I need as few issues as possible, because we have bigger issues.
I did check but there are so many options, and it’s hard to think clearly when you have a chemo ball pump connected to the port in your chest pumping 5FU literal poison into your jugular. Cancer sucks. Get your colonoscopy… you know the one you have been putting off. That’s WAY better than this. Anyway, sorry so long. Any advice is very welcome as appreciated!

Is LiquiMoly just for a leaky engine or is it better than say Mobile 1? Is the Mercedes oil relabeled Mobile 1? I’ve read the Costco synthetic is exactly the same as Mobile 1.
Feels like info overload. I haven’t worked on cars for 30 years and then not too much unless I had to and that was limited to a 280Z.




He demystifies oils/additives/misconceptions.
(Spoiler - there is no magic oil. Proper viscosity/specs/intervals are what you want - confirmed via testing). Because the 450 is turbo ‘d and direct injected, you’ll want to stay with an API SP oil, lower in Calcuum.

And I say yes to ramps; that's the easiest way to do oil changes. However, you might want to consider some "quick jacks" or similar low rise garage lifts and you can do a lot more than oil changes if you like.




Unfortunately EV cars will be the norm before engineers perfect the ICE. Until then Engine oils will get contaminated, collect in undesirable ways on different parts in different passages
as human hands and minds have inconsistent quality control. That and regional conditions, different drivers etc etc.
All you can do is use the factory guidelines as a minimum, common sense and hope you didn’t get Friday’s motor built by a person that couldn’t care less.
Can I get an amen?

I guess our fathers found us just as weird, but for different oddities....

I then buy it on Amazon. I have their 5w-30 ready for a spring oil change, and I change it yearly or somewhat close.
Get the filters and drain plugs from FCPeuro.
I purchased my car at 30k miles 4 years ago. 2 months after I purchased it, I noticed a strong burning oil smell. Took it to local MB dealer and it turned out it had a valve cover leak that was dripping onto the exhaust and also a right cam magnet & cover leak that was repaired under my after-market warranty. Fast forward to this week and I notice the same kind of smell on the engine that now has 51k miles. It turns out it has the exact same leaks from the same places along one more cam magnet leaking. The trans pan also appears to be seeping. So now it's in at my local mechanic to have 40+ hours of work done to repair the leaks. Fortunately the car is still under warranty for another 3 years through Endurance, who my mechanic has lots of experience with and knows how to negotiate with them.
Now I've consistently been putting on 5k miles per year with 1 annual oil change, with the majority of those miles during the warmer months. I'm in the Chicago area where we can have some pretty extreme temperature swings. Most of my mileage is local driving with occasional highway jaunts. I thought that at just 5k miles per year, the once a year oil change would be more than sufficient. What I learned from my mechanic is that with shorter trips and major temperature swings, gas will tend to mix with the oil (all cars do this through blow-by past the rings), but with lots of local driving the gas is remaining in the oil & not burning off, which causes the gaskets to wear out much sooner, especially in areas where gassed up oil is just sitting against the gaskets while the car is parked. MB doesn't use traditional gaskets for valve covers and cam covers, instead opting for a paste seal, which is more prone to failure with the described conditions. So even though I don't put many miles on my car, he said I should be changing the oil every 6 months, especially with the major temp swings and the car sitting more in the winter to avoid this situation from returning. He also mentioned that the 1 yr/ 10k oil change intervals are horrible for the car, especially as you get past the original warranty period where things start to fail. It's also the time where 2nd owners buy these cars and why they can be so expensive to maintain. More frequent oil changes seems to be the fix for many of the issues these cars experience.
Mechanics don't make money off oil changes so thats not what drives that. In fact he'd be better off if he had to keep doing all your repairs...
Oil changes are cheap. Mercedes charged me $180 to change the oil. Whats the big deal about spending $180 halfway between the MB recommended service intervals? I can't even get out of a restaurant for less than $180.

Now here’s a question. Why should I NOT use Liqui Moly? I see that a lot. Here’s a video about it from FCPEuro:
Everyone seems to love this stuff, but is it worth it, or only for older cars or if you are having leaks?
