The original shop still hasn't responded to me as well. I feel like taking them to court, I'm pretty pissed that they're dodging me.

The guy is playing stupid now. Saying stuff like 5w40 is ok for both 229.5 and 229.51. I have no idea what motoring ombudsman is 
.
I left him an angry message at his voice machine. I have a feeling he's just gonna play stupid.
edit: I called him again, and he actually picked up. I went on a rage tear. He told me that the oil companies keep saying that it is ok, he is taking more of an apologetic tone now. He says if I can get the oil companies to admit that they're at fault, he'll give me my money back + some money for my time.
Sigh.... It's so sad that a group of Mercedes Benz enthusiasts on a web forum is 10x more knowledgeable than so called professionals. Thanks guys for the continued help.

I've sent an email to both CoastalBP and Valvoline with information I've gathered from this thread and other websites. If they admit that they're wrong in this, I should finally win this stupid ordeal. The shop promised me to pay for my time, so who knows, maybe I'll end up happy at the end.

YES! VICTORY IS NEAR. CoastalBP have replied to me apologizing for the misinformation and the misunderstanding. They have told me to use that email as proof to get my money back. Valvoline is playing very quiet right now, I will keep harassing them until they talk to me 
I love this forum and I love you all, that's all.
Peace out!

There is one big failing in technical people today. The inability to say "I don't know the answer to that. I will find out & come back to you"!
Nobody in this world can possibly know everything. The best they can do is learn something new every day. This requires an enquiring mind.

If there's one thing I learned from this fiasco is that professionals don't always know what they're talking about, I should always do my own research.
Oh, so its a way to file complaints. I hope to never use it, but it's nice to know the option is there.
The guy called today, profusely apologizing for the entire mess. I told him I understand that the oil company gave him wrong info. He has told me he will refund my cheque, but no mention of cheque for my time (he mentioned this earlier). He instead told me he will give me free oil changes 3-4 times. I mentioned that he told me about the cheque, and then he told me I can ask for what I think is reasonable for my time. Unfortunately, I couldn't bring myself to say the amount. I told him any amount would do. Let's see how much he thinks my time is worth hahahaha.

the quick-lube shop put in 5W40 229.51 oil for MB diesels, and water temp went up and milage went down, correct?
1) what were the oils before and after the 5W40 noted?
2) what used oil did you save a bit of ?
The oil analysis shops in the US are like this one:

You pay extra for a TBN test.

That is, what oil was in before the put the diesel oil in, and the oil after the diesel oil was removed.
Also any updates on water temp?

Coolant temp. my bad.
I've never watched the show, so I can't say I understand what point you're trying to make here. You wanna clarify? The shop I went to say they used a 229.5 approved Motul Oil. I brought them a sheet of approved oils and they said they use Motul X-cess which is on the list.
Edit: I thought the coolant temp went from 80-100, but apparently 90 is the correct operating temperature so I must've been mistaken. I could swear it used to sit right at 80, maybe I never drove it long enough to reach 90 since I haven't had the car very long. I didn't actually get the car until July and didn't really drive it anywhere except to work and back. The coolant temperature went higher than normal and I had a steep consumption swing after the oil change so I decided to look into the oil. But I've been told over and over that the oil shouldn't have that kind of effect, so any guess is as good as mine.

Price for service "A" is significantly less in Southern California where there are a lot of dealers that compete with each other. I have paid as little as $110 and never more than $150 for Service "A" for my CL550 at a dealer including a free loan car. Usually they use Mobil One. Most dealers in the area will match the price of their competitor dealers.

I changed my oil at an oil change franchise (decided to avoid MB since they were charging 180). I checked the approved engine oil sheet and found out that Volvoline synpower was on the approved list for my engine (M272). So I went to this shop that was offering it for a great price, only to find out that they no longer offered it. Then they told me to use an engine oil called Advant by Irving, and that it's approved for MB as well as other premium European cars. I wasn't so sure at first, but they were pretty adamant about it being great and that their computer showed it matches with my car.... now my mileage has gone down the gutter. Went from like 12.4 l/km to like 15-16l/km. Any thoughts on why this would be?
The oil code for that engine is 229.51. I found out that the oil required for my car is 229.5. But then after some research, apparently 229.51 used to be on the approved list for Petro cars until the U.S. started adding ethanol to their cars, and the only reason why 229.51 isn't accepted is because of the ethanol causing some kind of blockage?
The premium gas in the gas station I go to says there is 0 ethanol in it's premium gas.
Should I get the oil changed?

I've had my M276 e klasse for 8 years and this is the only product I use. Aside from this product I also use this one at every service:
https://products.liqui-moly.com/additives/cera-tec.html
Finally, I add this to my fuel tank every 6 months:

FCP Euro is a well respected service centre in the US and together with my MB specialist, I got this idea from them:
Hope this helps. Good luck!
