Coolant ever 25k kms? Diff fluid every 30? Nah. Just follow the manual.

I'm cutting intervals short just for the fact it's the first flushes and cycles as per my ownership of the car, it's had 3 previous owners and from what I've inspected they haven't maintained the car nearly as well as I would have.
I've redone the full front suspension and I will start soon on the rear suspension. Most likely only going for the parts that are really needed and what's able to be done later on I won't rush but will keep my eyes on the wear.
I intend to do ignition coils and spark plugs within another 10,000 - 15,000KM tops as well.
You can never be too sure of what the previews owners did and I feel like making sure everything is flushed and fresh with new oils and fluids is key to keep a 2009 Benz running like new.

@c_benz300 love the enthusiasm. Never hurts to keep fresh fluids in the car.

i switched to 5w-40 molygen from liquimoly for my engine oil.
I buy all my stuff from FCPEuro, Amazon, AutohausAZ.
I like the MB oil filter over the MANN one that came in my last oil change kit from FCP. But that just my own personal preference. I felt it went on and off the oil filter stem easier.

for the rear suspension, you should check if your subframe is rusting/rotting out. Not sure if you live in a climate that inhibits that. I had my subframe replaced under the extended warranty at my local MB dealership. They replaced the entire subframe and I had them install new struts, coil springs, all the rear control arms, rear sway bar, lower control arm bushings get replaced as well. Definitely something to check and look into!

OIL FILTER

I only use the Purflux filters. They are OE (same a Genuine, but without the Mercedes logo). The zigzag shape of the filter material increases filter surface area.



Most, if not all, of my consumables (fluids, filters, wiper blades, etc.) I get from FCP Euro because of their Lifetime Replacement Guarantee. I pay once and then take the reimbursement on future purchases. This is especially true for the Magic Vision wiper blades on the SL--those things are damned expensive! Any durable, non-maintenance part that I expect to ever replace once, I first look for the best price.

TimC300

I shop all around for the lowest prices. Shipping costs factor in to it. if im already placing an order at eEuro or FCP then ill pick up a few $6 Mann oil filters while im at it. I only use fluids on the Mercedes approved list.

My car has records showing it was regularly maintained at MB dealers. I'll just follow the recommendations in the Maintenance Manual. Yearly oil changes, 2yr brake fluid flush, 4yr air filter change etc.

- Mobil1 oil- Local Walmart
- Zerex G48 50/50 coolant- Local Napa auto parts
- Febi diff gear oil- Local IDParts store (online store that happens to be close).
- Mann oil filter/ Air filter- eEuro or FCP
- Mercedes Dot4+ brake fluid- ebay 1 liter tins cheap.
- Shell ATF134- 6 pack quarts on Amazon around $45 shipped.

Mines a 2010 with over 150,000 miles, always been a New England car so the underside has wear/rust. I have saved alot of money buying used Mercedes parts off ebay from California salvage cars. I look for parts in great condition for cheap money. Not looking to restore the car, just keep it in good running condition for as long as possible.

I never touched the power steering fluid except confirm the level is full. i figure ill add replacing the fluid to my list.

I do hear a whining noise when driving especially at high way speeds which i was always wondering if it was the power steering pump.

My Operators manual says to use MB Power Steering Fluid ( Chevron Texaco PSF 9109). I cant find it for sale anywhere. I looked on the MB Bevo and there are no recommended fluids even listed.

What is the approval number? I see the Pentosin CHF 11S has MB Approval 345 on the label. Is that the right one, MB 345?

I was looking on FCP for what they recommend for power steering fluid and came across Mercedes Power Steering Fluid additive. i decided to see if they have it at my local MB dealer and they list an updated part # but it is labeled as Trans additive? Was thinking about getting a bottle and add it in. Wonder how much to add.

antboii

@TimC300 I had a power steering pump whine as well in my c250. I bought that additive from FCP and went to O'Reilly's to get the chf 11s.

I put the whole bottle of additive in and topped off with some CHF. I have not had anymore power steering whine.

I also asked my local MB dealership and they said the same thing. It's just a shot of transmission fluid.

This is why I don’t like hanging out here. I always find something I didn’t know I needed!

Levity aside, Googling Lubrizol 6178 says it’s a friction modifier, which makes sense if it’s meant to control whine. Appears to be for PS systems and transmissions, at least going by the above screenshots. I might try it if I remember to use it, as I’ve had a whine from the transmission when cruising at zero load from mile 9. Currently at 241k so I’ll know if it makes a difference.

TimC300

Im going to hold off on the Lubrizol. I looked at a pdf on it and seems its for if there is noise when steering to either side. The noise im hearing is a more constant noise, im probably over thinking it. Lubrizol says only use 1 time. if it has been added there should be a yellow dot on the cap. And if you do add it make sure to add a yellow dot on the cap. makes sense to let people know if its already been added.

I got a 1 liter tin of the Pentosin CHF 11S that happen to be on sale on Amazon yesterday. I just looked and its back up to $27 today.

Odd Piggy

Good catch on the 11S price. BTW — Don’t get that stuff on anything painted, if you do, wash it off with soap right away. And don’t spill it on any clothing you want to keep, it’s green, smells like wintergreen, and doesn’t wash out.
