If you use opie oils don't forget your 10% mercedes discount
My question was more aimed at low weight oils, ie 0w5 and pressure loss rather than viscosity range. Ian did answer and assured me that 40 weight oils thin down more under heat than the fully synthetic lower weight oils. I couldn't use low weight oils in my P38 Range Rover because of the pressure loss, which was largely down to worn main bearings. The camshaft was also shot and also the cam followers obviously. A lot of damage for a lazy V8 with less than 100,000 miles on it.
Sorry. 0w40 not 0w5.
Can't edit on my phone.
When i bought my SLK 350 early this year, the dealer did an oil change on the car, god knows what chippy oil he put in it as it drank it quicker than a park bench alky drank a cheap can of white lightning, i panicked and changed the oil for Shell ultra 5w40 and the car has not used a drop since, i also use this oil in my ford ranger pick up and it loves it and uses non between changes, i swear by the stuff
Was it a main dealer?
If i have the right can its not to expensive which is nice.
Was it a Merc dealer who serviced it ?
That is MB229.5, you need MB229.3, look at the Castrol on the opie oils link I posted
No, just a trader but what looked to be a decent one who sold sports and prestige, but i later found they had took the car to a back street garage for the oil and filter and mot, so i presume they used oil that was not right for the car
Yeah.... same here, small garage, had the oil in for less than 1000 miles but im pulling it out to be sure.
>>>small garage, had the oil in for less than 1000 miles but im pulling it out to be sure.
When we bought the CLK recently I was pleased the small dealer allowed a deal where I did the slightly overdue B service myself so I know all the oil and filters are actually done... and proper quality.
I take it its ok to use 229.5? It would just exceed the minimum standards, right?
Any if you buy that Shell on the Ebay link it's made from nice clean gas with no nasty lumps of coal in it.
Straight answer anyone, can 229.5 be used instead of 229.3? Or is that wrong?
I think you will appreciate seeing the "horses mouth".
Look at this MB link... http://bevo.mercedes-benz.com/bevolistenmain.php?language_id=1
Open the sheet near the top 223.2 and look for your engine code. Then read off the approved oils.
If I'm right you have a M271 engine then it states oils including 229.3 & 229.5 are OK.
Opie oils describe the various MB oils here...
Yes to a great extent, but with older cars the modern oils are maybe too thin and will be burnt away as these older engines, with wear and wider tolerences need a thicker oil to seal those looser and higher mileage engines.
There is also a much better cleaning effect with the newer up specced oils so this as well could be the the detriment of older engines, as many of them work well with carbon deposits etc. sealing up the necessary bits n bobs.
Though no reason why you cannot go to 229.5 from 229.3.
Just having a cruise around the web re the MB oil types and came across something in several forums that I've never heard mentioned.
The main advantage of the 229.5 over the 229.3 is a longer drain life. But... and if true a large but... the extended oil life can only be used if a fleece (polyester I think) oil filter is used not a standard paper one. They say the standard paper one should not go beyond 12,00mls. I see in Google images many genuine MB filters are white rather than yellow of the paper ones... wonder if white are the fleece ones?
Anyone heard this?
Ive read the same. I believe 229.5 can be used with paper, its just the paper will wear out before the oil.
Yep seems so. No problem as we will be changing around 10k anyway on the CLK. I've no way of checking but I reckon the ECP Bosch filter I fitted was a yellow paper one. As a matter of interest I have seen a paper filter (the element type like our MBs) on a Peugeot that was left in for almost 30k start to disintegrate so unfiltered oil could pass through.
