W124 230E Oil type....? Any Help ?

[imbck666]

Hi all

W124 230E 1990 Pre facelift Black top engine i have.

Just wondering.. been reading a lot of posts on MOBIL 1 oil etc...
My car is next due for service next week so was wondering is Mobil 1 any good for my car???
And what spec will be most suitable because at the moment its 10W-40..

Will mobil 1 be suitable to use ... maybe 0W30 i heard was good??

Any help would be kindly appriciated.

Regards )))

What's the mileage of your car and is it burning any oil?

 

[imbck666]

157,014 exactly no its not using any oil at all...

I would personally recommend Millers XSS 10w/40 semi synth or shell helix 10w/40 semi synth.

 

[wemorgan]

My personal preference would be to use a 10W-40 fully synth, but if that's hard to find then a 5W-40 fully synth.
A 0W-30 seems too thin across the temperature range to me. I think it's more common to use that oil in modern low friction/high effeciency engines.

edit: I'm sure Ian is is right It's debatable whether an old non-turbo engine really needs fully synth oil, especially if it's changed regularly.

Brilliant... will definetly look into that...

I guess 5W-40 is a heavier oil then? so better

If it's any help, after extesive searching, I ended up using Fuchs Titan 'supersyn' 5-40 (Mercedes-Benz 229.3) for my 101k 124. I used to change mine every 6k with mineral or semi-syn oils,,,,, but I only do about 4k per year.

For your vehicle it looks like Fuchs Titan XTR will suit - (with MB 227.5, 229.1) - but please check for yourself.

I'm sure others will put you (& me) right if this is wrong.



I'll be asking the same question as you now, but for a 220CDI (211) '07.

good luck

There's a nice write up on oils here:

Thanks ever so much for all help...

Im still lost as in which one to use :S:S

That's the thing about the internet......more opinions than you can shake a stick at

I use Mobil 1 (£23 for 4-litre tubs at Costco), but I bet regular changes at sensible intervals are more important than grade or brand. For some views on all this, try:

oooops,,,, link dosn't work for me.

 

[imbck666]

works for me..
Not much info on my w124 though:S

Guys shall i go for 5W-40 a heavier oil then or 10W-40 a lighter oil

 

[wemorgan]

Buy a 10W-40 that meets 229.1 like Fuch Titan XTR.

 

[imbck666]

coool..

I will buy 10W-40..

Just to ask why not 5W-40? just out of curiosity...

 

[grober]

The figures 5w40 means the the viscosity (thickness) of the oil varies from 5 (thin) when cold to 40 (thick) when hot. 5 is good because the oil flows nicely when the engine is cold, lubricates everything and is easier to start. 40 means it thickens up to keep its lubricating qualities even when hot.[ its more complicated than that but trying to keep it simple] So a 5w40 oil has a wider "range" of performance than a 10w40 so technically is the superior oil. The downside of a 5w40 is its usually slightly more expensive and if your car is getting on a bit tends to leak a bit more thro any worn seals. A good semisynthetic 10w40 changed every 6,000 miles was the oil technology available when the engine was in mainstream use and suits the car's engine IMHO Going for a higher performance fully synthetic oil will give you slightly better cold starting and means you could theoretically extend the change interval to 7,500-9,000 miles but will cost a lot more. These synthetic oils are manufactured for the finer tolerances of modern high performance / turbocharged engines and you won't derive the appropriate cost/benefit by paying twice the price for your oil.

Fuchs or Millars both make very good semisynthetic 10w40 oils at reasonable prices as has been said already.

wow what an explanation!

Thank you so much
Kindly appriciated

In UK temperatures the 5W-40 oil will be thinner when you start your car. For an older car with high mileage I feel that a thicker grade (10W-40) would offer more protection.

This is just my personal view and I could well be completely wrong
