Did I used the right Oil ?

[Bellow]

Best to say "oil right then"

Indeed. Minus 1C and the 10W/30 impeded the SBC not one bit!

I wouldn't use it , and as for your 15W40 viscosity... we use 0/5W-30 C3 in our Euro 5 and Euro 6 diesel Mercs , you are not going to convince me or anyone else here Mr Bellow to start using 10W30 or 15W40 heavy truck oil .

So it's best you discontinue your retarded futile crusade .

In both my MB’s , the E320cdi and the CLK200 I just use any oil that says 229.51 or 229.5 written on it .
I‘ve used the bulk MB cubes , Castrol , Shell , whatever is in a sale that I can get cheap . Currently working on two tubs of 20L Mannol at the moment that I got crazy cheap on eBay .
I normally just change the oil and filter every 6k whenever it comes up which is normally 8-10 months
.
As I have non understanding of oil whatsoever that’s my solution.

5 pages over oil? There's a guy on Youtube who commits mass genocide on lawn mowers so that you can learn everything you need to know about oil. Look up Project Farm

That's a great channel .

For that to happen someone would of had to test under the same conditions both your 10W30 Monolec Ultra Diesel oil and a VW 504.00 507.00.

Do we know in what way does the VW oil not meet MB229.52?

I am assuming it doesn't meet the MB spec on at least one aspect of the spec, or VW would have included the MB spec in their oil's spec list?

 

[Gazwould]

229.52 exceeds in fuel economy , 504.00 507.00 exceeds in wear protection , you can't have both .

229.52 exceeds in fuel economy , 504.00 507.00 exceeds in wear protection , you can't have both .

Isn't this trade-off determined by viscosity, rather than by oil spec?

 

[Gazwould]

You can have both but it's a rare combination like Mobil 1 ESP and a hefty £50 from Opie Oils.

Down to ingredients , more expensive for one oil to then have an almost complete performance profile .
