I could tell the difference in the SDL. I used the thin oil in the
winter. (5w-40)M1 and the 15W-50 in the warmer weather. oil pressure
was lower at idle, oil consumption went up with the thin stuff, but it
started easier at -20ºF.

It's enough that a thinner oil couldn't be kept cool enough by the oil

Will it be a big difference though? 5%, 10%? At what point does that mean you
*need* thicker oil?
Also remembering that most of us don't run the engine at 100% output very much,
with a 240D you come close but still not all the time. For example when I'm
running the groomer it works 100% all

I disagree.

Does the engine temp rise appreciably with higher ambient temp? The engine is
already closing in on 200F, especially in the moving bits...
Didn't Mercedes say anything above 1 bar of pressure at idle was acceptable?

I agree. The inside of your engine is going to be way more hot than the outside
temp so the theory of needing thicker oil in hotter temps is false.

When the ambient temps are at and above 100F, a lighter than 50 weight oil
would not keep the oil pressure up at idle when the engine was fully warmed
up. 15W-50 synthetic was great in the OM61x and OM60x engines I had. So, if
the temps get high, you need heavier oil. If the temps get low, you
In a 61x engine 0w40 is hard to keep IN the engine. At least it was in my '83
240D. That car leaked 5x as bad with 0w40. It started more easily but was
costing me an extra quart of oil a week to keep going. 5w40 leaked way less and
started nearly as well.
I'd say 5w40 is the sweet spot,

M1 15W-50 is still best for summer and moderate winter temps. (OM
601,2,3) and still good for OM61x, although the soot levels dictate more
frequent oil changes, so, IMHO make OM61x not worth the price of
synthetic. I'd guess about 0º. Below 0, you probably need a garage, a
block heater,
A person used to be able to purchase it in the diesel oil section, the 20/50.

again but in the special motor bike section with a price
Clay I think, mentioned 20w50 the other day, I recognize that just because I
don't know a thing exists doesn't mean it exists. He mentioned both 15w50 and

some mysterious west coast M1 I've never seen. ;)

Oops yes M1 15w50 is what I meant. Sorry for the typo.
20w50 probably came to mind as I used to run Castrol 20w50 in my
air-cooled VWs years ago.

I don't think I've ever seen M1 20w50... I forget where you are but if the

able to go long OCI due to soot levels unless you filter for soot specifically

Wow an oil thread.
What are people using in the older diesels, e.g. OM617?
Years ago (Marshall Booth era) I used to use M1 20W50. I later got the
impression that it wasn't so great for diesels anymore, and started
using Delo and changing more often.
I have M1 20W50 in the 300SD now, mainly

I'm not sure I 100% believe it. My 2010 Dodge RAM certainly doesn't do as well
with Valvoline as it does with M1. Around 5,000 miles the engine starts to tick
on startup, change the oil, tick goes away. With M1 tick goes away and stays
away. 8,000 miles in now on M1, no tick.
