Oil change

[Silas_Carpy]

I’ve read a million posts, am I over thinking this? My sprinter calls for mb 229.51 oil spec. P.o. Used pentosin hp 2 5w-40. It is no longer available in 5w-40. In fact, I can’t find 5w-40 locally, would have to order. The new 229.52 spec can also be used but they have even fewer at this weight. I see all kinds of recommendations for Mobil 1 esp 5w-30. I live in upstate n.y. But rv is not used in winter, buttoned up oct. and not started since. I read it is better to leave sit than to start up if you can’t take out for 35 miles or so. Why are all the mfg getting away from 40 weight? For this rv only used in summer it would seem that 40 would be beneficial but everything seems to be going to 30 recommendation. I can get the Mobil 1 esp 5w-30 locally, if I want to stay with 5w-40 I would have to order liqui moly from rock auto with an extra 25 bucks for shipping. Is everyone going to 5w-30 even for hot weather use?

2008 sprinter with the om642 3.0 turbo diesel. In as much as this is 14 yrs old, the oils listed in manual are no longer even produced so I am using the bevo chart recommendations. The mobil 1 euro car is not listed for this engine. The manual doesn’t give a specific weight recommendation, just choices based on ambient temp usage. It confuses me because the only change is at the low temp, all from 0w-30 to 20w-50 show the same upper temp range. So what’s the point in the differences? Like I said, I must be over thinking it, I guess either the 30 or 40 will work equally as well.

What year and engine in your sprinter?

Mobil One has 5W40 synthetic oil available now. It is called “European Car Formula”.
I see it in Walmart, Auto Zone, and Advance Auto Parts stores.
I needed it for my former Vespa scooter.

IMO you should follow your manufacturer's recommendation.
BTW Chevrolet specifies 0W-20 for my Silverado.
