I've an 06 2500 . Have been running 10w-30 . but found a sticker on my seat base, says 0w-40 Is due in a 1000 or so , One of the oil change shops i do work for says either is fine for where we are in the country . Any one know if you can mix weights as long as they are the same oil. At times when I have needed to add a quart I've not been able to find the 10w-30 .

Just like the old days the wt is environmental temp relevant. So you can use 0-40, 15-40, 20-50-5-30 whatever you like. If you’re in the tropics or the great white north, choose accordingly. What matters more these days is the additive packages in the oil itself. And these can be installed in conventional or “synthetic” based oils. I say that in quotes because there is almost no “fully synthetic” oil on the market. They are all blends to various degrees. If I’m chevron and want to sell more conventional oil, I can put 12oz synthetic into a 5000 gallon batch of oil and call it synthetic. That’s the marketing side, but where the water gets real muddy is that there are in fact fully synthetic oils that perform WORSE than a conventional oil with a superior additive package. So, short answer is it really doesn’t matter what wt oil you use, and the long answer is that choosing is extremely difficult based on many other factors.

I have 5 cars, a boat and several motorcycles. I’ve decided that I’m going to run synthetic blend 5-30 in all of them from now on. Except maybe my snow bike because it has a rather picky transmission that seems to prefer 0-40 but that’s not relevant to this discussion.

Pressure fed engines are actually not that demanding on oil it turns out. People think of oil as bein the slipperynthat keeps metal parts from touching and wearing. That’s only partially true. Oil has other jobs like cooling pistons, and absorbing acids and combustion byproducts and holding it safely away from metal. The pressure fed bearings in an engine would be just as happy running on water as a lube! So, that’s why additive packages make a huge difference.

Exceptions to this are in some diesels like fords where high pressure gear pumps create insane shear forces on oil but our sprinters don’t have such demands. One forum member here decided to never change his oil, and he was over 750k mi last I heard. What would really help the most would be to install a fine particle bypass filter system which would clean the oil more than our stock filters do. But, again, not relevant to this discussion.

You can mix weights for top off even if they aren't the exact same brand of oil, as long as you stay with quality turbo diesel oil.

I mostly use 0w-40 or 5w-40 MB229.5 or MB228.5 labelled oil. It comes in 4 quart jugs. I add 1 quart of 15w-40 MB228.3 to total the 9 quarts I put in for my oil changes. When/if I need to top off before an oil change I use 5w-40, 0w-40, or 15w-40 diesel oil... whatever I have on hand.

Added:
If I lived near the arctic I would not be mixing anything with my 0w-40 or 0w-30 oil, but I presume you live in the lower 48 states.

If you mix a quart of 10-40 with a quart of 0-40 you’ll have two quarts of 5-40.

And here is MB's take on what weight to use for what ambient temperatures...

Remember that you want *diesel* oils.

If you look in the owner's manuals, they have a list of recommended/approved oils.
You can download some owner's manuals from: http://diysprinter.co.uk/reference/

Maybe.

I don't know if it quite works that way, but as a practical matter it's close enough. The viscosity ranges are engineered using various additives so a given mix may not produce a true linnear result.

But...
That's an oil thread comment so not to be taken seriously.

As Dick commented, the important thing is staying with turbo diesel oil and basic ranges in Cheyenne's link for viscosities.

...which is why I use 0w40 exclusively. Temps here range off both ends of that chart...

What specific 10W30 have you been running?

I have used Valvoline 0w40 and Mobil 1 0w40 in my 2005 Sprinter both with good results. I live in the middle of Wisconsin with moderate to hot summers (90-100 degrees occasionally) and absolutely brutal winters (temps often below zero down to -30 with -50 wind chill at times).

I am also a big fan of Valvoline MST oils, you can pick up 5w40 at Walmart for $7 per quart. Their 5w30 MST can be had for a mere $4.22 per quart ordered from Walmart online. Both meet all of the current top specs for MB. I purchased a 5 quart jug of Valvoline 0w40 last time because it was on sale at Walmart for $18 with a $5 rebate. I recently bought four 5 quart jugs of Mobil 1 because I could get four $12 rebates. Be on the lookout for good deals and special promotions, there is always something going on with motor oil rebates.

ok, head's spinning a bit while researching my first oil change in our new (to us) 2012 3500 w/103k mi.... i am just a light diy'r that likes doing basic maintenance that my dad taught me.

#1-what viscosity for colorado driving? today it's 88F on the eastern range and we drive in the mountains in the winter at ~15-20F.

#2-when shopping for oil online how do i know that it complies with 228.51/229.31/229.51? how do i know that it is 'diesel' oil? costco sells 'Mobil 1 Full Synthetic Motor Oil 0W-40 European Car Formula' at $4.78/qt but all the reviews are from car owners. i get the distinct feeling that this is NOT what goes in my sprinter.

#3-what filters are adequate? i buy Mann for our Audi. where do you guys purchase filters? i shop a ton on ebay and amazon and advance auto parts etc. and look for the best price of course but want to be sure that i don't sacrifice quality.

#4-do i want to put on the e-z drain valve in the oil pan that i purchased online that replaces the drain bolt? don't they help direct/ removal of old oil with a length of appropriate?

thanks y'all. any and all tips are greatly appreciated!

Crispi,

Your 2012 is an NCV3 and you have asked this question in the T1N section so you may get better replies by re-posting in the NCV3 section.

Mobil One since new , have never had to add a drop between changes . never had any other car or truck like that

I hear ya...! I had a good head spin getting ready too (BEVO is such fun, eh?)

Don’t confuse the full-SAP oils (which make more ash and will clog DPF filters and may poison the DEF cat converter) with the low-SAP oils that your van requires. The T1N doesn’t have a DPF, so we often use the Mobile-1 Euro Car Formula which is a full-SAP oil meeting MB-229.3 and 229.5, but it should not be used in a DPF equipped vehicle.

The 22x.31 and 22x.51 oil specs you list are the appropriate ones for you to look for. Note that the 229.xx oils are simply “different” than the 228.xx ones. A higher spec number is not always “better”. I simply check the oil maker’s web sites, where you will usually (eventually) find a specification sheet that lists the “OEM approvals” of the product. If “MB-Approved 229.31” (or other number) is on the label or product sheet, it’s fine for your engine. Note that these OEM approvals are weight specific, so a 5W40 may be approved while the same product in a 10w40 may not be.

Always select oil weight by ambient temperature at startup, likely 0w40 or 5w40. Ignore the wind chill, humidex, or other “feels like” numbers. Engines don’t have feelings. ;-) (radiators like humidity... it increases the heat capacity of the air flowing past the fins)

If unsure what a quality filter looks like, you may wish to source your first filter from a MB dealer for a baseline. I use MANN on my T1N.

I hope your NCV3 gives you many years of great service!

locksmth72,

OK, Mobil 1 ("Mobil One since new") but WHICH Mobil 1?
For your 2006 T1N Sprinter with the OM-647 5 cylinder inliine engine, Mobil 1 European Car Formula 0W-40 (or 5W-40) would probably be the best!
There are lots of different oil formulations/blends that are "Mobil 1 Products, but only a few are the correct oil MB BEVO 229.5 for your 5 cylinder OM-647 Turbo diesel.
MB BEVO 229.5 does not list ANY 10W-30 oils under that 229.5 approval number.
Suspect you have been using a passenger car (NOT A Diesel) Mobil 1 blend.
Look at your Dodge/Freightliner Owners Manual and see what the Mercedes BEVO specification is recommended.
I put 100 k miles a 2006 3500 (lots of heavy duty 11,000 lbs. towing in the hot summers in the MIdwest and
had no issues using Mobil 1 European Car Formula 5W-40.
The van is probably still running around somewhere but I traded the wreck in on a 2010 MB Sprinter 3500 after a
major deer crash.
