Bio Blend B20 ok for my Cummings X12

[Ponygail]

I have a 2022 Moutain Aire. Can I use Bio Blend B20 diesel instead of Ultra Low sulfur? Manual says talks about using Ultra low sulphur only. I stopped at a Pilot and a Chevron today and all pumps labeled Bio Blend B20.

Yes, BioBlend is still ULSD and it is all that available in most locations.

Ditto!

All road-use diesel in the USA is required to be ULSD

Diesel #2 is fossil fuel based diesel. Pumps with no sticker are B5 or below.

B20 bio diesel is up to 20% Bio stock 80% fossil stock. It's mandated in several states, and significant tax incentives make it a default fuel in many mid-west states("Thou Must Burn Our Farmers' Products!"). Bio-diesel stock is chemically processed, not refined.

R99 Renewable Diesel. Starts with renewable stock (plant or animal) and refines it. The closest formulation to Diesel #2 or dino diesel that's renewable. California is the only state where it is generally available.

R80-B20 A rarer blend of 80% R99 with 20% bio-diesel.

Mercedes warns against continuous B20 usage in Sprinters before the 2023 model year

"B20 is not recommended and if the customer must use it due to availability in certain states, additional maintenance (more frequent oil and filter changes as well as fuel filter changes may be beneficial). Fuels with more than 5 percent biomass content are not recommended."

Is Bioblend B20 different than just B20? From my understanding B20 is not ULSD and does not meet the ASTM D975 standard, and is not recommended by certain engine manufacturers. Mercedes (certain years) and the OPs manufacturer specifically says to use only ULSD (B5) and to avoid B20 which is not labeled ULSD.

All ULSD has the green ULSD"up to 5% biodiesel" pump label while B-20 does not qualify for the ULSD label. In other words, while the 80% part is made up of ULSD, the B20 mix is not identified as a ULSD fuel and doesn't meet ASTM D975 which is a requirement in order to be labeled as ULSD and is not recommended by the aforementioned manufacturers (for certain years).

Renewables such as R-99 and R-95 do meet ASTM D975 and are identified as ULSD.

I haven't heard the term Bioblend so asking if it is just another name for B20 or R-99/95, or something totally different? If it's just plain B20 than no, it's not the same as the B5 ULSD sold most places, it won't have the green ULSD pump label and is not recommended by the OP's manufacturer..

We did a lot of research on this at the Sprinter forum a couple of years ago including Zoom calls with 2 refinery engineers. The term Bioblend never came up.

All diesel fuels in the USA are required to be ULSD.
Unmarked pumps are Diesel #2 with up to 5% bio-diesel.

At several truck stops, I have seen the truck lanes with B20, but the auto lanes will be diesel #2.


EPA regulations

Onroad (Highway) Diesel Fuel Standards
From 2006 to 2010, ULSD was phased in for onroad diesel.

After 2010, EPA’s diesel standards required that:
All highway diesel fuel supplied to the market be ULSD; and
All highway diesel vehicles must use ULSD.

Nonroad Diesel Fuel Standards
From 2007 to 2014, low sulfur diesel fuel (specified at 500 ppm) and ULSD fuel was phased in for nonroad, locomotive, and marine (NRLM) diesel fuel.

After 2014, EPA’s diesel standards require that:
All nonroad, locomotive, and marine (NRLM) diesel fuel must be ULSD; and
All NRLM engines and equipment must use this fuel (with some exceptions for older locomotive and marine engines).

Wow! All these alphabet letters... You all lost me completely on this post. If it's at the pump, I just use it. Of course, my truck is over 10 years old now too.

Remember the days when diesels would burn just about anything! Including left over cooking grease? Sift out all the cooking and food crumbs and the cooking oil would burn in a diesel engine. I remember the days when folks would go around to restaurants, like McDonalds, and volunteer to remove the grease they collect or replace for their French fry vats and such. They'd take the grease, sift it, and burn it in diesel vehicles. Gone are those days for sure! Try that now and watch the environmentalists go bananas!

Of course, burning left over French fry grease in your diesel engine also smelled a lot better too!

I never fill up without adding Diesel Kleen it is the only additive recommended by Cummins. I use Diesel Kleen +Cetane Boost (in the silver bottle) for peak performance in non-winter months and the white bottle in cold temps.
