B20 Diesel Approved?

Is B20 diesel approved for my 2022 Cummins 6.7?

The manual is vague about the B20 capability as it simply says: "This vehicle is fully compatible with biodiesel blends up to 5% biodeisel meeting ASTM spec D-975. Pickup models configured with optional B20 capability, are additionally compatible with 20% biodiesel meeting ASTM spec D-7467."

So, how would I know if my pickup model is configured or not for B20?

Lots of B20 pumps where I live so I have to strive to find ones that are not B20 until I can confirm this.

Searched the threat and couldn't find anything on this.

Thanks!

I saw that too, but found this; Page 396 in my 2022 3500 manual. B20 is approved. The stipulation is that oil change frequency cannot exceed 6 months using B20. Mileage remains the same. Screenshot_20230507-090355.jpg

I'm in the midwest and most of the pumps around here are labeled B5-B20, so who knows, it might be B20. I don't think I've ever had any trouble with it though.
 
I dont think i have ever seen a B20 pump here thankfully i did not know they were that common down there
 
My 2020HO is approved for 20% Bio, I'm sure your 2022 is as well.
So far the Feds have limited diesel to a 20% maximum blend.
Nothing wrong with Biodiesel. It adds lubricity and cleans the fuel system. The negatives are it doesn't get the mileage that regular diesel gets and the oil should be changed earlier. Not sure what "premature wear" means as I've never read about Bio causing premature wear.

I have changed to 100% Renewable diesel in both my Eco and my 6.7.

The major drawback on bio, as far as I know, is if it sits in your tank for an extended period of time, it's more likely to start growing some nasty stuff that you want nothing to do with.

I've ran lots of it and I agree, it's fine if you turn it quickly. When I run 70-100 gallons a day, it's not an issue. But I go out of my way to ensure I don't fill any of my equipment with it that may sit for a while without using much fuel. Some stuff around here sits for over a year without running much.

What do you mean by "the feds have limited diesel to a 20% maximum blend"? There are pump where I live that say the fuel is 95% bio...so B95. So far I have only pumped from pumps that don't say anything - which as I understand it, means it could be up to 5% bio only.

Thanks, I see that now in the manual. They have done a pretty poor job writing the manual with contradictory info as well as scattered info through out the manual.
 
There are also states like Minnesota where the on road diesel is all bio. I think it's B20 in the summer and B5 in the winter mandated by law.

A bio blend higher than 20% is not for vehicle use. That's why Califunny has a law restricting Bio to a 20%. The feds state that BIO higher than 20% blend it is not a transportation fuel. Federal Bio Diesel Data.
Are you sure your local 95% blend is Bio, it could be Renewable which is often a 95% blend.

It’s not super common but B95, B99, and B100 can be found at the pump. I’ve never seen it, but you can find the fuel stations online that have it.

Is this because they thinking 100% is cooking oil some people run? and there is NO road tax on it? You know Cali, always looking out for there tax revenue.

The link explains it.
Any fuel used on a public roadway is taxed.

I'm sure its different in different locales but here in my little portion of paradise (KS) if you use any kind of fuel that doesn't come from a taxed pump, such as propane, you just buy a tax stamp and you're good. Back when I burned propane, it was a steal. That stamp was only like $25 or $30.
 
The biodiesel industry has had 2 government subsidies to help it gain traction, an EPA program and an IRS tax credit program. The B99 isn't very common any more, but as John said it was to make sure it was counted in those government programs, taxed and accounted for. The 1% diesel doesn't do anything functionally, just was a rule they had to follow.

Nothing wrong with biodiesel, isn't going to harm anyone's truck if you use B5 or B20. I wouldn't use B20 in even a moderately cold climate though. And if you have a friend that "home brews" biodiesel, I wouldn't use that in a truck, only for heating oil. Biodiesel plants have to pass a variety of test standards, a backyard producer won't be the same quality.

Renewable diesel is taking over rapidly, not sure how much biodiesel production will be left in a few more years.
