Some of the gas stations around here sell a 20% bio diesel fuel. Anyone have any experience with it?

Used it in my 06 a few times and had more soot out tail pipe when driving & not towing, saw no mpg improvement some claimed to get so only used when I had no other choice when traveling, around my area B20 cost the same as B5 so will still avoid it in my 22 as I see no advantage to using...

It messes with the fuel filter on my Eco-diesel

Many of the truck stops are switching to bio-fuel
I now hunt down the stations with #2 diesel

they claimed that it would be cheaper than #2 diesel
we now know that is very seldom true

Ram also recommends to change to engine oil at shorter intervals when bio-diesel is used in the vehicle.
On the good news, bio-diesel usually has a higher lubricity to it than ULS #2 diesel so it should be better for the pumps and injectors.

Yes, the bio-diesel has lubricity that the current #2 diesel fuel lacks, but in fuel mileage tests (can't remember who performed these tests) it was substantially lower than straight #2 fuel. I run #2 with 6 oz. of Power Service Diesel Kleen in my 2011 CTD and have no interest in changing.

Going to resurrect this a little.

A gallon of diesel here in Cincinnati is 5.70-5.80 at Kroger. Across the river in northern Kentucky its 5.17 at Kroger, and at the Costco in Florence, Ky they had Diesel with "up to 5 % bio diesel" blend for 4.49 if I remember correctly. My Cincinnati Costco doesn't even have diesel and was surprised to see a diesel pickup pull right in the last time I was there at the one in Florence.
I'm guessing the Ky Krogers have that same blend but will check.

So for a dollar cheaper and only 5% bio diesel, would you fill up, or is 35 bucks a fill savings still not worth potential problems?

I’d do it for 35 bucks @up to 5%. I don’t like it still, but gotta save a little. 2 fills almost pays for filters.

Around my area 99.5% of stations sell 5% Bio Diesel so at times I have no choice but to use it when the non bio diesel station price can be 50 cents a gallon higher then Fred Meyers/Kroger, in my 2022 I do not notice much difference in fuel mileage when using B-5, now in my old 06 5.9 CTD I would lose fuel mileage when using B-5... I have had many diesel owners here locally say that good B-5 diesel is ok to use when towing long distance but its not good to use for town driving... As for filter problems I have been lucky not to have any and in the cold of fall/winter I always use anti-gel additives it any time temps will drop or may drop below 30 degrees, is it over kill, maybe but I don't like the idea of having to mess with a gelled fuel system..
