Bio-diesel or ethanol blends have been proven to not harm engines or components.
I have used ethanol blends in all my vehicles for many years with no problems at all.

Really? Pretty interesting statement considering every single diesel maker disagrees with you. You know something that they don't?

First there are compatibility problems.


Then there is the problem with the SCR and DPF systems.

Then there is post injection problems with Biodiesel.


Need I go on? And I didn't even talk about Alkie in gasoline! :R

Where do some of you come up with this stuff? The disinformation and misinformation on this forum is astounding! :R

if every single mfg disagrees, why are at least 3mfg certifying the current diesels vehicles for use with B15 and in most cases B20 and have certified use of B5 for more than 10 years.

yes, initially there were compatibility problems with high blends with seals, hoses etc. but those were adressed easily long ago and never was an issue with B2 of B5.

and none of the links you posted are from a vehicle mfg. paper yes, validity with VOE well subject to careful examination for sure before concluding anything. and at least one is 5 years old.

Every single manufacture says bio is hard on engine parts.

#1. Name one engine manufacture that recommends running 100% bio; or even 50% for that matter? Oh that's right, there is none. Do you know why? Because it's hard on engine parts.

#2. Look at the oil change schedule for straight #2 and then for a #2 bio blend. Oh, look at that; if it's a #2 bio blend you have to follow a severe oil change schedule. I wonder why that is? :R Do you know why?

#3. Bio is hydroscopic and holds water in suspension; how compatible do you think that is with a CP4-x pump? :R

#4. Not all people on this forum own new trucks. Try running bio or even a strong bio blend and see what happens to your hoses or rubber parts. Let me know how that works out for you. :B

#5. Not all people have old trucks on this forum. Try running 100% bio in them and tell me how it works out for your SCR and DPF for you. :B

#6. The manufacture of my truck says no more than 5% bio; PERIOD! Some states mandate over 5%. Some 10%. Do you think it's a good idea to go 100% over manufacture specs? What about 150 or 200%? Is that ok also? :R

B100, yes, I'll agree it is an issue with most vehicles. But there are also very very very few stations selling B100, or anything above B20 for that matter. But B5 is very compatible with almost any engine, and B15 or B20 is certified for use by the big 3 for the last number of years. And at least for my truck there is NO mention of changing ANY service interval when going to B5, B15 or B20 vs regular diesel. However there are multiple warnings about the dangers of using straight #1 or even small amounts of #1. So they do care about what you run and at least with my vehicles bio up to B20 is perfectly fine according to the mfg.

And like I mentioned, B5 and occasionally B20 for 150K in my 04 ended up with injector balance rates near the number when new, indicating very very little impact on the injectors, a very common problem with low lubricity, and again on issues with fuel filters, water seperation etc.

But get used to B2 or B5, because more and more states are mandating it, and often that means adjacent states and areas end up with it anyway.

Personally, I love the results of B5 and B20 so far in my vehicles. But granted they are rated to take both. improved lubricity, higher cetane number same energy content, all good stuff. you can really notice the cetane improvement on a cold morning start and cold engine much less rattle, even on the latest version trucks.
