B5 how much lube?

ken · Dec 9, 2007

I've noticed alot of gas stations here are starting to get the B5 sticker on the diesel pump.
I know bio has more lubercation than the new ULS crap they are selling now days. But, how much more lube could B5 be? I'm guessing they are using it to help reduce emmissions even more. I use lucas fuel treatment in my 6.2's to help with lube. But does B5 help enough to consider not using the lucas?

Biodiesel contains oxygen and will improve combustion some. With the ULSD, I use at least 10% biodiesel or veggie oil.

I thought that the bio had a higher solvency which reduced lubrication?

NO, it increases lubrication. It is a natural solvent.

Ken, 5% is not a lot of biodiesel. It won't hurt to keep your additive.

P.S....

1% biodiesel will increase lubricity by 65%

From: http://journeytoforever.org/biodiesel.html

The addition of biodiesel, even in very small quantities, has been shown to provide
increases in fuel lubricity using a variety of bench scale test methods.

From: http://www.biodiesel.org/pdf_files/fuelfactsheets/Lubricity.PDF

I can provide may more links. People need to get their fact straight about biodiesel and stop guessing. It's a good thing!

Bottleworks, That's the kind of info i was looking for. Thanks, I'll keep using the lucas. Your right 5% insn't much. But i guess it's better than nothing.

Here's a study on fuel lubricity additives. Hands down, B2 bio showed the best improvement to adding lubricity to diesel fuel.

The .jpg is the summary, the .pdf is the 10 page or so detailed test report.

I got this from TheDieselPlace.com, poster/tester's name is "Spicer".

Enjoy.
