Hello all. This is my first time ever asking question on a form....

I have a new Jeep Grand Cherokee 3.0 ecodiesel... for years in I have been making and burning Biodiesel in other vehicles. I would like to test out what will happen with the new Jeep. I understand that I can use up too B20. Have anyone tried this? Has anyone tried to burn higher? Does anyone think they would know what would happen if I tried?
Many thanks all

Ed

saw this:

WHEN USING BIODIESEL BLENDS GREATER THAN 5% (B6 TO B20) - Under no circumstances should oil change intervals exceed 8,000 miles (12,875 km) or 6 months, whichever comes first.

Thanks! I wonder if that's because bio starts to build up in the crankcase and thins out your engine oil. I wonder if that's the reason that they don't want you to exceed 20%....
Maybe with more than B20 it doesn't completely burn when, and if, diesel is sprayed in the downstroke and into the exhaust system.

I know what will happen... you'll void your engine warranty.

Read your diesel supplemental manual regarding fuel types. :)

I read that....

But why? What happens??

I found this reply on the internet, supposedly from Jeep Engineering back in 2008...

We understand the desire to run bio-fuels, and we would like to do so in the future. There are 2 main issues with using bio-diesels more than B5-B20.
1. Cold start - biodiesel fuel have significant issues with gelling
2. High pressure fuel system durability - biodiesel lubricity is not well controlled

When the fuel industry have a standard for the fuel so the lubricity and chemistry of the fuel are standardized, then we can really work on solving the remaining issues using bio-diesel fuel.

I'm no expert on biodiesel fuel. Does any of that make sense to you guys?
