How does bio-diesel (both 20% and 100%) affect the Mercedes-Benz diesel engines? I've heard that they result in pre-mature wear of rubber components and other negative impacts. Has anyone had actual experience with long-term and/or consistent use of bio-diesel in a recent vintage (post-1990) Mercedes-Benz diesel engine, either in a passenger car or commercial vehicle, who can verify one way or another? Appreciate the insights...
