This is one of the least of my worries and does not prevent me to have a fourth Class B built on the Mercedes Benz platform.
It's just my opinion, and that was what was asked, but this is what it is based on:
As for B30, there are fuel stations all over the U.S. with B20 or greater up to B100. I only learned this myself when I pulled into a truck stop pump in Texas and had a trucker warn me about using B30 in my Sprinter RV - there where no signs but the traditional stickers on the pump. Here is the government map of where you might find these stations.
As for higher than B5 (from the 2019 manual): "B20 fuels with bio-diesel content. NOTE Damage due to incorrect fuel. Continuous use of fuels with bio-diesel content over 5% (B20 fuels) can lead to fuel filter clogging. Deposits may also form on the fuel injector. This may reduce the engine output. Unburned fuel can get into the oil pan. This causes the engine oil level to rise. This can cause engine mechanical damage." Can you run B20 in it? Sure. I've had a lot of problems with mine before I understood this (who reads manuals cover-to-cover?). As for the warranty, when I was considering a 2019, I called MB in New Jersey, (800) 367-6372, and was referred to a "product specialist" who said it could void your warranty with "continuous" use as it pertained to the engine. Also note, that on all new shipped Sprinters is a sticker in the fuel filler area that says, "Use only Low Sulphur Diesel #2 or B5 in this vehicle." If you go to a dealer, you will notice most if not all of those stickers have been removed.
In Minnesota, supposedly it is to be illegal to sell under B20 according to this law: https://mn.gov/commerce/industries/fuel/biodiesel/
The reason Minnesota has this B20 law is because of environmental concerns. Now, I'm no tree hugger but the chances are pretty good we will see more of similar type of laws in other states. What I don't get is why Mercedes-Benz, and they are not the only diesel RV chassis with this problem, does not make their engines compatible with B20 and higher, as this is clearly where the sentiment is going. I don't want to end up one day having a white-elephant that is even more expensive to care for because I can only get B20 or higher fuels. All considered, if I had another choice, I would not have purchased a Sprinter-based RV.
