Hello JDN, thanks for the info. My first diesel so I'm learning as I go. I found this
article on the MN biodiesel mandating a minimum of B10. Apparently a big topic that had me concerned but no choice here. As you say, I'm hoping it is actually a better fuel. My 2016 manual does call for more frequent oil changes at 8k miles or 6 Months and filters at 20K or every year when running B6-20. I just turned 1200 miles and love the avg 25 MPG. I get an occasional whiff of diesel or DEF but I think it's mostly in my head!
Yeah if you spend a lot of time running around town and the soot content in the exhaust gets high you can smell the DEF burning off in the exhaust as it wants to do a regen. I'm in a very small town so my everyday errands promote no highway time and very little full temp time so occasionally I get a forced regen by the truck,
As far as oil and fuel filter changes, remember to drain your fuel filter on occasion. It's a simple task but it removes sediments from the housing. And a bit finicky to do with the factory drain because the canister gets airlocked opening a small drain at the bottom with no upper vent unless you crack loose the whole housing. And make sure you prime the fuel system after draining.
I change my oil between 7 and 8k and I drain the fuel filter at one and replace it at the other. Not a very troublesome task. There's a lot of room. And you just place an icecream pail or the lower half of any gallon size container which rests in the propshaft tunnel right below the filter.
Also there's a solid brass drain plug available from Geno's garage that comes completely out allowing the housing to drain much easier if you find it worth the hassle to switch.
Was my first diesel as well, you learn a lot and there's a lot to read up on on the forums.
