Usually Diesel Kleen, I only add some in the winter when it gets real cold and occasionally through summer. Is it really needed all the time?
That’s what I’m trying to figure out as well. Everyone I know tells me to add it every tank

My buddy who’s a major Cummins fan recommend Diesel Kleen when I asked this question in regards to a 99 VE Diesel Jetta. I believe it’s helped increase mileage a few mpg. I went from 42-43 to 44-47 with occasional 52 on a long road trip. Seems to keep things cleaned out
Those Jetta's got amazing mileage! :tup:

So many different opinions on this stuff. We have a lot of people that come here and buy the Motorcraft cetane booster.
Have you ever heard of any studies or manufacturer recommendations?

Bio diesel has better lubricity and cleans your injectors etc. I run it any chance I get. Lots of people say better performance and mileage too.I have to disagree with you in that. We run bio in all of our rigs at the state and if you pull a fuel system apart there is nothing put brown sludge in the filters and fuel line. Bio also attracts water. We replace more fuel filters because of water in fuel. I would love if we didn’t have to run it but it is state contract. Also we run a higher blend of bio then what you get at the pump. But in my option bio fuel is crap.

The DOT ferries ran high bio% & had all kinds of problems. Funny how even if you have a heater in the fuel tank you can't get it warm enough when one wall of the tank is the ferries hull.

archoil is what I have put in mine. Along with the oil additive. Saw better miles per gal since I switched
How much better mpg do you see?

Now I can get on board with that. Admit cetane boost increases mpg slightly but not really to offset cost much. Running Amsoil in this cummins and engine does seem more free so to speak. I think injector lube is most important when talking fuel additives but good fuel filters is where all of your $$ should be being spent if ya don't have it. Cant stress this enough. This should be the FIRST thing anyone buys for their diesels! :twocents:
Maybe I missed it, but what fuel filters should a guy consider?

I used to put Racor filters on my duramax but got tired of fighting with the gasket so now I use either Baldwin or AFE. Any 4 micron filter should treat you well.

I went on a trip with just diesel additive and it didn't change much. Then a week later I went out of town again with diesel and oil additive and it increased by 3 mpg better. I run it in almost every tank.
Wow that’s a nice increase! Especially with the cost of diesel now

I would only use Racor or AC delco on your Duramax or your looking for trouble. As I've stated they are a coalescing filter and your Duramax injectors are very finicky. The only other option I would consider is an aftermarket system that will trap the water before it gets to your injectors.

Baldwin is the best filter hands down. Smallest micro filtering. atleast for a cummins

I've always used Baldwin oil and fuel filters.
