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?

Heres a link an old thread. http://www.thedieselstop.com/forums/f33/what-add-fuel-lubrication-256769/

Do they make the diesel kleen in a smaller bottle so you don’t need a funnel?

Hot Shots Secret EDT in my '01 Duramax. 1 oz for every 25 gallons of fuel and it costs less than the others.

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.

Colder weather has a horrible effect on bio diesel. B20 (20% BIO) is pretty much the most you want to run around here. You may be able to run a higher % in the summer time.

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?

[n_mathews13]

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.

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!

Maybe I missed it, but what fuel filters should a guy consider?

Anything but stock filtration.  Newer trucks have stepped up but...  For example Bosch makes most injectors in these trucks.  Bosch recommends under ?4 to 3 micron? filter for their inj.  Then Dodge and Ford make their trucks with 8-10micron crappy filters.  Inj go bad 125k later or a bad tank of fuel.  Research your own truck to see what filter the factory has blessed you with!  Many upgrade lift pumps with filter system combo, like AirDogII example.  This is whats on my truck currently.  Like SpecialT the Wix/Napa filter base for $50 is a good upgrade as well.  I put that on my old Dodge.  Worked perfect. Donaldson, Wix, any spin on truck filter under 4micron is good idea with 2-3 being best!

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.

If you believe it works then the marketing has done its job.
