adding bio to diesel
 

I want to start adding b50 or 100 to a full tank of #2.
will the bio blend with the diesel if I just dump it in at fill up or is there a better way of mixing it?

Just dump it in. It'll mix just fine.

Making your own? Come winter you may need to do that anyway, depending how cold it gets... I am at about 70% bio now, still getting down into the 30's.

Buying not making. Just using it for it's lubricating properties in my 6.0, how many tankfuls before changing fuel filters - say if I run a B5 blend ?

In my 6.0 i have been doing it on the second oil change. So about every 6-8 thousand miles. That may be a little much but I really have way to much money in it to have somthing go wrong from a bad filter. You should be good with normal change intervals with b5 blend. If you notice loose of power i would change imediatly. Pluged filters and or not enough fuel pressure will kill every injector with no murcie.

been there & done that ... really need to avoid injector failure .... that's why I'm asking
thanks again

glad I run an idi just carry spare filter and change it when she starts to surge, if it ever hurts an injector whole set is $200

WOW - 200 won't even get me one injector

Funny, this just happened to me this trip. Changed the filter and ran like new again. About 15000 miles on the filter, I was going to change it after i came home...
