I was getting some fuel for the truck last night and saw that the warning sticker on the pump had changed. Instead of the low sulfur warning sticker, Walmart now has a sticker on the pump stating that they are adding no more than 5% biodiesel in their fuel. Should I be happy or should I worry more about my filters?

 

From what I have read you should be happy, you may go through a filter or 2 untill your tank gets cleaned out of any crud, but it will run quieter and smoother and the fuel system will be better lubricated. I had my 11 year old tank open the other day and it was spotless, so you may have a clean tank and nothing to worry about.

 

Your truck will be ok. Its guys that run older trucks like me that may run into problems. I forget what it is but something in the bio fuel eats the rubber parts in the pump and stuff.

 

i think my trucks ran it's best from safeway fuel at almost 10% bio fuel, quieter and a little more MPG ( mighta been cause i stopped pushin the little pedal down so far )

 

i think that is good there is another thread in this same section for fuel additives and those guys are talking about using bio as a additive and the said 5% there also they say its good lubercation for the fuel system
