B5 bio
 

Hello,

using B5 bio for the first time and it seems as tho my MPG is off about 1 or 2 MPG. my question is this, will bio cause for a lowering of MPG? has any one noticed less?

thanks,

There may be an issue with the bio-diesel , B5 is 5% , average additive is about 3% .
Bio-diesel has around 15% less BTUs , but more centane .
There is not enough bio in B5 to affect millage that can be measured .
