wmo & dino
 

can wmo be blended w/dino and eliminate the need to preheat tank or will it not stay blended.

This can be done. Many folks have done this with success, in warm climates it works best. There are some folks that will tell you this will cause issues.

The debate lives on on many other forums. WVO and diesel mix very well. Some folks go as far as doing a mix of 80%WVO 15% diesel & 5% regular unleaded gas Or RUG.
