We run Bio Fuel and "Not to be Called Bio Fuel" Sustainable / renewable fuel we buy at COSTCO and Conoco Stations.
They have better lubrication qualities, maybe feel a little less, barely noticeable power and MPG loss. Used to be 50 cents a gallon cheaper, but if lucky now 5 cents a gallon cheaper.
Runs great, passed smog test by a wide margin.
We avoid cheap DEF.
We buy Peak Blue DEF at Walmart and COSTCO. Usually half the price we find it at Travel stops.
Hard to tell power loss, may be regen cycles mistaken for alternate fuel.
Diesel is $5.09 here. Elections have consequences.
