Fuel Additive?
When I had the Foretravel I used this in the fuel, Should I use this in the Prevost??

I do.
Even though we only buy our fuel at Pilot/FJ (high volume), and even though we don’t sit long, and even though we store the bus in a climate controlled – low humidity garage, I don’t want to repeat a problem we had years ago in a SOB RV.
I doubt it is needed. It is not expensive. I don’t think it hurts anything. I only use it in the warm months (we live in TN).

I got the pour spout at WalMart… makes it easy to pour in the Prevost fuel cap.

That’s cool poor spout

I’ve used Biobor at every fill up all year long for years with the Foretravel and current coach and have never had a fuel problem. Maybe just lucky?
I like Les’ spout doo dad. Gonna get me one. The large bottle won’t pour into the tank.

Les,
Pilot/Flying J high volume, Loves is high volume and .10 a gallon off cash price.

I use the Biobor MD formulation in our coach (https://www.amazon.com/s?k=Biobor+md&ref=nb_sb_noss_2 ). We haven’t seen much if any difference in mileage, but our webasto does burn noticeably cleaner since we started using it. We sit quite a bit in the winter, and even in the high AZ desert 🫠I don’t want to have self inflicted problems. I have to pass on our thanks to Rudy…he recommended this particular additive to me several years ago, and it has worked well for us to date.

I’ve used nothing for 29 years except for one year of running snake oil for a test and have never had a problem. I have lived and stored the bus in cold temps and high temps and never added anything to my fuel. Never an issue.
Lucky?

I have a similar spout I got at the local NAPA . It is great for using on gallon jugs of coolant.

Our Walmart had two different sizes of pour spouts. One fits the Biobor size containers and the other fits many/most gallon containers (think PowerCool).

Biobor MD appears to be a diesel fuel stabilizer and anti-gel agent. Biobor JF is an microbiocide.
My problem, years ago on a SOB, was algae. The first RV we bought sat in Hilton Head Island for over a year and developed what I called “black elephant snot”. Shortly thereafter the switch to ultra-low sulfur diesel happened and I got a lot of practice changing fuel filters on a Cummins ISL.

I either got bad fuel (I only stop at truck stops) or had a algae bloom in my Foretravel. It is truly something that you do not want. I had my fuel polished at Cummins Coach Care in Kansas City, MO. You bring your coach in with about a quarter tank of fuel, they add a chemical, then you fill the tank and let it set over night. Then they recirculate the fuel filtering it for about 6 hours. About $400 later you have a clean tank and fuel. So, I do use a Biocide. When I am parked for extended periods. By the way that biocide is nasty stuff. Read the warnings.

Algae is a serious problem, but preventable. Continuous use of the coach is the easiest way to prevent algae. But I suspect most of us do not run the coach regularly so during periods of storage the first thing that should be done is to make sure the tank is full. The less air space the better.
If possible store the coach where temperatures are constant. If the temperatures vary very little the fuel tank is not “breathing” air in and out. As temps go up and down air expands and contracts and as it enters the fuel tank the humidity condenses and with moisture in the tank algae forms.
Once algae is present it is a serious problem so the cheapest and best solution is to keep it out of the tank.
My coach is parked for the summer, just like it is every year. But my tank is full and my garage is well insulated so the temperatures in the garage are going to be a relative constant through the day. Right now the garage is at 65, but by the end of summer it will have risen to 80, but it will take all summer for the temp to rise that much, and during the day the variation in temps from the coolest to warmest and be counted on the fingers of one hand so the tank is not breathing air in and out as it expands and contracts.
If you cannot store a coach in constant temps use an algacide and carry spare fuel filters. Algae if formed, even if killed with an algacide can plug filters. The worst place to store a coach is where humidity is high so if that is where it is stored keep the tank full to minimize the air space.

Has anyone with newer coaches/engines encountered ‘asphlaltenes’ in their fuel and mistaken it for algae?

Hey Les, I checked at our local Walmart super center today and they didn’t have the pour spout you show. I looked it up at Walmart on line and couldn’t find it there either. Do you have any name or number of the item to help me Find it?
Just found it for anyone interested. Just copy below and put in search box at Walmart or Amazon and you’ll go right to it. Walmart is cheaper!

We found them on the top shelf near the gas cans. I walked by them 3 times before they jumped out and almost bit me.
