We just came back from a trip to Texas and were getting 10mpg with the Cat 330HP @ 60mph. Just have to slow down which I think more people are doing.

What exactly is acetone susposed to do to the fuel? Acetone is a solvent, won't that break down the diesel and cause a loss of lubricity?

Sarge </div></BLOCKQUOTE> Acetone was used in drag racing to ad oxygen to the fuel. It was outlawed when they found out that when it burned it gave off a deadly gas. So witch is better good milage or long life.

jwine: with such limited info that is a hard question to answer. One way to know for sure is to look for a large DPF instead of a conventional muffler. ED

jwine, most likely your setup is a pre-emission engine. I believe all '07 model year Winnebago's/Itasca's were built with '06 engines.

Call FL (1-800-FTL HELP) and give them the last 6 digits of your VIN. They will verify which engine you have.

Also, all engines manufactured after 01-01-07 should be labeled 'USE ULSD ONLY' both on the dash and at your fuel fill spouts.

My 07 WB Journey has an 06 engine in the 07 FL chassis. No worries about trips to Mexico where ULSD is not available.

Best Regards!

PL KIDS.....I don't have a CAT, but have the 400 Cummins in a 36'. I would think that our mileage should be similar. Are you checking your mileage by doing the actual math of gallons into miles and are you averaging at least 3 or 4 tanks. With the large tanks in diesel motor homes, unlevel fuel staions and different delivery speeds it's easy to overfill or under fill them.

You need to do some averaging to get a good figure. My 400 ISL is averaging 8.3. If your doing all of the above and your numbers are accurate, you might have some issues that need correction like a turbo or ECM flash.

Historlic,


We did not have the toad on this trip. May just start leaving it at home more and just walk.

Re ECM flash - the ECM takes 145,000 miles before one gets an accurate reading because of what is called First Fill Effect

This a graph depicting effect:



This shows it using a 200 gallon tank



I've cut it short but I think one can get the idea.
