Greg - What do you suggest with my 6.0 PS Excursion? Do you think diesel additives will prevent problems down the road??
I always look for high-volume diesel fuel stations for my PS fuel and change the FF's every 15k and drain the fuel/water separator every 5k.
I'm not typicaly a big "snake oil" believer, but a cetane enhancer
does work... I've used Power Services and had good results(including 1.5mpg increase).. I highly recomend the Motorcraft fuel additive in your truck though(PS wont hurt, Stanadyne and Raycore are also excellent).. We have seen really good results using it to reduce carbon in the intake and EGR too(but with the new fuel and not idling excessively, it shouldnt be too bad anyhow).. Its about $7 per bottle(that treats 120gal), split that $7 among 3 tanks and it pays for itself easily in fuel economy if you get the same results I did.. Either way its a simple added precaution that will help to keep the engine clean and injectors lubricated.. Good job on the fuel filters
, thats something allot of people neglect, then they end up with failing injectors
and call the product junk.. Also, what year is your truck? If its an '05 or '06 it has an hour meter on the odometer, make sure you change your oil with the hrs(200max) in mind too(big probelm with fleets) although you shouldnt get there before you reach 3-5,000 for the change.. Keep up with the maintenance and you should be good, and try that additive to see what your results are(I bet you see a difference in fuel economy, noise, and maybe performance).. Let me know if you do have any issues though and I'll see if I cant help, I know the dealers in your area pretty well..
