I was in the middle of nowhere and had to fill up with LSD. Will this hurt the 6.7 or is it ok as long as I run ULSD on my next tank?

 

I used about 10 gallons of LSD once to get the the next ULSD station. If I was you, I'd start mixing in ULSD at around 3/4 tank and keep doing it 3-4 times.

Don't worry too much though, LSD is required to be a maximum of 500 ppm, but does not have a minimum so you may have gotten ULSD type levels of sulfur. Some stations get ULSD and never change the sticker.

 

Ive filled up with LSD about 100 gallons at once. Wont hurt the truck.

IT will go into regen alot more and waste more gas and feel like a dawg from the regen since the regen will take longer and more of them to burn it off. Never threw a light or catilysit message.

 

ok ULSD it is next time. I don't think I saw less than 14 mpg and most of the way it was up to 19mpg. Drove about 275 miles on it so. How often will it go into regen mode?Should I mix anything i..e... Additives to the fuel.

 

In a emergency situation LSD is ok.

I have seen ulsd screw up more 5.9s then lsd screw up 6.7s. I know alot of people that have lost there injectors from the ulsd.

 

By mistake on my first work trip with the truck I filled the factory tank with LSD.
Never made a difference in the regen on the truck. However, it netted the best mileage I have had. 17 and a bit on the highway. I had already used the LSD when it came time to hook up a load so no mpg for towing.

I have used lsd for 90% of the miles on my truck and the only problems it gave me was better milage and power.
