Huge MPG drop. Not injectors!?
03 Cummins. In the last few weeks I have dropped down to a measly 8MPG. Truck has Edge on Lvl2, Amsoil Air Filter (blown out very recently), OFG not too long ago and a fuel filter only 12,000km ago with the next one due this weekend.
I was towing a light load, only 6k pounds. Usually I get at least 16MPG towing this. I tow this trailer on the exact same route at least twice a month.
Injector return test is only 100ml/minute. Which tells me its not injectors leaking. Truck seems to have power, but seems a tad sluggish above 2k with a load. Almost like it wont rev up enough.
There are no fuel leaks. Ran it for 20 minutes in same spot and let it sit in the garage overnight. No leaks.
I am up for ANY and all suggestions. Thanks guys. Have to drive 4000km in 3 weeks and want to get this solved somehow.
