Eco-diesel Alert

6 speed so 55mph its good, 16-19.  Work trailers around 14-15.  To Idaho mnts with 9000lb toyhauler at 72mph was 11mpg.  Pulled Vantage at 72 in 6 gear cruise control 1250 egt's.  100hp tune. 36psi boost, coolant 215degrees.  Hand calc.  Lie meter claims 14mpg.

What axle gears?  Seams like it should be better.

I haul a 11k TT and hand calc 17 in my 06 auto doing 65 to 70 to Montana and back once a year.
I tow in level 2 on the EFI switch, about 50hp.

373 I think.  My 05 auto did better.  Its a low geared beast.  RPM around 2300 at 73mph.  This 6 speed likes 60mph best mpg.  I will say wind is big factor with ToyHaulers.  We had lot weight in bed but who doesn't.  I was running EFI from Anarchy level 3 stage 2 tunes.  It wants more turbo but I don't need it.  Think truck has 50-90hp injectors but I cannot verify without pulling n flow testing them.  Yes Jackelope, I know and agree.  I distracted forgot mention Airdog 165G fuel filter and water sep. kit on truck.  Dirty FUEL is #1 danger to these diesels!!!  Put Filters on em everyone!!!

1 ton? Could be 410's  I have 373 as well, 3/4 ton.

Amazon has CAT 2 micron filter kits for $100 or less on most model diesel pickups.
The filters alone are only $25.
VERY cheap insurance.

And don't get DEF in the fuel, not a filter in the world that will save you from what that does.

Last fuel contamination issue we had here. This drained from the fuel filter housing. 6.7L powerstroke.  I’d love to see what is in the tank. She said she got a little DEF splashed into the fuel filler. Really I doubt this is DEF contamination.
Lady declined fixing it and took it home. She’ll be back on the hook.

Its a 2500.  It had many upgrades so hard to know.  Intake manifold, exhaust manifold, exhaust, full double gauges, custom Quadzilla tuning and it ran 42-47psi boost etc. Full suspension from arms to shocks to coils, free spin hubs etc, it scared me as I didn't know if it had modified Tater turbo or ARP studs or Injectors so I turned her down with EFI to be safe.  I really don't know what she has done but someone spent serious $ on it to trade in with 50k miles.  I had to put Valair double disk clutch in it to handle the power.

Could be fuel issue. Acted lil funny. Put in 5 gal diesel from same nozzle it had been filled from and it went bad shortly after.  Maybe container got something dumped in it.
And fuel filter was due to be changed.

Love my Ol cummins.  Can see and name every major part under hood.  No emisions. 400hp or 500 flip of a switch.  Just saying old isn't bad... Prices they are charging now man o man.

What's Your fuel mileage on that dinosaur?

My bone stock 2wd dually gets 18-20 on the highway. As much weight as I can pack below the cab. I have slightly larger tires that keeps the rpms down to 1800 at 68 ish mph. Wont replace my 03 0r 05 just rebuild them.

Fuel contamination will ruin your pump too and it would be super expensive to fix also. This has nothing to do with emissions.

No chance of putting DEF anywhere near it tho!

Best investment a guy can make is that 2 micron secondary filter!

What is that dark stuff? I've never seen Def fluid, is it dark?

Did they pull a fuel sample? Usually should be step 1. No sense in fixing anything without at least knowing what’s in the tank.

DEF is clear. That’s not DEF.  Its whatever is in the lady’s fuel tank.
