what kind of mpg do you get?

Nahhh,, they pay!
Compare when your new rig gets there! Even though, it will still be a curvy nose, so should be better I think.
D/H back if I keep it under 70mph is over 8MPG though, which I am very happy with

Huge differences right there...

S60 DD 14L, EGR electronic delete. I am still running the VNT, no blanket. 3.42 gears, LP22.5. One set of virgins used 720's to about 10/32 and a set of recap michelins at 9/32. (they should be getting replaced with 710's this fall), 13 spd tranny, 2003 Great dane reefer. No skirting, LP22.5 recaps on the trailer. If I do anything to the trailer, I am looking at the full UT6 package.

Currently right now, this is my ifta report for July and Aug to last Friday. Realistically, I consider it more to be around 7.5 to 7.7. Considering just this past spring I was in the mid to upper 5's. I'd say I had a lot of mechanical issues to work through. Room for improvement? yeah, there is. right now though, I am tickled to see a 2 mpg improvement.
CAC, Wiring harness, power divider. All three of those combined sucked a lot of my mileage. The biggest and most consistent improvement came after the power divider replacement last month.

I now want to replace my air filter since it's now a year old. Showing about 8-10" of vacuum on the gage all the time.

 

why is everybody that runs the legal speed limit is a supertrucker with no "time managment". :smt102

 

Haven't figured that out yet either. I am only interested in information. I don't care how fast or slow another person drives or how often they stop. I don't see where it is my concern. Some days I drive slow and some days it works out that I drive a little faster.

 

I have t660, is 09 with 525isx 1850 torgue,18 speed, 3.36 gear,260 wheelbase,86 inche sleeper,full fairing. turbo wing,tire sized 11 r 22.5. I used to run it around 65 mph,my rpm exactly 1300 rpm,I get 7.2 to 7.8. My weight alway under 25,000. Now I run it around 70-85mph,I get 5.9 to 6.2, yeah running fast drop my fuel mileage,but why I choose to run fast?i get home spend time with my wife n kid,unload n reload n doing another trip,running slow,I can't do all that,saving 50 to 80 a gallon,like $320. And lose time with family,is worth it?

 

nice,...very nice...

I replace my intake filter 3 times a year. I have lowered the front-end of the truck for better air flow, this has helped, but don't know by how much. I also have M710's on drives / R283's steers. I use crossfires and keep them pumped up to 120psi and let them crown a bit. Also, I use 5th wheel slider lube on my 5th wheel like mad. Every trailer. I go thru a bottle every week or so. Grease is too messy. I have been looking at wheel covers and/or air-tabs lately, but I drive slow. Don't know if they will help much.

The downside of my timing shift is that I go up hills 1 lower gear than I used to. I keep boost below 10 most of the time as well, putting me in the slow lane, even when empty. I don't mind tho, I drive stress-free. No one ever gets in my way.

I have completely traded away driving fast and working my tail off for the less stressful, less miles, higher profit margin way of making my living. I love it, and my wife does too. I sleep good while she is driving because I know the truck is not moving fast. We have been driving this way for 4 years now, and hate going faster than 60. We let it roll the speed-limit downhills, especially out west, to help with fuel, but otherwise just poke along. We take lots of back-routes because the interstate has little advantage for us. This shaves a lot of time and miles off our runs because of a more direct path. There are many small towns that we go thru where the sheriff will wave at us, and we wave back because we travel thru them so often. Last year we averaged 4502 miles weekly as a team and had 11 weeks off throughout the year. Still we managed to rake in 130k net after all expenses. This year, we have no more truck payments, and now, much higher fuel mileage, so I will just have to see where we end up, but its looking really good so far. A few more months will reveal how much further we are ahead.

 

If you guys want to pick up 2/10ths to 4/10ths mpg, get rid of the paper filters and use either a washable Fleet Air Filter like I use or even a KN Filter than I heard similar results from. You will also feel a little better throttle response from freer flowing filters that I have 2 filters that I rotate with a clean one every 3 months.

As far as tire pressures in my Michelin x-one energys, I start at 125 psi cold and I highly recommend tire sensors that is a good investment that will be paid for by preventing the first roadside service call for a tire.

 

I don't know about the Fleet Air, but the K&N only filters about 80-90% of the dirt out. I would rather have a little bit more restriction.

 

Agreed!,.. I tried one,...yes, used it properly, and oiled it,...didn't like my oil samples. Didn't have any improvement. I suppose it would help those drivers that suck 30+ pounds of boost all day, but I don't have heavy air-flow requirements.

 

I check my tires daily, and plug/ repair them myself. I also have the tools to swap tires around. Steer and drives same rims,...even if i were to loose a steer (not likely), i would swap it to rear and get myself to a tire shop.

my roadside/parking lot repairs have included thus far,...

tire plugging/patching.
Turbocharger bypass.
rear axle alignment.
tie-rod adjustment.
leveling valve bypasses.
repair of corroded engine wiring harness.
temporary headlight re-wiring.
Alternator replacement
starter wiring repair.
wheel bearing replacement.
blown compressor line repair.
drive-belt replacement.
re-mounting of a fuel tank (it full of fuel) that dropped (strap broke).
A/c recharge, valve replacement.
APU a/c compressor replacement.
APU belt replacement.
front AND rear air-bag replacement.


the list goes on...

I will call a TAXI and get a ride somewhere to get parts before I will call ANY shop for assistance.
