my tires are also a bit lower tread then last run so that may help me with rolling resistance i suppose. im not usually a gambling man but i think the diesel can do it
OEM eco tires for my CTD. i only have 18k hard miles on them.After all of your evidence, he still doesn't believe you!? What size tires do you have? Reason I ask is I have a LTZ RS, therefore, low profile tires inflated @ 41 lbs cold. Not sure about the diesel. Increasing your tire pressure could help rolling resistance.
see 60 i this would be a breeze but as you said 67.3 again is a hard number to hit, repeatable but if i miss the mark 65 mpg i lose 100 lol. now from florida to SC is very flat so not a lot of resistance there. i may also flush my trans before i do a run since im at 20k and im sure the GM oil is at end of its life.My best is 77.5 for 25 miles, but that was on a very specific stretch of PA turnpike with some downhill mixed in. On flat ground at 62 MPH, 60 MPG is definitely doable in ideal conditions, but 67 seems like a bit of a stretch for a full tank or a long run.
thats the thing i know the car is capable of it and not a over exaggeration. he has been working on cars for ages and never seen close to that number so i can believe the sceptisisum. not many vehicles can do what our CTD does. im not a betting man but im sure i can do 60 no problemersonally I don't bet so that tactic wouldn't work on me. If he won't take your word for something even with proof then it's up to him to disprove your word. If you made a mistake in your calculations that's one thing, we all make mistakes, but to accuse you of lying! Providing the proof and showing him the results should prove that your word is good and you are a man of integrity. To me that's worth more than the $100.
My cursing speed is usually pretty high, because the driver ahead of me is probably driving like my grammy when I need to get somewhere. This is good for fuel economy though. :biggrin:told him its all in the drive habits and the cursing speed.
What's the max sidewall pressure? Pump it up!if i pump to lets say 2 psi over factory ( i ran stock on ohio trip) keep the car as empty as i can and keep it at 55mph im sure i can come close but not sure if 100% chance i hit 67.3
Then why bet that you can match your all-time best? That's like betting an Olympic athlete can beat his record on any given attempt. See if he'll take the bet for a slightly lower number. Because right now I'd say your chances are under 50/50 to match all-time best.im not a betting man but im sure i can do 60 no problem
That's an easy one to address. Just fill it to the rim. It doesn't hurt anything on our diesels. I've been regularly doing that for years now with no issues. The only thing is that it takes about 10 minutes to get that last 3 gallons in.One of the factors I'd worry about is what to use to determine when your tank is full. If the pump you use to re-fill clicks off at a slightly higher or lower point, that's going to make a huge difference in the calculations. I'm not sure as your friend will believe the DIC. For a 850 mile run, each 0.13 Gal error is 1 MPG result.
umm i did it with a 100% bone stock CTD i bought at work with 0 miles...the only stepps i took was all driver and route basedBrad Herr is getting that kind of mileage, but he took steps to make it happen ( and be more reliable)...
I got my 77.5 mpg record with a fully stock vehicle.umm i did it with a 100% bone stock CTD i bought at work with 0 miles...the only stepps i took was all driver and route based
Drivers weight makes a huge difference. I loss.I got my 77.5 mpg record with a fully stock vehicle.
on flat highway at set speed not as much as youd think but when trying 1100 miles out of a tank every bit of weight lost helps. every 100 lbs lost is like 10hp if i rememberDrivers weight makes a huge difference. I loss.
