Is that the norm? I have 12k on her now and man does she pull hard all of a sudden. If I give her 1/2 to 3/4 throttle at around 10-15mph, she just rips down the road chirping the tires into 2nd and then they keep trying to break free up until around 40-50mph.

I don't know if we get a winter blend in the San Francisco area on Diesel, I know Gasoline is different in winter due to smog. Maybe we do get a winter blend from Nov-Feb and now they are coming back to summer fuel?

 

Yep, that's normal.

 

The fuel is normal, or break in period? I am guessing fuel, cuz I just filled up and my MPG jumped up 5.4 more than it was all winter ! I think they cut off the winter fuel at the first of march. Hope it stays this way!!!

 

Can anyone confirm or deny that there is such a thing is winter fuel and what is the difference between winter and summer fuel? Just a newb tryin' to learn!

 

No pro but, I've give it a shot. #2 Fuel [summer fuel] has a higher gel point than #1 fuel [kerosene]. They blend the two together to lower the gel point. I use to haul fuel into the Kenworth plant in Chillicothe-straight #2. Then they order a load of #1 fuel oil [kerosene]. I asked why & was told that the EPA was said the emissions [fumes] were too high in the plant or dino room. Kerosene burns cleaner. Later I took in a load of #2 & asked again. They told me the engines could not develop the advertised horse power. #2 fuel has a higher cetane rating than #1. Hope you can make sense of what I'm trying to say.

 

I doubt they use winter fuel in SFO due to never getting below freezing for extened periods. But I have noticed my overhead display will read the same mpg on my way to work in the morning when it's in the 30's to 40's, then on the way home when it is in the 70's my milage will jump up about .5-1.0 mpg. So if it's been warmer than usual that might be the milage gain you are seeing. That's been my observation.

 

If the winter blend burns cleaner then it makes sense to use it in Cali during winter.

 

what about the break in, is it really ture that they are not at there full potential till after you tow or haul something heave or have like 15k mi on it cause my truck just broke 1000 and it is slow as hell

 

can anyone really confirm the more power/ working to full potential after 15k mi or pulling something really heavy

 

Mine is slow.

 

thats what i am saying there are 4cyl family sedans faster then my truck! thats why i want to know if it really does get better or did i get a lemon

 

Hook 20,000 lbs behind that 4 cyl and see who's faster or can even move.

 

i only got 120 miles on my 06 and it feels real good

 

"Feels real good"

but my question is i hear everyone on here that at 1/2 throttle its spinning the tires, there is no way mine is going to do that!

let me give a example we just bought a toy hauler, when were were driving it home over a little grade nothing extraordinary, my truck pulled it just fine but it was deff noticable that it was there, the trailer only weighs about 6000? from what i have read people have pulled 25k with no problem, i just do not see my truck doing that.

now here is what iam thinking some people on this forum are full of you know what... and thats how there truck pulls 25k with ease!

 

Ya I agree with you, i tow a toy hauler that tips the scale loaded 9526 lbs.In Colorado yes it pulls good but cant imagine 12500 plus.Oh ya 2006 ctd 30, magna flow and air box mod.
