Ooops... I forgot the five-o envy.

 

Yep I am sure jealous of the eco, I mean its not like having 400 hp and 800ft-lbs of torque and getting 20mpg on the highway in my 2011 f250 can ever fill the hole left by not owning a tt v6.

 

Strange post, are we at www.powerstroke.org? what does a F-250 diesel have to do with 1/2 ton gassers? Either way... keep us posted on your regens and the MPG you get during those & not being able to shut the truck down until one is finished or risk pluggin the DPF, the cost of your fuel filters every 10,000 miles, your DEF fill-ups and issues with that system, The cost of filling the fuel tank with more expensive fuel, waiting for those lovely glow plugs to warm up before you can start the engine (it's actually gotten a lot faster since the 6.4L), and lets not forget the 15 quart oil changes
I've done the diesel thing (08 F-250 6.4L) and will NEVER go back. I will buy a smaller travel trailer to avoid another modern day (DPF and beyond) diesel.

 

He was acting like everyone was jealous of the eco, or couldn't afford one which is not the case.
Regen drops MPG by 1mpg when it hits a cycle. A fuel filter is 90 bucks, ya that's expensive but if I couldn't afford it I wouldn't have bought it. DEF is 11$ for 5 gallons and last around 3500 miles while towing and longer than that just driving so that's not to bad. I have yet to have to wait on a glow plug, its summer and 100+ every day, however I have remote start and start the truck from the house so there is no waiting. Its 13 quarts of oil btw and again if I couldn't afford the oil I wouldn't have bought the truck. I will however report that I love the additional room inside the huge cab of the supercrew f-250, the power is phenomenal and blows away any f-150 engine, and it sounds amazing. When the warranty expires in a few years I will be doing a straight exhaust and EGR and urea delete, so I won't have to mess with that anymore.

BTW anyone else notice how defensive most of these egoboost guys are? I make one post about how I am not jealous of the engine and I get bashed for buying a truck that I wanted and that in my opinion is superior. Even though on several occasions I have said that I think the eco is a great motor, it just wasn't right for me.

 

^sounds good, I was just messing with ya.

 

 

Re-read, o diesel wan kanobi. The jist of my post was that there are some on here spouting on the EcoBoost OR the 6.2L don't even own one, but they are directing people like they are writing the check. The MAYBE reference for the envy was not stating people WERE envious, but matter of a question. That funny squiggle at the end, one of theses ? Is a question mark. Now, I'll get back up from bowing down to you and you almighty diesel.

 

Amen.

 

I am not really anti Eco boost, I just can't do the v6 thing. Had they just done like a 4.5 4.8 or 5.0 ecoboost v8 i would probably be more inclined to try one provided it was available with the 36 gal tank. Until then i am stick'n with the 6.2Ls. I have one in my rapptor and swapping it for another 6.2 in a platinum this week.

 

Cc1999,
I know the Raptor has the 3.73 and some serious meats, but what kind of mpg's have you been pulling with the 6.2L? Let me know the type of driving - city, highway, interstate, etc.
Thanks,
Smoke

 

If you get a moment, could you post the facts or proof where you saw/heard/read this information?

And 6-8 lbs of boost is hardly "compressing and forcing". Keep in mind Ford's 5.4L could handle what, 550 rwhp on stock internals? and some Mitsus are pushing 600hp @ 35 lbs of boost before breaking.

 

I don't see anyone directing people like they are writing the check, I see people giving personal opinions on what they believe which is what happens during a discussion. You were also implying that the people giving their opinions cant afford one of the trucks when you said which I don't see as a valid argument of why they shouldn't have an opinion on the matter or be able to share it. Also that's fine you can go ahead and get off your knees I am done with you anyway.

 

actually I think my raptor has 4.10s in it. The Platinum has the 3.73s. Mileage is by know means the Raptors strong suit. Its avg is 12 I have got it up 14 babying it, I have got as low as 8 pulling a 5000 pound trailer up into the mountains. Keep in mind the Raptor has no air spoilers, is extra wide body, extra tall, with 10 ply 35" offroad tires. That platinum 6.2 should get what they claim, about 2mpgs better then the Raptor 6.2. I drive pretty moderate, to mild lead foot. I do cruise around 80-85 on the interstates when possible. I do nail it once in a while to pass or get up to speed on on ramps and such. Nothing crazy. My 6.0 Chevy max had less power and got about the same mileage, maybe slighty better at 13.?? vs 12.?? same mileage pulling a trailer yet the Raptor 6.2 pulls the trailer much better, with more power. The difference in the 6.2 ford and the 6.0 Chevy is found mostly when trying to pass with trailer.

 

2011 4X4 4-door Lariat with 3.73s got 17.2 last weekend. 70% highway, 30% city.
