[Thread Backward] Re: Mileage/Power Improvement After BreaMsg # 4936 of 8004 on Powerstroke Diesel Conference (1)To: Headhunter, From: Dave Time: Sunday 01-25-98, 01:45 pm Ray, Try reading the damn post before shooting your mouth off with your poetic waxings! I'm making direct comparisons between vehicles, not saying that it should get the same mileage as a moped! If you're so damned in love with your truck, go outside and hump it, and stop wasting everyone's time with reading your drivel - I'm here asking for help, not erotica..... I've driven 5 other Powerstrokes, and the worst of those got 18.4, with the others all over 19. And I haven't seen much of any seasonal variance in mileage on my IDI. Given a conservative median of 19, that leaves me down by 15%, which is rather much for my tastes. Again, this is poored than my IDI, which consistently runs upper 16s, with a high of 17.3. I've heard that DI should yield about 20% over IDI, so this definitely has my eyebrows raised. To the other person who's responded thus far: I can't see snap idle stuff affecting highway mileage and top end power. When did the EPA regs affecting diesels last change? I know that something occured on 1/1/95, but am not aware of anything more recent.

Sadly, it seems to both have less power --and get poorer mileage than my '94 F250 SC IDI --factory turbodiesel (w/ aftermarket turbine housing --& exhaust), 4x4, E4OD, 4.10. -- --On other PSDs that I've driven, when tromping from --a standing start, you can see the engine rev to the --torque converter's stall speed, and then, over a --half second or so, feel the boost come on, via the --seat of your pants, with a nice satisfying rush. --This one is much less distinguished in its coming --onto the boost. -- --I don't hear any kind of rushing air sound, so I --don't think that the exhaust butterfly is sticking --shut. -- --At about 175 miles, took it out solo, with an empty --bed, for about 200 miles, out and back, on terrain --that gains elevation (1-2000 feet) fairly smoothly --over the hundred mile radius, starting pretty near --sea level.
