Have a 1992 F-350 4x4, 429 V8; auto transmission with o/d. I tow a fifth wheeler. Without camper if I stay under 50mph I get 11 mpg; doing almost anything else gets 8 mpg; towing brings it down to 6.5 mpg.How can I increase gas mileage. I drive with a light foot and slow start and stop.
View 17 RepliesBeen doing some research about MPG and towing. Can-Am RV recomends lowering your TT to increase mileage. I'm wondering if I could get lower profile (or just shorter) tires on my rig whether I could increase my mileage because of lowered wind resistance. I've weighed the rig so I know what my per axle weights are. My current tire capacity (Michelin M/S load range E) is way over the posted axle weights on the truck.
View 14 RepliesWinter is over and summer is here. Will running with the AWD module unplugged increase fuel mileage? Will it do any harm to the drivetrain? (Assume matched tires, good alignment and suspension).
Signed, Looking to squeeze a buck anyway I can.
I was wondering if one would experience increased fuel mileage &/or power with the 5.0 by using unleaded premium gas, and if so, how much? I know this is true w/ the 6.2L in the F-250, and was wondering if the same applied to the 5.0?

View 2 RepliesWhen I put on a Flowmaster end muffler on my '99 Venture....will that increase my mileage? I mean does the engine needs the original tail pipe pressure to perform the best mileage?
View 2 RepliesSo in one of the owner's manuals, Lexus states that use of EV mode does NOT increase overall mileage. I was surprised by that. If this is the case why have it? I have been using EV mode after I get off the freeway and drive a couple of miles through our subdivision. I deplete the battery almost completely (2 bars) but make it into the garage. Will this damage the traction battery and should this not improve the mileage. The engine runs in the morning anyway to warm up and the battery charges up then. I am just wondering how others use the EV mode.
View 9 RepliesI'm just curious...if somebody drives a PHV Prius like a regular Prius (not using the 13 mile pure EV mode range), could they theoretically get better gas mileage by staying in the electric part of the hybrid system indicator?
View 19 RepliesI have recently noticed that the ODO meter of the car does not work i.e. it is stuck at the reading (57735 km) it was on when I got the car and does not record/show the increase in mileage. the trip A and B are working perfectly fine. I took the car to the local Toyota dealer but he has no clue what is wrong with it, the guy there suggested that ECU is working fine but the ODO meter is damaged and needs replacement.
I am not sure what the guy at the dealership suggested is correct because what i think is that if ODO gets damaged then the whole speedo meter should mal function.
I am having trouble with my 1999 F350 Ford Powerstroke, Looses power but the motor never quits and also starts up fine, will set and run and warm up on the coldest morningIdles fine, It will hold back sometimes and not increase speed. I can take it out today and it may be fine and tomorrow can't run 2 miles. I was thinking CPS but after reading information I am not sure. What may be causing this issue. I just put a High Pressure oil pump on it could this have anything to do with it. Was not having a problem before the pump was changed. The pickup has 190,000 on it actual miles.
View 7 Replies1999 F350 SD ... Yesterday when goosin it to get on the highway my rig threw up a code quickly and engine temp started to increase. Once temp got in the red, oil pressure got a little figgity. The code was for the ICP(p1212), so I cleaned the plug and made sure coolant and oil were topped. This morning she ran barely over normal temp (stock gauge). This afternoon same thing as yesterday but without the code. When I let off of the accelerator temp goes down. I just got married so I have little funds to throw at a shop.

My car was getting 28/29 mpg when the water pump went. Afterward the work was done the mileage dropped to ~21 mpg. Going back to the place that did the work is not an option. A few months after the work I decided to do a tuneup to fix the mileage. A guy from the parts store came out to show me how to deal with the spark plugs and told me I needed a new valve cover gasket. When I went back to the place that did the work, they agreed I needed a new gasket and would do it for the full price. They also agreed that they had just replaced it when they did the original work. Even I know gaskets don't fail that quickly. So they did a foul job originally. What could they have done to kill the mileage?
what is the best computer chip for a 2011 F-350 to get better gas mileage?
View 4 RepliesWhat kind of mpg increase one would see if they were to increase the tire pressures from recommended (35 F/33 R psi) to max (44 F/ 42 R). Any stats of tracked?
View 1 RepliesI've had my XB 5-speed for nearly a year and 10000 miles. It as been dead on reliable and fun to drive. My gas mileage has varied from 26 to 31 in mixed driving and from 32 to 35 on the highway. I use premium fuel only because I can get it without ethanol. My fuel mileage also increased a couple of mpg due to getting the power robbing ethanol out. True it is probably not enough to offset the extra expense but I like not having the stuff in my car. My only dissatisfactions has been with the transmission gear ratios. They are way to low. This torquy engine could easily do with a ratio that would drop about 500 rpm for more relaxed highway cruising.
As it is, though, my XB will go up any hill or long grade without breathing hard! Another is the instrumentation. I don't mind the center mounted set-up but speedometer and trip meter for mpg ratings are both inaccurate. My speedo reads about 2.5 mph high and the fuel mileage read out has about the same error, also on the high side. I have the stock 16" tires. The clutch has a narrow engagement band and can be difficult to be smooth on. The car is fairly quiet, is comfortable and this years hot, humid summer has shown it has one of the best air conditioners I have ever experienced in a car. I thought it might be an electric unit rather than a belt driven compressor because there is absolutely no perceived drag when the compressor kicks on.
How much do any of you increase your tire pressure while towing?
View 7 Replies96 Ford Explorer, 78,000 miles After about an hour on the highway (60 mph), the vehicle slows and cannot increase in speed. It does this until it slows to less that 20 mph. Pushing on the accelerator increases the rpm, but does not result in an increase in speed. It only does this after an hour or more on the highway (city driving does not cause the problem). No one can diagnose the problem; already took the vehicle to the dealership and a transmission specialist (both said nothing was wrong). Hoping very much to keep this vehicle.
View 6 RepliesI just replaced the vacuum motor that opens and closes the Max Air door as it's diaphram was ruptured. Now it is working correctly, however when I go from normal to max the volume of air coming out the vents doesn't seem to increase. The door hasn't been working for about a year and I didn't realize why. Should the volume increase going to Max or just the air get colder from recirculating? In my Dodge the volume increases consderably. Could there be trash (leaves, things dropped through the defrost vents) partly blocking the air through the evaporator? How do I access to check and clean out? Remove the blower motor?
View 1 RepliesI recently got a 2002 f150 5.4. The fan speed works on 1 & 2, and 4. It does blow on level 3, but it seems to blow at the same cfm as level 2. I'm thinking this can't be right. But, if it was a simple resistor issue, it wouldn't run at all on level 3, right? So, where I should look first.
View 10 Replies2005 Excursion 6.0 with normal bullet proof mods... towing 6000# dual axle enclosed race car trailer.
I've been towing this same package since 2008 all over the eastern half of the US and averaging right around 10MPG.... hand calculated from fill up to fill up. Sometime a bit more on a flat run to Daytona, or a bit less through the mountains... but very close to 10 MPG.
Well the factory trailer tires finally wore out and I replaced them with 8 ply Maxxis M8008 trailer tires...... highly recommended by the camper crowd.
Since then, I've been round trip Baltimore to Pittsburg, and Baltimore to Daytona (total of 2500 miles) and I've been averaging a bit over 12 MPG consistently..... again hand calculated. Same package, same highway speeds.... nothing has changed in my towing style.
Seems almost to good to be true. At this rate the tires will almost pay for themselves by the time they are worn out. Any trailer tires make such a difference ?
I was just curious what the best way to increase initial acceleration from a dead stop is for a 2009 F- 150 XLT with a 5.4 V-8.
