Been 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 RepliesHave 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 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.
How much do any of you increase your tire pressure while towing?
View 7 RepliesNoticed a drop-off in mileage for there v-10 excursions after 200k? My 2002 ex used to be getting 10-12 hauling a 9k lb work trailer and 14-16 on the highway. After i rolled over 200k though I am down to 8.4-9.3 mpg. My only ideas is to run seafoam through the engine and get the injectors cleaned.
View 3 RepliesThe stock 265/75/16 tires need to be replaced and I was considering swapping 285's on the stock wheels. Will I notice an increase in fuel consumption? I realize that calculating mpg will need to be adjusted due to larger tires since the speedometer will be slightly off.
View 14 RepliesFor the past two years I've noticed a decrease in fuel economy and recently noticed that the truck did not "feel" as if it had the same power especially when towing. Checking all the usual suspects with the engine turned up nothing and the transmission wasn't showing any signs of problems other than an occasional delay going into reverse. But it had been doing that for years and so I just ignored it.
Recently the torque converter started acting up and had some other occasional shifting delays and so decided to put the vehicle in the shop. The electronics all checked out and so a HD rebuild kit was ordered. The truck was finished this morning. Just barely pressing the accelerator makes the vehicle instantly start forward with noticeable zip. Plenty of power at all speeds, the engine now feels like new.
I suspect the main culprit was the torque converter. It wasn't enough to notice in excessive rpms nor heat (at least according to the instrument gauge) but the loss is noticeable in hindsight when compared to the repaired system. Over the next few weeks I'll get some mileage numbers and will know for sure whether I've found the sole cause of my power problems but I am sure that I've made a fairly large step in solving them.
What 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.
I want to lower my 2014 FX2 supercrew 2/4. Can't seem to find any drop spindles for it. What are you using to drop your trucks. I don't want to change the driving or handling of the truck any more than necessary.
View 14 Replieshow would I go about lowering my truck in the rear a few inches cheaply? There isnt much out there that I can find.
View 7 RepliesWhat besides a 4" exhaust can I do to lower EGT? When I tow with my tow tune the EGT gets high on long steep pulls. Would like to be able to use it with the tune because there is more power and it pulls nicer, but I want to lower my EGT. I have a 4" flo pro system coming. What else can I do? Would a new intercooler make much of a difference? Already have an S&B cold intake and Banks Hi Ram.
View 14 RepliesI'm fresh out of the perverbial womb to this place and only about a toddler when it comes to my truck. However I do want to learn! I just recently invested in an 02 XLT F350 7.3L. I'm in love with the truck except the leaning forward aspect. I am debating on leveling it via lowering the rear. Any thoughts? Things I need consider that will happen if I do? How would you do it? Would you do this over raising the front? I've heard raising the front can mess with the suspension geometry and that's not a good thing to do!
View 10 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?
