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 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 have a 2010 F150 Supercrew 5.4 Lariat that just turned 100,000 miles that is losing fuel mileage all of a sudden... Over the years I'd get 16-17 mpg city and 18/19 highway(best I ever got was 20 mpg on a trip from New Orleans to Houston with cruise set on 65 all the way and no stops) always checked- tank vs miles, not on dash, and with every tank... I've changed all the plugs recently, did the BG Induction Service and BG Transmission service, K&N filter cleaned and recharged, about to do the MAP sensor cleaning also... I've dropped to 15-15.5 miles for the last two tanks...
Truck runs fine but maybe it's just me seems slightly sluggish when driving and accelerate to speed up quickly. Idles fine etc... I've just ordered a scanner for the computer, not that I have any codes YET...but I'm just trying to figure this out to get back to my normal mileage... Again no codes but what about the 02 sensors, they've never been changed... any other tweaks you knowledgeable folks can think of? Also ran Seafoam through the last two tanks... I pull a trailer from time to time... but not for a while... can the transmission get stuck in a lower setting since I'm told they "adjust" and need a few hundred miles to adjust back to non hauling?
I just bought a 2010 corolla xrs. I'm wondering what type of fuel it actually requires. The manual said 87+ octane but everywhere that I read online is saying premium is the way to go for max performance. Is this true??

View 14 RepliesSo I have had my Platinum for a year now and really love it but there are two things that drive me nuts. First is the range of the romote start, which is the factory installed version. There is no range you pretty much have to right next to the truck for it to work so what is the point? Any way to increase the range?
Second is the audio system, I have the in-dash NAV/Sync system. I use my iPod pretty much all the time. I have it hooked up via USB. Now sometimes when I am listeng to it while driving the turn off the truck do something get back in and stert the truck the iPod does not play, I have to go to the NAV screen and push the USB icon and then it will start to play, other time I just start the truck and it play automatically. I have my system to play automatically but that is not always the case.
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 11 RepliesMy 2014 f250 4x4 crew cab with 6.2l gasser only gets about 7.5-8 mpg at 65 mph while pulling my 27' bumper pull travel trailer. I know that thing is basically a wall trapping the air but is there anything I can do to gain a couple mpg more? I can average about 15 mpg at 65 mph without the trailer on the highway.
View 14 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 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 had my the tires on my 2009 Prius rotated a while back. My car has 36,000 miles on it all on the original tires. It seems like my mileage dropped a bit since doing that. There are so many variables in mileage though, it is hard for me to pin it down to that. Could tire rotation affect my mileage?
View 4 RepliesI was told by the salesman this can use regular gas. Opinions?
View 11 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'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.
So, my 2005 Gen II Prius went for a scheduled service on Wednesday, 70k miles, Toyota main dealer. They called and said it needed new front brake pads and disks, I was surprised but gave the go ahead. There would occasionally have been a mild squealing sound from the brakes at very low speed so I accepted the pads might need replacing, I was surprised the disks needed replacing but it hard to argue about brakes, especially as I only have the car a year (I'm the second owner and it has a full Toyota service history). It had a "major" service, new spark plugs, new front brake pads and disks.
Since collecting it I've noticed that the engine seems to kick in more often and needs higher revs. The fuel consumption seems higher, normally mid 50's MPG (imperial gallon) now 35MPG. However it hasn't been driven many miles since its been serviced so its a low distance for calculating MPG. I've also noticed that the car seems to slow more quickly without applying the brakes, a regularly driven hill that I coast down at 48kph now only gives 35kph. Also, if I drive on a flat road for a mile or 2 and coast to a stop the front brake disks feel VERY hot, way too hot to touch, drivers side more so that passenger side.
