Winter 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 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 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 RepliesI used to get really good mileage on my 12.5 mile commute, if I didn't reach 50 miles per gallon, I considered it a poor commute. But over the last several hundred miles, I have only averaged about 45 miles per gallon - sometimes I'm not even reaching 40 mpg. I checked my tires, they are fine. I also notice that the gasoline engine is running a lot. I'll be at a stop sign, and the battery is nearly full, but the gas engine is running.
View 19 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 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 just recently bought a 96 XLT 4WD Aerostar. It's got about 158,000 miles on it. It's got a few problems I wanted to ask about.
1. When I'm on the highway, once I reach about 82 or 83mph the transmission seems to slip into neutral. Does fine around the city and every other speed on the highway but once I pass 82mph it slips and revs really high. Could it be the torque converter?
2. Clicking while turning sharp and reversing while turning. I figure it probably needs new cv joints?
3. The gas mileage seems terrible. I still have my Ford Econoline 250 and that seems to be getting better gas mileage. What might cause the mpg to be as bad as 12mpg on the highway?
4. The speedometer goes nuts after about 40mph. Is that an easy fix?
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.
AC recharge seemed to be when problem started. But... If I do NOT run the AC unit and drive it with VENT open there seems to be no smell. When I run the AC the smell appears. Since the AC system is supposed to be(I think) a closed under pressure system why would I get a gas smell ONLY when the AC is running? Starting /stopping it gets a bit worse. Baffled here but that's nothing new...

put a new radiator in my truck, as the original one finally had a small crack.. (I've kept it, since it is brass or copper!)
I put a new 192 T-stat in there too, (OEM temp)
but, now it seems that the van is running hotter than it did before!
when I had the original rad in there, it would never get above the R in the Normal word... now it runs at about M (high middle)
Also, when I tryed to burp it, I'd top it off, but then it would put the extra in the overflow tank, and only stays full up to the very bottom of the filler neck.
this is a plastic radiator... is that what the difference is?
I used to be able to top off the old tank, and it would be right at the top whenever I opened the cap... not so with this one>?
wondering if I should go down to like a 180 degree t-stat? gauge still stays normal - but if it's correct, it's about 50 degress difference.
Wondering what could cause an increase in fuel economy. My GTI has been running at 29 +/- MPG since the day I bought it, but no higher than 30. I took it out for a ride on Sunday after I changed the front brakes Saturday. The dash tells me it's running at 34. So I filled it up and manually clocked it on a 50 mile trip. I refilled at the exact same pump - just to remove any error. And what I calculated is that the computer is right.
There is no loss of power. However, I've been fighting intermittent misfires on cyl #1 and #2. the misfire on #1 has all but gone away after finding out the coil wasn't sitting right and the spark had loosened up. I've tracked #2 down to either the injector or carbon. I'll be taking care of that next weekend.
We gave the Prius a good workout in the rain for the first time today. Central Florida has been having serious amounts of heavy rain, creating water covered roads in our area. Normally the digital fuel mileage display shows around 55 MPG for most of our driving. However today it dropped to the upper forties very quickly.
We were running the wipers on continuous (low and med speeds), the AC (defrost) was running to keep the condensation off the windows, and the headlights were on. I wonder if the extra resistance of the water on the road also had an effect on the fuel mileage.
Even though we hit some fairly deep water and created large amounts of splash, the car tracked straight, the brakes worked well, and the power was totally uninterrupted. Other than the poor fuel milage we were impressed.
1991 aerostar 4.0 ... My van was running well til last week.it allegedly has 77000 miles on it. It started running really rough within a 50 mile period. I've quit driving it til I am sure. I am not harming it. I put a vacuum gauge on it. It wildly fluctuates between 3 and 7 pounds at idle. I've tried plugging the four vacuum lines one at a time to eliminate the accessories as the problem.the check engine light is off and my scan tool shows no codes.i unhooked the exhaust at the manifolds to make sure the cats aren't clogged.it doesn't have egr. There's no water in the oil or bubbles in the radiator.i have a compression tester but id like to avoid trying to get to the plugs unless necessary.
View 5 RepliesOk I read about replacing a bad or ailing 12v battery (mine was original - 2007 - and resting at 10.1v) and an increase in mpg's. But I didnt expect this kind of increase!
I bought the car 9-14-12 and had been driving it very hypermilishly...lol...and getting 48mpg average.
What is the procedure for replacing the fan clutch on the water pump? Mine has a slight wobble when running and I started to pull everything apart but got stuck when I couldn't see how the fan and clutch disconnects from the water pump. It's a '94 4 liter XL extd body...
