Prius (2004-09) Fuel :: 2008 Touring - MPG Drops After Oil Change
May 23, 2013
I changed the oil on my 2008 Prius Touring in the weekend. I consulted the manual after the oil was changed. One mistake I made was to use 10W-30 instead 5W-30 recommended. The manual mentioned that it affects MPG with 10W-30. For the 270 miles trip I took right after, my average MPG dropped from ~46 to 45 highway. My short commute driving dropped from ~37 to 34. Comparison are made on the same roads with similar temperature and driving speed. Is that normal? Will it go back up after a while?

I have a 2008 Touring. The air has always been ice cold, even yesterday. On my commute this morning I noticed that the air was not cold at all for the first time ever. The outside temp said it was 77. I changed the temp, turned it off, etc but nothing changed. I just had it at the Toyota dealer 2 days getting the oil changed.

My '08 Prius Touring is in the shop today because the 'check engine' light came on at 68,500 miles. I just got word from them that the catalytic converter is bad and needs replacement. Good thing I bought the extended warranty! Well, I searched the forum for similar problems and it seems like this is somewhat common, albeit on cars with a bit more mileage and maybe a year or more older. I don't abuse my car at all, though I often roll into full-throttle while merging.
Is this a symptom of a poor part design or of a system that fouls the cat over a certain amount of time? I'm not looking forward to replacing it again at 130K after my extended warranty expires.

I'm a rideshare driver who drives about 1000 miles/week. I currently have a Gen 2 which I love, but I'm looking to upgrade to a Gen 4 pretty soon.
-Does the Gen 4 have the same kind of under-trunk storage area in the hatch/cargo area? This is important for me on the Gen 2 because it allows me to carry equipment while having an empty hatch space for passengers luggage. Does it depend on if you have a spare tire or not?
-Real-world MPG in extended city driving with A/C on?
-Where are the 12v outlets? And extend one into the hatch area?
-Is there a notable difference in comfort for touring vs non touring models?
-Does the driver's seat with lumbar support make a significant difference in comfort?

My 2005 Prius with 86K miles regularly got 48 around town and 49 to 53 on long trips. I sold it to my son and his wife, they are also getting the same mileage. I bought the 2007 touring used with 41K miles and have never gotten over 41 mpg highway, and around town is 38 to 39 mpg.

I just purchased a 2008 Prius C Touring edition from CarMax. I have an appointment to bring it back but this may be a user error issue. My issue is that when I first hit the Power button the indicator light on the button goes green. When I hit it a 2nd time the light goes orange but stays on. When I shift to R or D it will shift to N but no further. I do have my foot on the break but the only way I can shift into R or D is to hit the power button twice more, to turn it off and back on. When it turns on the 2nd time, the indicator light on the Power button goes off. Am I doing something wrong?

My driver side headlight is out in my '08 touring (HID) I bought replacement bulbs on Priuschat recommendation. Swapped that one out, no change. Is the ballast next on the list?
Also, this may be a coincidence. But that headlight assembly seems to be a bit leaky. After a rain a fair amount of condensation gets in there.

I have a 2005 Prius recently replaced the hybrid battery. Not so happy with it, my mpg b4 was 49-51 mpg, now I only get 40-45 mpg. I notice the car is a little weaker and the ICE rev higher everytime I accelerate.

I have an '07 Prius Touring with about 95K miles that I have owned for about a month (after my previous '07 was totaled). My wife tried to drive it for the first time today, and the problem is that when my wife tries to start the engine, the dash lights come on and the color display comes on, but the car won't "shift" into Drive or Reverse (it will go into Neutral). A dash warning light also comes on that the owner's manual says means Take to the Toyota Dealer for Service. Then if she gets out of the car and then I get into the drivers seat, everything works fine.

I have a 2008 prius. Usually it gets me around 52-55mpg, I've had it since January. Since a couple of days ago its not giving me anything above 49. I know thats a normal number, but considering the fact that its usually quite a bit higher I'm wondering what the cause of the drop is. Also around the same time, when I pull out of my driveway I notice what appears to be a bit of water leakage. Its under the vehicle in the front center, and it only happens when I start the car for the day and pull out of my driveway (its on an incline).

I just bought a 2014 Prius- Pkg. 2 car. I had an '06 & an '08 Prius and kept the tire pressure @ 44 Lb.s for maximum mileage. I always fill my tank to the top well after the pump clicks off.
1) The dlr. told me I will only get an accurate MPG by not filling the tank after the pump clicks off. He claims the computer doesn't read the extra 1-2 gallons and that is causing me to get about 35 MPG even though the trip meter says 50 MPG.
2) The dlr. told me not to run my tires @ 44 lbs. Said it is a safety issue. I've been doing 44 lbs. since 2006 with great mileage and no safety issues.
Am I wrong for filling my tank to the top? My Prius has just over 600 miles today.

Ok, had the prius c four for a few months now. What is up with the gas gauge? When I get down to one rectangle my cruising range drops to like 9 miles. I got gas and put in 8 gallons, which means I had 1.5 gallons still. Why is it showing such low cruising range mileage? Looked through the manuals by couldn't find anything useful. Also, is there a way to see exactly how much gas you do have? The rectangles seem a bit arbitrary to me when it comes to representing an actual amount of gas?

I have a 2008 Prius and my car consistently tops out just under 40 MPG - I've never had a tank last over 325 miles. Seems like it's somewhat below the average.

2004 Lariat. Ford F150, 5.4 Triton. Whenever I slow down, stop, or turn my truck will read low oil pressure, then all my gauges drops and it stalls out. I've taken it to my mechanic twice now. And twice he's replaced two sensors. Today I took it to Wal-Mart for an oil change and they said its probably why my check engine light is on code, T19. I've had that light on for 4 years now and this stalling out problem starts 3 months ago. So far its had regular oil changes, new air filter, two new sensors and im scraping money to throw at it. Hitting snow banks, other vehicles, and tree's... need to find the real problem before I go broke or worst kill someone in an accident.

Working on a 88 Ranger 2.9L 5-speed ext cab. The fuel pressure drops off fairly fast when turned off and I'm pretty sure that the check valve is bad. My question is, which pump has the check valve? It is a single mid tank set-up and has a pump in the tank and on the frame.
Pressure is fine while running. about 30psi @ idle and 40psi with no vacuum on the regulator. The pressure drops off within a couple of minutes which causes it to have to crank over for a bit to rebuild pressure and start.
It looks like the frame pump is readily available while the in take pump is special order. I just need to know which one has a check valve. I'm thinking the in tank pump, but I hate to waste money for the wrong pump.
Pressure drop rate
30 psi @ shut off
25 psi @ 1:05 min
20PSI @ 2:30 min
15psi @ 4:45 min
still dropping

2 nights ago changed the fuel filters for the 3rd time on truck since bought it a year ago. It has 67,000 miles. F350 6.4 L 2008. The truck ran for about 2 minutes and then wouldn't start. For the last two nights have done everything including cycling the key over and over to purge air, replacing the fuel filters thinking the first ones may have been defective, pumped the gas pedal while trying to start it, tried to start it with fuel cut off switch held in, changed o rings etc. The first night I didn't get fuel at the head but after changing the filters a second time, I now have fuel at the head. That is the only progress I have made. The truck has gas and it is fine as we are using it in other trucks. The battery has never been allowed to totally deplete.

After oil changes (seen this 1-2 times now) on my 2009 Prius, I see a drop in mpg from 48 --> 45 or so. My driving doesn't change significantly, and I believe that the mpg slowly recovers over time.
Is there a reasonable explanation? Am I having my oil changed wrong? I usually get a 5W30 regular oil from Jiffy Lube -- nothing special. I decline the fully synthetic, because the 2009 model doesn't call for it, but would this affect the mpg?

I've read several reports about failed water pumps. Well, Pearl stated leaving drops of pink coolant on the garage floor a few weeks ago. I thought perhaps I had overfilled the overflow tank so I just ignored it. Finally warmed up so this morning had a look. Water pump! Pulley had lots of pink decoration all over it.

I have noticed oil spots under my 06 lately and finally got under it to see where it's coming from. It's collecting and dripping from the bottom motor mount but it's hard to determine exactly where it's coming from. I can't tell if it's coming from higher up or down low and running back and up from the wind. I just cleaned it with degreaser and have it running to hopefully dry it and be able to see where it's coming from.

Not all of the time, but sometimes, I hear a couple of clicks when I brake. It seems to happen for a while after first starting the car. It is only heard when pressing the brake. It may be intentional but I really have no clue.

5.4 L, Engine runs if primed at the intake. Fuel pump can be heard running but no fuel gets to the engine. Truck is mint and being sold real cheap due to this issue.
Fuel Pump? Filter? Both? I haven't seen the truck, a friend is considering buying it and rolling the dice it is a quick fix. Fuel is in the tank .....
