Hey guys, I am writing this thread just to share this little information with everyone here. I have a 1998 Toyota Camry V6 with 131768 miles. I bought the car used on 2nd August 2006 with 119000 miles. I was getting about 25-26 miles to the gallon when I purchased the car. This was the best mileage I was able to achieve while driving on the highway. I was not particularly impressed but a car with 119000 miles on the clock.... I was not hoping for anything better. A couple of months ago....around the mid of December 2006, I bought myself this 3 foot long sweeping brush which has a diameter of about an inch and has bristles which run along the length of the wooden stick. I use this to clean the throttle body. I also bought 4 cans of seafoam and sprayed an entire can in the TB and took that long brush and just got to cleaning the TB. I could not believe how much crap came out of the hole of the TB. I took another can and poured the entire can in the oil case and drove for 100 miles with that stuff in the crankcase. Took the third can and ran the entire thing through the brake booster line. The last can went in the gas tank which at the time had approximately about 2-3 gallons of gas left. After I had dont all that....I took the car for one hell of a ride on the highway.....I redlined the car and reached the speeds of 130 mph...I did this to clean all the crap in the TB and to burn off all the seafoam......I did all this crazy driving late in the night around 1:00 am. After that day, I started recording the gas consumption of my car . Everytime i got gas...... I would fill up from the same gas station and the same pump. I do not fill anymore gas after the pump has clicked....also I would get the gas at approximately the same time which was around 10 pm in the evening, just to keep the variables stable. Just to give you an idea how I drive on the highway.....I dont drive like grandma....but I dont push the car to the redline either(for the purpose of testing the gas mileage).....on the highway....I dont draft anyone but I do drive at speeds of 75-80 miles an hour and not any slower. I have managed to get 30 MPG contantly over the last month or so. I have also achieved 31MPG quite a few times. If it matters to anyone.....I also put in the K&N drop in air filter....I know I know....it does not add horsepower or anything....I just dont like changing filters all the time.:lol: I also use Mobil 1 5W-30 throughout the year with Purolator PureOne oil filter. I know that this might not be a big deal to many but it is for me because I do 90% highway and 10% city driving.... and to get this mileage feels good.....LONG LIVE CAMRY'S:thumbup:

That is some crazy good gas mileage. Probably the best out of anyone on here with the 1MZFE non-vvti. Most of us are getting around 20mpg, including myself. In the springtime I need to clean out my TB...seems like it does a lot of good to clean it out. Also a good tuneup is needed. I'm hoping to achieve 25mpg some day. I drive 60% hwy and 40% city.

I have a 1998 with a v6 with 140k on the clock and i get about 25 mpg on the highway at 80 mph so 30 is quite an improvement. brand new these cars were only rated by the epa for 26 mpg. i guess i need to get some seafoam.

Did you drain the oil and brake fluid soon after doing that, or are you keeping the seafoam in there for a while?

last time I checked the can you arent supposed to use the entire can in the oil, brake booster or with 3 gallons of gas.

I'm not sure about some of those, but it says it treats gas tanks from 8-18 gallons or so, so I would say you shouldnt have less the 8 gallons in your tank when you use it.

The trans tune says to use .5-1 of the can in the tranny, not sure about the oil,

You are absolutely correct about not using so much seafoam.....however....I didnt know that until I had done what I have stated above.....I probably would never pour that much seafoam in this or any car again....that stuff is really strong and I am just glad I didnt damage anything....atleast I think I didnt:lol: ....but yeah.....I cannot stress how happy I am to get this mileage.....cause I am a college student and I am broke like 10 months of the year.....looking at how expensive gas is these days.....every little bit helps....so all you guys out there who get bad gas mileage even when you drive moderately.....I recommend you follow what I have done....who knows it might help.....and one more thing....if you have a V6....try to use 91 octane....I have tested it several times and I always get lower mileage when using 87....but of course if you dont want to use 91 its your choice. Keep your tires inflated to atleast 36psi.....and of course.....drive nicely....if not like a grandma;)

geoff5093 "Did you drain the oil and brake fluid soon after doing that, or are you keeping the seafoam in there for a while?"

I kept the seafoam in the engine for about 100 miles....I was not planning to do so but an emergency occured and I had no option but to drive to another town with seafoam in the oil.....luckily it did not damage anything....I changed the oil as soon as I got home and was surprised at how dark the oil was.....btw...I always use Mobil 1 fully systhetic 5W-30....I have experienced really good gas mileage using this oil...Cheers

I used to get 29mpg in my 94 V6 until this past year. Now, it's more like 26-7mpg.

BUT my city mileage SUCKS! something like 15mpg. this is in lots of stop and go hard city driving but still, i should get better mileage than that!

holy smokes thats impressive. best highway i could manage was 28 going about 82 mph. So i guess i could achieve 30....but in the city in stop and go i drop to about 16. Average mix driving i get 19.

i may try deep cleaning my TB, i only cleaned some of the tb last time, but even that helped a lot. I'll do it before my next oil change.

^ Yeah man, try to go to walmart and go to their kitchen cleaning section, there they have this brush which is really really good for cleaning the throttle body because its long enough to reach the plenum and its also about an inch in diameter which is the perfect size for cleaning the TB and stuff. If I do about 40% city and 60% highway which happens atleast once a month if not more, I get around 24-25MPG, which is still really good. I think that maintaining your car is the key for good mileage, the person who owned the car before me, probably took excellent care of the car because honestly the car looks new inside and out.

I just filled up and I got 16mpg. It's because the high right now in Minnesota is 0 degrees with a -40 degree windchill. Also it has been a lot of city driving. I hate winter! Bad gas mileage and my car is starting to rust from all the damn salt!!!

WINTER FTL!

tigermonkey - that is pretty normal mileage, you could definately be getting a little better, but not much.

I'm just currious, My daughter's stock 94 -V6 gets 20-21 city and 29-30 straight highway, I was a little disapointed in the city mileage. From what I see here, she is doing pretty good.

Is it normal to get such low city mileage as what I see here or do you guys have them modded out and petal to the floor all the time.

Doug S your daughter must drive pretty decently to get that kind of gas mileage. Yes, that city mileage is excellent....I havent done 100% city driving but I am sure that I would be getting around 19-20 mpg....the V6 particularly is not really good with city mileage.....on highway the V6 shines IMO.

I usually average from around 20-23mpg in the city. Lately it has been alot better with the 91 octane I have been putting in. I've gotten a pretty steady 22mpg as of late.

I gotta try this seafoam nonsense, and clean the throttle body too. Also due for some tune-up parts... getting to 100,000miles.

Best I've ever gotten with 89octane driving pretty much straight highway was 29.3mpg... So thats really amazing gas mileage.

94coupeV6 - I know all about the cold problem man! -10 windchill right now... and dropping


Btw... Doesn't the spec sheet say 20-28 for the V6?

^ you are correct about using 91 Octane....it does indeed give you better mileage on the V6....I dont mean this as a generalization but a lot of people dont use 91 Octane in their V6....I personally think that they would notice quite a difference in their gas mileage....of course one thing that everyone needs to recognize is that no one will notice a huge difference right away....atleast I didnt when I switched to 91 Octane....it takes a couple of hundred miles before the car engine can get itself tuned correctly....but dont quote me on this.....I am just sharing my personal experience

Thanks, My wife drives a Sienna that has a similar V6 in it, (looks about the same anyways), she gets about 18mpg City and has a serious case of lead-foot (big time). I was expecting alot more from the Camry since it's a smaller vehicle, and yes my daughter seems to be a very good driver. I am continually impressed with how this Camry runs, it sits outside and it's really cold right now, starts right up and not an (odd) sound from the motor. Only issue with it is a loud squeek from the right rear when it's cold, kind of drives me nuts..

I usually get around 21mpg with 87 octane. I decided to fill up twice using premium 93, and in both time my gas mileage dropped to 16.5mpg. Then I filled back up with regular 87 and my mileage went back up to around 20mpg.
