MPG suckathon
Ok so I got tired of the usual 27Mpg in the Camry 4cyl. So I
Added K/N airfilter Reset computer Aired up the tires to 42psi Kept the cruise on and stayed below 68mph Short 4min warm up this AM (28 degrees here) Light acceleration And TA DA 27MPG :mad: Test drove a Prius today..... |
Why'd you reset the computer? You may have lost stored information that contributed to better FE, :p
How was the prius? |
Well you'll do better in the Prius, no doubt.
But maybe you actually did *better* after your changes than you would have otherwise. FE drops with temperature (esp below 60's/70's). If you were getting 27 when it was warm, and now you're getting 27 when it's colder, I'd suggest you've actually made a decent improvement in efficiency. |
If you're doing short trips in colder temps and your mileage is holding you're doing very well.

I was going to suggest that as well. Maybe his driveway exits onto the freeway though ;).

Not a big fan of K&N unless it is for a race car...not a great filtering media- I would look into an Amsoil EA Air Filter Good stuff...maybe drop to just 65 or so Fuel Injected ... warm up not a big deal...are you running synthetic oils? Good Stuff Got to let your computer relearn your new driving techniques Probably running 34-36psi before...go to 46 or so |
my old camry did the same thing.. it was a 93 auto 4 cylinder. always got 23 mpg, no matter what i did. aired up tires, air filter, weight reduction, etc
|
Too many variables at once...
I'd put the stock filter back on. I'm not sure if there was an advantage to resetting the ECU with all of the other items -- what SVO was suggesting. Idling has proven to be a terrible way to warm up. Just drive slowly... Colder weather hits FE pretty hard. Give it a couple of tanks, and get a feedback device. The fill-up method may have been flawed. I'd like to have the option of buying a Prius when things don't go well :p RH77 |
As if you didn't have enough recommendations and suggestions. I will add that the slow acceleration could be hurting too. Its important in an automatic car to get the convertor locked up as quickly and cheaply as possible. Once locked you should work very hard to keep it locked. FE driving is very much a learned habit. You will see gradual improvement over time. Once learned its hard to forget.
