well....for those of u who live in LA, u know that gas price is going down....but still....i was trying to use those fuel injection ....but i forgot what brand to use....something with..."STO"....so can anybody tell me what's the brand of that...or a good brand of fuel injection?? and is there any way to save fuel economy besides this?? need everyone's suggestion~

 

Fuel additive = bad (check your car manual)

save gas = drive slow and steady

 

you are probably thinking about STP and if you go with that get the black bottle. in my past car, i ran chevron techron (larger bottle) and it seemed the best job of all the ones i tried. there some new stuff called X1-R that i hear is the best stuff out right now.

 

Basically I only feel the difference when My car have more than 40k miles... otherwise, I don't find any different adding those stuff. Also, I think an engine flush would be better than adding those stuff..

 

Tire pressure could be also a reason for bad mileage

 

multiple ways to improve mileage

tire pressure/optimal spark & timing/clean filters
no jack-rabbit starts/no quick stops/coast where possible
and many more that usually can be found at cars.com

 

also,
anyone else found that fuel BRAND makes a difference?
i find that Exxon/Texaco return the best mileage...
who else

 

Chervon is quite popular among Maxima Drivers.

 

my vote would be for either exxon or amoco
