The best thing you can do is to run a good fuel system cleaner every 5,000 to 10,000 miles. Cleaning out the fuel system and injectors will keep the car running smoothly.:thumbsup:

[talnlnky]

or just pay the extra 2cents a gallon for good gas (like chevron)... and you'll have nothing to worry about.

[bronsin]

Change the plugs and air filter and the transmission oil if you have a manual. Get to know the parts of the car that are inspected like ball joints, CV boots etc.

cool..i guess this modern cars dont need timing readjustment... fuel line cleaner sound good..

I'll put money that using fuel cleaners every 5,000 miles will result in you replacing a fuel filter or pump before you would get any buildup had you never used cleaners.

Fuel filter? Where is this on the sedan? And how many miles before you change it?

Why? Do they damage the parts? I used Techron two tankfuls in a row with no probs. They were the 12oz. sized bottles.
Also, last time out I put Sunoco Ultra in to see how it runs...GREAT!

See you in a 100,000 miles and we will find out.

IMHO, fuel injector cleaners are a waste if being used in new(er) cars, i.e., anything younger than 3yrs old or has less than 36K miles. Frequent use of cheap gas and air filter malfunctions are variables to be considered, of course.

Please read. I didn't say fuel injector cleaner.:frown:

Sorry. But you did mention fuel injector, and for some reason, that's all I remembered. :smile: But even still, you would come out cheaper just running on a tank high octane fuel to clean out your fuel system as opposed to paying $6 on a bottle of over-hyped detergent. Most fuels have detergents in them anyway, and filling up with a higher octane would only cost you $1.10 more per tank and would yield more noticeable benefits, I believe.

The FF is on the fuel pump which is in the gas tank. There is no change interval speced, as in the ECHO.

Does it work even after 2.5 years of using cheap gas? Never had any problems with the car, but I changed my exhaust 2 weeks ago and also filled the tank with Chevron. The funny thing is, I seem to be getting a better mpg on this tank and I don't know whether it's the exhaust or the gas. It's probably both :smile:

So, back to my question, will using better gas clean the injectors over time or should I use something else? And if so, what should I get? Anything from the gas station or is there some secret power potion? :iono:

There is a secret power potion, unfortunately, it's still a secret.:rolleyes: The real secret is to do regular prescribed maintenance. Anything more than that is because you love:wub: your Yaris.:thumbsup:

What kind of fuel system cleaner doesnt clean the injectors.?
And as fuel system cleaners are formulated into the gas at the pump i'll also agree with posaunemeister that any kind of fuel additive is a waste of money,you'd get better return on money by buying wife/mom/girlfriend a bunch of flowers and then taking them out for supper:wink:

You are free to think and do whatever you want. Buy flowers, if that is what you want. I don't rag on your beliefs. :mad:

[severous01]

i'd run a full injector cleaner after about 50k miles and be done with it till 100k. u can gtet a shop-air operated fuel system cleaner from mac/matco/snapon. and you might be able to get one from autozone.

any way, pull out fuel pump relay or fuse (pref fuse if it's easy), run car till it dies. pull fuel line and find adapter for the tool. insert and install tool adapter, connect to tool. fill tool bottle up with supplied cleaner or cleaner of your choice. supply air feed to bottle. set to standard fuel pressure. most EFI engines are between 35 and 55psi. start car, LET IDLE until car dies again...remove tool, reinstall fuel lines and fuse. you're done.

is it a pain? yeah, but it works much better than those cheesy knockoff fuel system cleaners.

[marcus]

i guess the main key points here is fuel cleaner will definetely clean the lines but gunks has to go somewhere and thats where to fuel filter is for i guess if it gets full it need to be replace.. so do fuel line cleaner then replace fuel filter..while ur at it change ur oil and air filter...:thumbup:

actually, if you are gonna dump snake oil (tne up in a can, so to speak)
in yer car, to clean out fuel and deposits...

use BG-44k. it is what most shops -actually- use, and actually works.
nothing is better without taking the heads apart.

anything with the same volatile components bg-44k has will do the same.

it only works on motors that are suffering...it won't do diddly for an engine
that:

sees weekly 2 hour runs (to evaporate moisture in the oil)
and weekday daily short drives (this is abuse...normal driving)
and is fed name brand gas and synthetic oil


the KEY to engine longevity... is weekly long trips to bake out moisture
from the oil, and drain the gas tank. if this never happens then the
stuff like BG-44k can work wonders on cleaning deposits and carbon

[Lazerdot]

Snake oil...really, geez.

Let me know if you want to try some "snake oil"... see my previous thread.
