I am a noob on these cars so sorry for dumb questions...I cant put injector cleaner in my 89 Maxima so I was wondering if I can use it in these cars..

why can't you put injector cleaner in you maxima? is it carbed? if a car's got injectors i say put some cleaner in it. there are even cacrb/injector cleaners out there that work on both. it wont hurt a thing

I'm a fan of techron concentrate

I put one in my cars every few thousand miles.

if you actually believe to have problems with your injectors being clogged.... pull them out and take them to a place that does blueprinting & balancing.... costs like $50 for all 4 injectors.....

Or you can ask around your town if they have what is called AUTO RX, good stuff!!!!!!!!

My dad puts injector cleaner on his 90 maxima, I don't recall him having any problems with it because of the cleaner. Although he does have the injector problem that this motor is well known for.

I'd recommend a good tank of premium once a month or something, rather than injector cleaner. Many mechanics will tell you it's unnecessary and can actually cause damage. I think I saw some posts last year where people mentioned the troubles thy had after using it.

I used it in my Talon around 1997 or so and it dropped my fuel mileage and throttle response (still don't know why). A guy I know used it in his AE86 a few years back and it started blowing smoke a day later. Maybe it dissolved the gunk that was on his seals, which were keeping compression good?!?!

Remember: the injectors are the single most reliable component on your car (especially on Toyotas), so be careful what you do for (or to) them. If it ain't broke, don't fix it...in other words, why do you think you need cleaner?

So don't change your timing belt if it doesn't snap? The "if it ain't broke, don't fix it" philosophy never stuck to me.

Part of good maintenance includes reducing carbon build up. A car with little carbon build up will run smoother and more efficient (in power and mpg) than a car with lots of carbon build up. Valves seal better, better air flow, reduces hot spots, etc.

Just as you gave out your talon as an example, i can tell you about my corolla. I was getting 30mpg with the car, then it blew a headgasket at 285k (this engine has never been rebuilt). When I took the head off, I had it pressure washed and cleaned up while I cleaned up the carbon on the pistons. Once I put everything back on, I started averaging 32mpg.

FYI, those additives that they put in premium fuels are injector cleaner compounds. That's why they all advertise "cleans your engine as you drive" now. However, it's in much smaller dosage than a bottle of concentrated cleaner. A bottle of good cleaner will work better than that premium tank of gas.
