I usually put fuel injector cleaner every time i change my oil. I'm changing my oil out in a few days and im wondering if you guys knew of any really good fuel injector cleaner i should use. + do you guys know of anything else i should put in / do to my car to increase the gas mileage or perhaps increase the longevity of the engine. I've already tried the K&N air filter, which im very satisfied with. 98 ES3 with 97,000 miles.

Fuel injector cleaner at each oil change? I wouldn't do that if I were you. You're only gonna accelerate the damage to the diapragm of your fuel pump. If you want longevity, regular oil changes is all you need as well as your other maintenance like tune ups and etc. Keep your tires properly inflated to help your mileage. If you stick to one or two gas brands, there is no need to use injector cleaner unless you have heavy carbon buildup from poor quality fuels. I use Chevron Supreme w/Techron all the time. If you want a good cleaner, the Chevron Techron or regular fuel injector cleaner works well. I wouldn't use it at every oil change though. Waste of money.

What about "engine immobilizer" or something like that. What does that do? Banana GS wrote about it on one of the threads.

I agree with flip, there is NO need to use a fuel injector cleaner that often (I use Valvoline synpower "complete fuel system cleaner" once, MAYBE twice a year depending on the milage I do), as it's overkill & a waste of money. His other suggestions are correct as well. I use Sunoco Ultra 94 gasoline so stick to a quality gasoline as well. Put the fuel system cleaner in your tank before you fill up just before going on a nice long highway drive for best results.

An engine immobilizer is a theft deterrant device. There is computer chip on the car & in your key (factory ones at least) and it has a signal one sends to the other in order to be able to start your car. If you don't have that chip in your key or someone tries to smash your ignition & steal it, since there is no signal, the fuel system will shut off so now the car can't be started. Generally speaking, unless the thief has a forklift or something simular, they can't steal your car......or at least drive it away. IF your car has one, the owners manual should explain it to you in more detail.

If you are going to use the injector cleanner try Lucas brand found at Kragens $3.95 a bottle works great use it on my cars and boats

If the injector cleaner isn't good when you do it to often, then why do the manufacturers say put it in every 3000 miles?

It's called marketing. If you read your Lexus owners manual, it doesn't recommend putting it in 3000 miles. If an aftermarket company told you that you need to change your engine every 50k miles, would you do it? Come on now. It's all common sense.
