can you do a fuel injection service on a 05 mazda rx-8?

I recently went to wal-mart to get a fuel injection service and the mechanic send he couldnt perform the service because of the seals on the rotary engine. Is this true?

1. yes you can do it but read carefully the instructions and for how many gallons is the product you are gona use if your car is running good and give you good mpg no need to use the product
2. Why do you think you need one? A barely three year old RX8 should not need tinkering with. Rotary engines are not easy to work on, unless you are competent mechanic you should leave well alone. Go to your local dealership and ask them for advice first.
3. What on Earth are you doing taking an RX8 to Wally-Mart for vehicle service??? Please, please find a rotary expert in your local area. (p.s. I wouldn't trust a W-M mechanic to pump gas in my car without screwing something up...)
4. IF the Wal-mart tech actually does fuel injector cleaning by disable the RX8 fuel supply to injectors and then connect injector cleaning tool to your Mazda RX8 fuel injector high pressure line (remember: FUEL line) then run your engine using pressurized mixture of gasoline and strong cleaner: it will be OK. Most general repair shop and fast lube place will not do this kind of service because it requires higher skill technician, lot of information about fuel system of many make and model and lot of fuel line adapter (expensive) to work with many make and model. So they normally do something else and call it injector service. They will add a can of injector cleaner into your gas tank. Everybody (including you) can do this by going to buy a bottle of injector cleaner and add to your gas tank at fill up. Next, they will install a UNIVERSAL kit to intake manifold to allow some kind of cleaner fluid to be draw into intake while the engine is running. This fluid will be burned in engine combustion charmber but never went throught injector at all so it will not do anything to clean your injectors. This service is harmful to your engine and emission system (especially Rotary engine). It can damage catalyst converter, can cause engine lock up, long list of problem........ If you really want to have injector clean, find a shop where they really do it. If you want Wal-mart way, just buy injector cleaner off the shell to add in your gas tank at fill up (waste of money)
