I can only comment about the injector cleaner. At the risk of upsetting sales reps etc, I will say that the following is my opinion. Complete WASTE of time. As Mr RX-7 says, it is only good to keep clean injectors clean. However, by the time you add up the cost of running the injector cleaner regularly, it is heaps cheaper to get an off-car injector clean every 100,000km
Removing the injectors and performing an off car clean achieves the following:
1) runs straight cleaning fluid through the injectors to remove the gu buildup (additives to fuel are too dilute to do this, expecially with very dirty injectors)
2)Volume test - tests to see if all the injectors are running equal flow through them ie not lean on one.
3) Drip test - test to see if an injector leaks fuel into the cylinder
4)Replacement of filter baskets
Normal retail value is about $30 per injector plus removal and refit. So for a 4 cylinder Corolla, you would be looking at;
(4 x $30) + 1 x $60/hr labour = $180 absolute max. Twin cam injectors should be able to removed and about 15 minutes. VL commodore is about 3 hours, VS commodore is about 5 minutes.
As to why the dealers put it in - they make heaps on it. When mum used to book her car in, they would push her to get the injector treatment and then charge her $80 for it. It was the Wynns injector cleaner they were using.
So my opinion - off car injector cleaning is the ONLY way to do it.
