I'm basing that off a quote made by someone that said after adding it after a few fill ups they could physically see components getting cleaner but that it wasn't instantaneous.

I'm sure under most circumstances that adding it the cleaner to a tank of gas each oil change would be enough, but considering the bad gas mileage I'm getting I'm wondering if the guy before me wasn't just running 87 octane or something. He seems like the type I noticed him go 8000km between oil changes.

No

Yes anything you are going to put into your car to clean, you want it to take a bit of time to clean. You do not want to clog anything up.

Only way to instantaneously clean the injectors is taking them out and putting them on a bench.

One bottle of redline, split into three. You got 800-1000 miles on a bottle. If you want pull a spark plug take a look at the cylinder, run redline for 3k and check the cylinder again. You might be impressed.

Cool thanks for the tip. What do you guys think about getting the fuel injectors serviced at the dealer then just running stuff like redline from now on? I'm just worried I'm gonna throw of my dyno maps if my injectors are a bit clogged.

Thanks

^ I dont think the dealers even have injector benches. I would make sure before spending money on it. Redline works over 3k + miles were bench cleaners are done right there and then.

All the dealer said was that they hook them up to something to purge the lines or something like that.

In a high mileage car nothing is going to clean them properly and regain the correct spray pattern save injector removal and ultrasonic cleaning.
Ever try cleaning a cylinder head or valves of build up and found there is hardly anything short of physical scrubbing that will remove that crud?

So do you think that just running a fluid through your injectors is going to do anything short of maybe unblocking a chunk and further trashing your injector spray nozzle pattern?

Just about all the quality fuels out there already has additives that will work better than any off the shelf cleaner so you may be better off saving your money and put the best fuel you can buy in it instead.

A product worth mentioning tho pricey is ACES IV ( google it for info).
I can notice the sluggishness on a hot summer day in my G and sometimes faint pinging and the ACES helps with that.
I also use the stuff in my diesels and the gasoline product in my jet ski's.
I run 215 pounds of compression, porting, advanced timing on 93 octane and it has kept my motors from sticking ( detonation) - any of you guys that are familiar with 2 stroke engines know all about the fun things that can happen to tweaked 2 strokes.
Many of the hi perf outboard guys swear by this stuff too
