No. Now, we don't get what you guys call "top tier gas". Until about 6 months ago, Premium was just a higher octane. It's only in the last 6 months they've started advertising the "cleaning" abilities of their premium fuel.
I love SI-1, and I use it on the second last tank prior to my yearly oil change. Having said that, I also keep an eye on my injectors and while the SI-1 helps clean up very mild deposits and keep a reasonable spray pattern, it does 2/10ths of bugger all for grungy injectors. I tried that by putting dirty injectors that I'd already tested for spray pattern in the car and running 3 tanks of SI-1 in a row. When they came out they were just as bad as when they went in.
It does seem to help keep intake valve deposits under control, but again it's a feeling. Every year I pop an injector out and have a poke around with a borescope, and since I started using SI-1 the valves seem to grow fewer deposits.
If you have dirty injectors, clean them properly (or pay someone to do it).

Just interested, how do you know that?

Get BG 44K. It's the strongest out there but you would have to order online as its impossible to find in stores. Not sure what the availability in the Caribbean is though.

I do not believe that anything that you pour into your tank can clean seriously clogged injectors. I had a Jeep where the oil was getting diluted (the dipstick level was going up) from injectors that would not close. In-tank remedies and even a "fuel system cleaning" from a local shop did not resolve the problem. I removed my injectors and sent them to Trav for actual analysis and cleaning. it worked wonders. I have two more sets to send him....
If you neglect the injectors and let them get THAT bad, that it starts causing problems with the engine, I honestly doubt any over the counter medicine (fuel system cleaner in this case) will have enough power to help.
I feel these cleaners in a bottle are more suited for regular preventive maintenance more then actual cleaning of very dirty and poorly functional injectors / valves, piston tops, etc.
I feel that any of these huge companies have enough budget and R&D cost that they can easily get two new engines to run side by side, one with a small maintenance dose of fuel system clean and one with plain ol fuel to see if there really is any real benefit to it or not.
As of right now, without actual proven data to back up their claim, we can only go off of reputation and their word that it works.
I run small maintenance doses in my cars, hoping that I'm not just burning money outta the exhaust pipe...

That would come after knowing for sure they actually are dirty and couldn't be cleaned.

Agree in principle but I changed mine at 150K because I couldn't see them actually working. Solved the problem I was having when bottled answers had failed. I got those cheap too. Were the originals dirty, spraying funny or otherwise failing? Didn't matter which and much potential pain time avoided was my rationale at the time. The value equation is different when the injectors are that cheap and there are only four of them. I sure wouldn't look at it the same way for a GM V8 for instance with those crazy parts prices times eight.
I ordered from an amazon retailer.
Expected some kind of hazmat label.
Nada.
So they may just ship wherever!

What's the average price for cleaning?

BG44K is the only in tank fuel cleaner that may help you.

No clue what the average is, the one place I have gone to was $22 per injector plus $12 total for shipping.

Do you all think that redline si-1 fuel system cleaner and a tank of premium gas can properly clean out dirty injectors?
thanks
1. Use the full bottle Redline SI-1 with a tank of the usual octane that your car requires.
2. Then after that use 1 oz per tank of the Redline SI-1, to gradually clean the rest and maintain.

I've been meaning to try BG. Is it really as good as everybody says?

I'm loving it in my truck.
Smoother acceleration, deceleration and power delivery, therefore even smoother shifting IMO.
