Fuel injector cleaner shelf life?

[Pete491]

I found some old gumout after doing a garage cleaning and not sure how old it is but it was from their Regane line. It still is sealed with the foil cover under cap and has been kept shaded in some shelves. I was wondering if there would be any harm in using it as i don't like to see anything go to waste. I was planning on running it before i do my next oil change.

Dont use it if its old, just buy some techron. BOGO at advanced now, just bought some today and threw it in before i filled up. Techron has worked the best for me.

Yeah i stocked up on techron when autozone had the BOGO. Used it right before i changed my fuel filter. Just trying not to waste something i could be using.

Unless the contents are no longer clear and clean, I would use it.
