Hello,
I have a Daihatsu Sirion 1000cc 2006 which I got about 3 years ago. It does not have any issues but since I don't know anything about how it was treated before I got it I would like to use some additives to clean the fuel system, the injectors etc.
I have found sTp and Wynn's products in a local DIY store and could not find any other brands anywhere. Does anyone have any experience with any of those ?
Which brand should I choose ?
Thank you
Chris
Either or will do the trick, Wynn's looks to be considerably less expensive so I'd go with that
If you want to try one of those two, STP would be my choice.
Won't get into the who-believes-what-is-real bit.
Neither. Both are composed of 100%...
Any alternative you suggest then ?
Actually I though at first you were asking about their "stop oil burning" products.
Their fuel system cleaners are probably OK but Chevron Techron is about as good as it gets before resorting to professional injector cleaning if you can find it in your area.
Scotty has recommended Techron repeatedly. I've used it and gotten good results, too.
@Glen_stet, same here. Really Techron is the only fuel system cleaner I've tried over the years that produced any kind of noticeable results.
