Fuel system cleaners?
« on: Oct 24, 2015, 10:02 AM »
I recently had a bit of a pinging when the engine was under load, but the car has been tuned by Lew and this pinging just happened recently so after some sniffing around it looked like it may just be carbon build up. I ran some of the regular small bottle Lucas through it and now no more pinging, so either I had bad gas or the Lucas worked.

But as I started researching I found people mentioning "GM Fuel system cleaner plus" and "GM upper engine cleaner and fuel system cleaner". People are saying that either of those two things are as good as "Techron" because they are very similar. I'm just wondering what everyone else uses and since I'm in canada.... I don't see the "GM" label but I see a lot of the "AC Delco" labeled stuff... are they both the same product?
