Default Fuel Additives

Do any of you all use a fuel system cleaner, or additive in addition to premium gas? Just curious I got my first Vette and want to take care of it!

It's recommended to use a bottle of TECHRON (for 20 gallons) periodically. It's the same additive in CHEVRON fuel, but in higher concentration.
It'll help reduce the sulfur buildup that causes erratic fuel gauge readings. I use it about every six fill ups. COSTCO has something that is very similarly packaged, but I'm not certain if it's the same chemical makeup.
Also, use STA-BIL for winter storage.

It's pointless if you run a top tier gasoline.

Fixed my fuel guage problem, reading full all of the time. Carry a couple of bottles in the trunk to use about every other fill. We don't have any name brand fuel stations in my part of the woods.

I use the Costco stuff and it works great.

Do you know if it's the same stuff as TECHRON?

At six for $15 it looked like a great deal. I only casually read the box. It said it was for fuel injector cleaning...

BG44K once per year or every 7,500mi for carbon buildup and Iso Heat once per month to keep water out of the fuel system.

Yes it does have TECHRON on the label. And it works.

Thanks, I guess the key would be if it's the same concentration of TECHRON then. I'll check it out more...

I run fuel system cleaner once a month in mine. Never had any issues with my fuel system either.

I have always run "top tier" gasolines but was getting the dreaded, well maybe just confusing, "no fuel" on a full tank issue once in a while when the guage would act up. I now add a bottle of Techron periodically (no Chevron gas around here that I know of) and a can of Seafoam once in a while. No problems!

Thanks, also for winter storage do I
A.) Full tank (to prevent condensation) with Sta-Bil
B.) Empty tank (to prevent using old fuel)

When should I start the car in winter once a week, every two weeks, or once a month?

Sorry to jump in, but what is the difference between STP's complete full system cleaner and Techron's?
