The service department told me to add BG44K at least once a year and make sure not to let fuel sit in the tank long periods. They have had issues with people who dont drive their vets very often. he said the sending units go bad and that it is an expensive repair, like 1,500.00

Some FI cleaners are solvent based which are ok to use occasionally as they can be harsh on rubber and diaphragms in the fuel system.
Other cleaners are based on detergents like redline.. These can be used more often without harm.
Solvent based FI cleaners mix with the oil during combustion and those who know only use them right before an oil change.. This is a little extreme.. but these are more than just cars to most.
I use redline like twice a year.. I have used solvent based cleaners in older cars with carbon buildup and other problems with great results..
No need to use in the spoiled pampered vette... IMO

That's where I am. I use AMSOIL PI at oil change intervals which is 7500 or greater.

How does the GM Fuel Treatment fit in there?
The bottle recommends using as often as every 3k miles, and says nothing about changing the oil after use. In fact, it recommends using it "at every oil change", which sounds more like adding it after the change and not before.
But GM occasionally goofs...

Several people have said the GM is rebottled Techron.

I use a combination of Lube Control's Fuel Power and RLI's Bio-Plus, per a well respected tribologist. 1oz per 10gallons.

I started a separate thread on this, just posted that Blackstone Labs says their oil analysis shows no problems with normal fuel treatments like Techron or GM Fuel Treatment.

Aggressive de-carbonizers or top engine cleaners might be different, I didn't ask.

If you use a Top Tier gas. If you you use a crap gas (BJ's etc.) it may not be.

I add techron (the small bottle for 10 gallons) after a oil change,which is about 5000 miles,some times less.

Gentlemen, when is the last time you saw a dirty or fouled fuel injector? Use a premium top tier fuel and spend your fuel additive money on something that will really make your car faster or more fun to drive. Fuel additives = waste of money = marketing. Also, for those of you who think that if a little is good, a lot will be great, you are wrong. Too much of certain additives can actually poison the system and cause expensive damage. If you must use an additive, follow the directions. Bottom line, you get all the fuel treatment you need in the fuel you are buying.

BG 44k once per year for my Corvette. For my other vehicles, 44k every 7500 miles.

Four Corvettes and close to 200k miles over all of them. Never believed the injector BS and never paid for it. And never regreted.

Save your money for real mods. Don't buy in to the snake oil BS.

And as for the whole ideology of switching brands every 500 miles (yes, I read the article) I'm not buying it, at least for my car. I'm tuned for Chevron 91 octane and that's what I use - period.

Full tank is better otherwise water will condense in the tank.

Gearhead Jim

Storing with a full tank reduces condensation, which is a bigger deal for light airplanes that are often parked outside with big temperature swings and are very sensitive to water in the gas.

Storing with only a little fuel is an advantage if the stuff starts to deteriorate, not as much to burn out and you can dilute it easily with a full tank of new fuel.

Your car, your choice.

Perhaps it's just my airplane background, but I prefer to store with a full tank. Since I never need to store more more than three months, I store it full of fresh Top Tier premium and don't worry about deterioration.

For the most part I would say additives in a Corvette used the way most people do is a waste. I have used them in my other vehicles and never noticed any improvement over the way they were already running.

I haven't used SEAFOAM in my 08 Vette because it's a relatively new DD and I usually keep the tank 1/2 full or more. I can comment SEAFOAM has worked great added to the fuel tanks in my 04 Tundra, BMW bike, boat, and three smaller lawn gear engines. I have a 14 y/o 2-cycle 120 Mercruiser, 14 y/o 1100 cc 4-stroke in the BMW, and a 15 y/o John Deere lawn tractor. They all get SEAFOAM gas protection 12 months a year, and all engines start right up and run smooth. I also use premium gas in everything plus methanol-free gas in the boat.

I would recommend you to try Techron or Lucas. Also Royal Purple is quite good but for more information check on http://injectorcleanermanual.com/ . They have much more cleaners. So you could choose the best one for you.
