Injector Cleaning Additive

The ONE year I didn't put an additive in the tank, I had goo plugging the jets of my (Valkyrie) motorcycle, AND standby generator - come spring.

I had similar issues in spite of (or because of??) Stabil (sp?) in my mower, and standby generator, leaf blower, pressure washer, and string trimmer. (My small engine mechanic told me to NEVER use Stabil. Use Sea Foam instead.)

I used to put a pint of Sea Foam in each of the Vette's tanks in the fall. But, because I make it a point to start them once a month all winter long, I've never had an issue, long as the tanks were filled with fresh fuel before storing them. So, for the last 5 winters, I didn't use anything in the tanks. They ALL fire right up and idle - as well as expected (given the cam overlap of a couple of 'em!).

And, as a rule, I don't shut the fuel off on the mower or other small engines when storing over winter. That way the fuel will NOT evaporate in the carb jetting - and a little Sea Foam is in there for good measure...

So...

Sea Foam (winter storage insurance policy) in the small motors, and leave the fuel petcock open to prevent fuel from evaporating in the carbs(!).

No additives in the Vettes. A full tank of fresh (E10 ethanol) fuel in the fall, coupled with once a month starting/warming has worked fine for 8 years in a row.

Now, my bigger worry is RODENTS during winter storage. (I hates mieses to pieces!)

Your mileage may vary!

Sure would be nice to be able to buy 93 out west, only 91 available or race gas

Put a bunch of Bounce dryer sheets all over the Garage . Mice hate the smell of bounce . I replace them all halfway through the winter ... I think someone else mentioned that trick on this awesome forum so that's how I knew about that .
I forgot to put stabilizer in my 3 bikes so lets see in a month from now how it works out . All have Hightest Fuel with no Ethonol ...
The Vet's have stabilizers in there tanks .

And mothballs for snakes after you get rid of the mice!

FWIW, Mike, the ONLY time I've had issues with long-term storage (i.e., winter), was when the fuel supply was shut off and what fuel was in the (carb) consequently evaporated to leave dissolved crud in the jets. (The Valkyrie had 6 ITBs, and apparently that really increased the chances of issues when I shut the fuel off w/o Stabil or Sea Foam in it.)

Course, there's no simple way to shut off the fuel to the injectors for storage. So, I'm a believer in running the LT5s once a month if only to keep them from clogging up! Seems to work. No issues in 16 years of winters and no Corvette jetting fouling (knock on wood!).

I have a 1990 ZR-1 and use Amsoil oil as the LT5 engine requires more acidic oil, and use 91 Octane gas without ethanol . Never put injector cleaner in it for 5 years and no problems as manual states never add injector cleaner.
