Hello Fellow Corvetters!

I am in the process of prepping my vette for winter storage and read a few threads that mentioned once the vehicle is in its final resting spot, start it one last time and pour SeaFoam directly into Carburetor until the vehicle dies.  There will be tons of smoke but at the end of the day, doing this lubes the top side of the valves and cylinders, and helps ensure a smoother start up come Spring.  Does anyone have any experience with this procedure and can offer some tips?

Thanks in advance!

I have used Sea Foam for a number of years. However I have never used it as a fogging oil in a four stroke motor. I use it as the directions state. Pour the proper amount into your gas tank. Run the motor for some time. The stuff does lubricate carb, cylinders, and anything else the fuel runs through. The good thing is it also removes moisture and stabalizes the fuel in tank. Some use Stabil but it doesn't do near as much as Sea Foam. I do fog my outboard but a 2 cycle motor is a whole different story. However I use fogging oil not sea foam. Just my .02 on what has worked for me for years. Hope it helps. T

Seafoam is petroleum based so it would probably be advantageous in doing it. Id check with Seafoam Mfg  first .  Whatever you select, after youre done, id seal up the carb top real well .  Id also opt for taking the car for a good spin during the storage period on a nice day  every month if possible.

I've used a lot of Seafoam but will change brands this fall.....
Here's a cut and paste off another site.
 
Older types of stabilizer such as Sea-Foam are based on IPA (isopropyl alcohol). Those work fine with “pure” gas, but should not be used with ethanol. IPA picks up water like ethanol, but unlike ethanol, it does not phase separate. So as long as the gas does not have ethanol, IPA based stabilizers will keep you out of trouble. But if you do have ethanol in your gas, IPA will not give much protection because there will be much more alcohol in the form of ethanol than in the form of IPA, so the ethanol behavior will control rather than the IPA behavior. So if you have gas with ethanol, as most of it is, you should use a stabilizer that specifically says “for use with ethanol”, and does not use IPA as its active ingredient. Sta-bil is one such brand, and there are others.

Thanks for the reply, TheyCallMeDave!

Can I ask why you suggested to seal up top of carb after using Seafoam?  how do you seal up yours?

Thank you!

Thanks, JohnU.  So basically we should look for a brand of foam that says "For use with ethanol".  I do not have ANY ethanol-free gas stations within a 100 miles of me.  I feel guilty every time I fill up Red Velvet...like a bad parent or something! Thumbs Down

Probably just a baggie and a rubber band.
