Well, here in California (San Francisco Bay Area) we just wax it, fill it up with gas, clean the sun glasses, put the key in the ignition, start it and back out of the garage, let it warm up a minute or two, and hit the road! Oh yeah, about mid-January I need to put the top up when the temp drops below 60 degrees.

I feel sorry for you guys (and gals) in the Snow Belt! I say just go for a short cruise . . . Oh, say about 6 months long . . . . To a warmer climate.

 

In Texas, we rarely 'lay-up' our C5's, but from a very long background with inboard ski-boats, the winterizing procedure calls for - as routine as the day is long, to change the oil/filter. Add Stabil to the fuel tank then run the engine for a minimum of 20 minutes so fuel/stabil gets to injectors.

The very last time it is started, use a FOGGING oil spray (from any marine shop) and squirt for about 10 seconds into the intake at idle, then shut it down. Do not re-start.


Then, other routine stuff, like draining the block of water (open cooling systems) or pump in eco friendly anti-freeze, remove a few hoses and rubber impellers, then coat the engine in a fine mist of WD40 for the winter. And, moth *****, whatever inside and covered.

The fogging oil coats the cylinders, head, valves, with a heavier longer lasting oil. When it is started up again in the Spring, it will blow white smoke for about 30 seconds, then good to go.


Seems to do the trick in the hi-performance wakeboard boat engines.

Just never seen it here on long auto lay-ups???

 

Does anyone use a Car Capsule for the winter? Here is a pic of mine.

 

I just my oil changed 500 miles ago and I'm about to put it away.
I'm now debating whether to change it again since it's been so recent.
I thin it'll be OK since I might take it out anyway on a "nice" winter day (if there is such a thing in VetteWorld).
