Two stupid questions
Be nice now fellas.
One: like many others I find that my hood light is disconnected at the plug on the front support. Is there a common reason behind so many being disconnected? You know, light won't go out, short or something like that.
Two: I bought my 2000 C5 from a dealer and he kindly filled the tank before delivery. I believe it was most likely 87 octane regular. Anyhow, performance was less than exciting. Since I am putting the C5 away for the winter I bought a bottle of Techron (the large bottle, cough cough $12.99 at Autozone) and filled the tank with 93 octane premium (about 4 gallons). Wow, what a difference. The car will spin the tires without brake torquing, just mash the loud pedal. Question, just how much does the car detune with lower grade fuel in the tank?
Thanks.

The hood light is usually disconnected because the owners don't read the owners manual to learn that the light will go out automatically in approx. 15 minutes with the hood open.
That's not to say there can't be a defect in the light assembly...

I disconnected my under-hood light years ago.
De-tune? I don't know, but I think higher octane is much better.

you won't know about the hood lamp until you re-connect the harness. it could be something simple like the previous owner had it disconnected because he had the hood up at a few shows, etc. even though it does go out (eventually, lol) it will usually re-light if there is the slightest breeze to shake the hood a bit (the sensor switch senses the hood had been "re-opened", etc).
as for the difference in the fuel grade. it certainly will make a difference in performance. i'm surprised that the dealer put a lower grade of fuel in it then the OEM specs call for as the recommended octane (93 in most places, 91 in california, etc).

OK, I understand the hood light issue. I think I'll just leave it disconnected.
As for the fuel and performance, it was a Ford dealer and I doubt that they cared what the car called for. I believe it was something less than a half tank that was added. And performance now is much improved.
To all that posted, thanks.

So I cleaned it out with baking soda and WD-40 AND I bought from one of our sponsors Mid-America they sold "hood Seals" for the leading edge of a C5 hood a really simple piece of rubber with a sticky side an after I cleaned the hood area, I put the seal on and connect my under-hood light. That was four years ago and I haven't had a problem with the under hood light since.

There is a manual but it is a 2002 book. I will compare it to the 2000 book at the site you linked to. Thanks.

P.S. The sun is out this morning and I plan to burn up as much of the crap 87 octane gas as possible and refill the tank with 93 octane premium for her winter nap.

As for the amount of performance loss with regular gas compared to premium, hard to say for sure, but it does suffer some. I've run 89 octane in mine before and really didn't notice any difference, but haven't gone to 87 octane and don't plan to.

Hi Guys,
Well, this is the first "TOY" I've ever owned that doesn't burn lots of gas really quick. Even with some nasty winds (close to 30 mph) the darn thing still managed a 27 mpg average. I drove for a couple of hours and still only burned about a quarter tank. I'll try tomorrow to use up some more and then fill it for the nap. I have the GoodYear run flats and they sure are loud on the freeway. There would be no conversation during a cruise. Anything else I should expect to be a contributor to the road noise on the highway?
