I've done many clutches myself, including Hondas; I know exactly how they work first hand. Don't be a jackass, people are just trying to help. I have used regular engine oil as well, and it worked fine.

I had a cracked pressure plate and I was still able to drive the car to a shop, so no a worn/damaged clutch doesn't mean it won't shift.

There is a much easier way to test the clutch while parked...with your foot on the brake, put it in second gear and let the clutch out without giving it any gas - the car should stumble or die - if it doesn't before you get the pedal out most of the way your clutch is slipping and may be worn out.

I got 170K on the clutch on my 240, but it was WAY worn when I pulled it out of the car.
