I checked my oil when my trip odometer was at 2975... It had a good level, but was getting dark. I planned to changed it at 4000. I checked my oil today at 3456, seriously, a funny number, but real... Engine had been off for a couple hours, parked on level ground. Pulled out dipstick, wiped away oil. Inserted, waited 5 seconds, removed and checked. Didnt see any oil. wiped with white shirt, very, very faint residue. There was clearly no/very little oil in the engine. I stupidly decided that i should try checking with the engine on... i now realize this was dumb because if there is any oil at all, it is going to be thrown around, and read extremely high, hence the reason you wipe the stick before checking. I opened the cap on the valve cover and could see oil spirting with every engine stroke. I figured this was normal and relaxed. It then occured to me that it may be spirting because oil is being pumped, and takes a bit to settle back to the pump, hence it is low. I added a quart, and it is clearly visible on the dipstick.
With such a low level, i am surprised that the engine hadnt seized yet... I somewhat abuse the car, at least every other day i hit 107mph(speed governor is set at). I use engine braking whenever possible. In my effort to find the maximum speed i can be at for each gear, i ran the rpms just slightly in the red, litterally, assuming the gauge reacts quick, it was only about 50rpm in the red...
Is there some reason why all my oil dissapeared? I havent noticed any oil spots where i park, but will now be keeping a close eye on it...
I was doing a variety of basic maintenance and diagnostic procedures which included attaching a vacuum gauge, and it read perfect, a steady 20in/hg. Decreased under hard acceleration, increased under deceleration, held steady with slow increase in engine speed.
Thoughts on what happened, how much damage i did to the engine?
Edit:Oil light never came on, i am still getting 42MPG, exhaust smells "normal"(a little lean, but i know the engine runs lean, and its normal for it) Has been running fine. Occasionally i lose power, abruptly, and short-lived, I sometimes have to downshift to maintain speed up a moderate hill. (Fuel levels are fine, and this happened even before the oil issue(IE before 2975, the last known good point))
