Gravitational waves are invisible. However, they are incredibly fast. They travel at the speed of light (186,000 miles per second). Gravitational waves squeeze and stretch anything in their path as they pass by.
bad bad bad. running your car low on oil can cause the engine to lock up and that means a rebuild. you should check your oil weekly along with other fluids. check your oil after your car has set for about 30 minutes or before you start it for the day. not doing this will give you unaccurate readings.
What color is engine oil leak? I think I'm being ripped off by my car dealer. I had the engine replaced about 2 years ago due to stupidity on a family members part. The whole engine needed to be repalced on a 99 Mustang due to not putting oil in it for over a year. So it gets replaced.
