I saw a comment which said if you run with no oil this would make a car sound and feel more revy and lively etc(though it wouldn't last very long). Is this true?
Personally when I've been low on oil and then added oil I've noticed the oil has improved the sound, revyness and liveliness, not the lack of it, though I could be mistaken. This is particularly when hitting vtec.
If it's true that no oil makes a car sound and feel more lively, revy etc, would thinner oil also do this and conversely would thicker oils make it feel less revy and more sluggish?
