I was the first crew member to board the aircraft. I stowed my items; did my safety checks; walked to the rear of the aircraft; all okay. Shortly after the crew boarded; the two aft FAs (Flight Attendants) came forward. FA XX asked if we smelt anything. Simultaneously; I came out of the forward galley; I had already smelt the overwhelming smell of oil/diesel fumes.Three FAs deplaned immediately. I stumbled out the door. The smell of oil fumes triggered an asthma attack for me.My two flying partners felt sick. With the wheezing; shortness of breath; chest tightness; dizziness; nausea feeling; I sat on the jet bridge. My crew gave me an oxygen bottle from the aircraft; paramedics came to assist. Captain instructed the ground PC (Precondition) air to be shut off; and turn on the APU. A Ramp worker determined that the fumes seeped into the PC air from nearby construction. I was still sitting on the jet bridge with medics and staff when the passengers started to board. Captain XX postponed the boarding until I had officially deplaned.
Flight Attendant reported strong oil/diesel fumes during preflight; which resulted in physiological symptoms among the cabin crew.
