answer:Depends. Manual or Automatic? If you do have a dipstick: Park your car on level ground and start the engine, leaving the gear in neutral or park. Wait for the engine to warm up. Unless your owner's manual directs otherwise, allow the engine to continue running throughout this procedure. If the owners manual suggests otherwise, would certainly follow that criteria. If you do not have the owners manual, you can run a search on google and find the manual in .PDF format.
