the driver gets addicted to staying away from a repair bill
yoou can stop giving the engine a 'hit' but then you'd have to fix it
in oz my camper ran mint until we went south where it was cold as fuck, wouldnt start for shit but an aussie dude on the camp came over with a can of deoderant and it starter on that (i do know why) soon as were were north again it was fine
was i fuck gonna go fix it so i bought some aerosol lube and started on that if i needed
