kako za što,
jer nije svaka plastika - 'plastika'

uostalome, skuteri i auti(u zadnjih cca 10 god) imaju rezervoare od plastike, a ne od metala
a i oni karnisteri za gorivo od 5L su od plastike,
njih benzin ne otapa definitivno.

Citiraj:
Two technologies are used to make fuel tanks for automobiles:
  • Plastic High density polyethylene (HDPE) fuel tanks produced through blow moulding. This technology is increasingly used as it now shows its capacity to obtain very low emissions of fuel (see Partial zero-emissions vehicle). HDPE can also allow for complex shapes to be formed, this means the tank to be mounted directly over the rear axle, saving space and improving crash safety. Initially there were concerns over the low fracture toughness of HDPE, when compared to steel or aluminium. Concern for safety and long term ability to function should be considered and monitored
  • Metal (steel or aluminium) fuel tanks obtained by welding of stamped sheets. Although this technology is very good in limiting fuel emissions, it tends to be less competitive and thus less on the market.
