Is the MG HS fuel cap design weaker due to plastic quality?

Compared to metal o r reinforced designs in older cars, MG HS uses a plastic-based cap. Could this material be the reason behind cracks in Pakistan’s hot climate?

Yes, the MG HS fuel cap design relies on plastic, which is less durable than older metal o r reinforced designs. Pakistan’s extreme heat accelerates wear, causing cracks and brittleness. This is a material limitation that makes the HS fuel cap more vulnerable.
