Is the plastic quality of Changan Alsvin’s fuel cap substandard for Pakistan’s heat and road conditions?

In cities like Karachi, Multan, o r Quetta, intense summer heat could cause expansion o r brittleness. Could this be a reason for cracking o r sealing problems?

Yes, there is substantial user feedback suggesting that the plastic quality of Alsvin’s fuel cap is not well-suited to the extreme temperatures and UV exposure in cities like Karachi, Multan, o r Quetta. Prolonged exposure to high heat can cause the cap to expand, warp, o r become brittle, especially if inferior plastic is used. These thermal stresses can lead to cracks o r loss of threading, reducing the cap’s sealing ability. The combination of hot weather and engine bay heat exacerbates this issue, making it more common in southern and interior parts of Pakistan.
