    Votre twingo roule à 100% à l'éthanol ?

    L'avez vous modifiée ou est ce que ce moteur est prévu d'origine pour rouler 100ù éthanol ?

    Bonjour,

    J'ai fait installer un boitier éthanol au tout début (avant de récupérer ma voiture) mais que j'ai retiré volontairement un beau jour, juste pour tester. Je roule depuis ce moment sans rien du tout (boitier complètement débranché), moteur d'origine, non modifié et avec 100% d'E85 en toutes saisons. Je vous invite à regarder le wiki qui rentre plus en détails sur de nombreux points: Renault Twingo III Phase 1 (2014-2019)

    • Torque the new spark plug using a 14mm spark plug socket at 24 N.m.

    • Verify and ajust the spark plug gap to the considered model's spec if necessary.

    • The RTA (French Revue Technique Automobile) and spark plug manufacturers advise not to grease the spark plug's thread.

    • Do not modify an used spark plug's gap.
