High quality Castrol oil
I always use Castro oil in my vehicles from my motorbike to my truck. Have never changed transmission oil before so bought this and what a difference. For reference I have an old Mitsubishi l200 pickup truck so requires regular maintenance Oil quality is fantastic and has not let me down. For ease I also purchased a syringe to help refill the gear box and transfer case which made it much easier. I would never not use Castrol oil

Si tienes un audi a4 b6 de 5 velocidades (awx) y quieres sustituir la valvulina de la caja de cambios, esto es lo más parecido al lubricante original que vas a encontrar en el mercado. Probé otros antes de marcas reconocidas y los tuve que sustituir por el tacto duro y brusco de la palanca de cambios. Con este aceite esos problemas han desaparecido, las marchas entran suaves y sin forzar, tanto en frío como en caliente. Para hacer el cambio se necesitan 3 botes de un litro, aunque siempre sobra algo.
