I had visited my nearest Honda 3s dealership and they don't have hcf-2 gear oil(3.5L) and they are only offering cvtf gear oil(1L). Where as in Honda's car manual it says only use Honda hcf-2 gear oil with quantity of 3.5L. Honda's other dealership have hcf-2 gear oil(3.5L), but they are quite far from me. Is it going to cuase harm using cvtf? Is there any difference between these two different oils? If yes, than which one is better?
