Using C3 Oil in C2 Car

[Jetronic]

This is a very interesting website! Great for comparisons. It does however show that there is no improvement for wear on C3 over C2 which seems odd to me considering what I've read.

The fuel economy does as expected going from C2 to C3.

The car is a Honda Civic 1.6 I-DTEC. 112hp. Probably going to be remapped though in the future so I will want to keep it well maintained.

You can't use that tool to compare 2 specs against each other, but rather to see where the focus in a particular spec is placed. C2 has fuel economy focus that C3 doesn't have as you found
