My ZL has very few miles on it due to lack of snow here in WI. My 2002 Pantera 600 EFI calls for a 100-1 mix for break-in. The manual for the ZL EFI states engine damage will occur if mix (100-1) gas is used during break-in. I find it odd that the same basic engine on the 2 sleds has such a difference in break-in fuel. I feel more comfortable using the 100-1 mix during break-in.

What is your recommendation?

Thanks !!!
