According to the TSB that is what the spec. To be honest we have used both....
The Motorcraft is more expensive than what Suzuki would give us in warranty work.
However after a recent message from ford about All Make All Models coolants (silicate free formula not tested and verified for proper protection) we have stopped using it and are solely on Motorcraft again.
Motorcraft Gold is a great product and will serve you very VERY well.
