Redline Engine Break In Additive - Coolantant Additive

[Jking]

1. I have a FIST with 536 miles on it. Is Redline Engine Break In good for the FIST motors? Just did an oil and filter change with Motorcraft.

2. I ordered some Mishimoto coolant additive which I assume is like Water Wetter. Any problems with that in these motors?

Thanks

I've been running the Mishimoto additive, no problems. It does seem to cool down a hair quicker once you start moving.

Been running water wetter for about 500 miles. No problems.

the coolant additive I dont see being a problem but stay away from adding anything to the oil for the first 10,000. Just break the motor in over time let it do its thing.

Doesn't the manual specifically say not to use any break-in additives?
