Another vote for Water Wetter.
Something that comes in a small bottle and makes the claim it makes, is automatically regarded as some sort of snake
oil.
I use two bottles of it with distilled water exclusively.. I gathered my own data, and tested different combinations on a engine stand.
Antifreeze and water
Antifreeze water and Water Wetter
Water only
Water and Water Wetter.
No questions about it. Stationery engine, same amount of airflow, same ambient temperatures. No variables.
Water Wetter score as much as 20 degrees of improvement. nay sayer suggested by the time I had gotten to testing it with Water Wetter the engine had sufficiently broken in and wasn't creating as much heat!.
I drained the stem once again, and tried all above combinations once again..
Same results.
before you dismiss Water Wetter as some sort of a gimmick, give it a try. It MUST be used with water only. Had no appreciable effect on the temperatures when added to my existing
Antifreeze/water solution in the engine.
