Contact the vendor of the alky system and ask them what liquids they recommend and how to set the system up. Second hand information on this issue can lead to system failure, engine damage, tuning problems, etc.
Dont assumme... it can cost you $$$$$.
Perfect example, run washer fluid through an older SMC system.. the pump will be toast in no time... run denatured with lube.. it may last 5+ years.
If your new to this.. start reading the message boards and copy what others are doing and having success... from that point.. make changes to the recipe and see if there is improvement. Its the easiest way.
