winterizing meth kit?
I was wondering if anyone drains the meth out of there systems for the winter? I have heard of draining and filling it up with washer fluid to keep pump seals from drying out? Any opinions. Thanks.

You can put in 1/2 gallon.. then push the test button until blue fluid comes out of the hose. At that time, the pump is sitting in washer fluid not 100%.
If you don't push the test button.. pump is sitting on 100% and all the extra work was done in vain.
Come spring.. same procedure.. drain washer fluid.. fill the tank with meth.. run it till it gets clearer. Go from there.

Help longevity of seals within the pump. The meth don't need it.. its for pump health.
I use the salt water analogy... why keep your boat sitting in saltwater for months.. having the option to let it sit in a lot less aggressive chemical can only be helpful.

My meth system has been stored in sub zero weather full for probably 7-8 years....should I be worried?

My car sits on a trailer, gets driven 1-2 times a month.. and gets driven hard. Its the worse as it sits for extended periods without use.
After performing pressure tests on the system, at the 1 year, 2 year mark, 3 year.. typically by the time it gets to 3 years the seals will leak at full output. Meaning pressure in excess of 100-120 PSI. So every couple years I simply refresh the pump with new seals.
Pump motors have a 1500 hr rating. You'll never get to that.
If the car is not tuned where it needs it.. no worries.. keep using until the leak bothers you. Car like mine that makes 1200 RWHP.. i'm on it and not risking engine damage over 80 in parts.
Like an oil change.. I change mine every 2 minutes of WOT
Some wait 10k miles.. or until the rod bearings start making sounds

Yes if you expect optimum performance. Seals will degrade over time. Its not a motor issue but simply methanol is a tough chemical.
