Default Windshield washer fluid..

For anyone out there using a 50/50 water/methanol mixture, Walgreen has a sale on -20*Peak windshield washer/deicer fluid. Price is 2/$3.00 limited to 4 bottles.

Personally, I wouldn't use wiper fluid. Just buy methanol and mix it with 50 percent distilled water. Keep all the other crap out of your engine. It will be a little more expensive, but not much unless you are always in boost - in which case you are spending a fortune on fuel anyway so the small incremental cost won't be much of a difference.

Only reason I would buy wiper fluid would be as a backup in case you run out of meth and you need it as a safety net.

Just my 2 cents

Correct, I'm not in boost often. I thought if this was comparable to the 50% mix It would save me the trouble of mixing the stuff. Keeping a bottle of the washer fluid as back up would be a good idea.
Thanks,

I thought -20 windshield washer fluid was 40% methanol. I run 75% methanol in my tank for injection.

For what it's worth.....
Personnally, over the years I have had issues (mostly clogging) with store bought premixed windshield washer fluids.
Since the C4 years I've used GM's Optikleen and mix it myself w/ distilled water in all makes and models of vehicles w/ no issues.

When does your methanol spray come on?

Mine doesn't since I never ended up going boost and it won't work naturally aspirated (despite spending nearly $900 in parts and labor trying - based on the manufacturer's receommendations).

You should be able to get a progressive controller for it. That's what I bought for mine. Too bad I can't use it and they won't take it back!

Depending on what brand you have, I'll gladly give you a good deal on mine. It's brand new!
