I've ran as much as 50-50 WWF/Meth and still used in on my windshield. Smell really NICE and didn't hurt the paint at all. It's not on there long enough, as it evaporates VERY fast!

 

 

Thats good to know, I wouldn't want to mess up my paint job.

 

How long does a full washer tank last before you hit low level? What kit and jet do you run. hhhmmmmmmm

 

With mine, I have a Devils Own kit that starts spraying at 4 psi and is full on at 8psi. I have a M10 (10gph) nozzle. I usually fill it up every tank of gas. I have had to fill it 3 times for one tank of gas though when I was towing hard and it was really windy. A day at the track will use about a quart or so I think.

 

I also run the #10 on an alky kit. I stay out of boost or under 3lbs pretty much on the street so a 5 gallon tank of meth lasts me near 4 months...

 

It lasts me a long time because I work away from home and the only time I get to drive my truck is when I'm on days off.
