I just checked washer fluid on my 2016 Fit for the first time. I can easily see the reservoir with the remaining fluid in the bottom. I can't, however, seem to locate any max or min fill lines anywhere. How full should I go?

I'm sure there's an easy answer out there, but I can't find any descriptions or pictures of max fill after an hour of searching the web. Thanks!

 

I just fill it until about an inch from the top.

 

yah, just fill it to the top give it like an inch or so from the cap.

 

Thanks for the replies. I still wonder why they don't just put a line on there for guys like me who don't know.

 

its not u, I too was scratching my head at first and I consider myself a car guy.

 

I'm relatively sure you can't really go wrong.
The first time I filled my reservoir I accidentally overfilled it.
About 15 seconds of usage lowered the level enough to NOT make a difference.

I'm NOT recommending overfilling...but if you stop an inch or two before the top, you'll be fine. The only thing to know is that when it close, the filler neck narrows and it fills up quickly.

 

I fill bug juice to the top most of the time.
On some cars I might turn the gallon jug upside down and stuff it into the fill tube just so I don't have to hold the gallon jug up and pour it (painfully) slow.
I let that stuff splash, it isn't going to hurt anything.

I'll use washer fluid to rinse off spilled antifreeze....because a jug of bug juice is handier than the garden hose.

 

Imagine it is a a cup of coffee without any lines on the cup. When it runs out, fill it up. How high to fill it is up to you. If you want to refill it before it is empty that is also OK.

 

It doesn't have any max and min fill lines because the car operation doesn't depend on the level of the washer fluid; you won't hurt anything by overfilling or underfilling, like you can with transmission fluid, engine oil, etc. It's no different from the gas tank in that regard; so long as you are somewhere above completely empty, there's gas (or washer fluid). I don't think I've ever seen a vehicle with a maximum marking for washer fluid. The nicest ones I've owned had a reservoir that was a little bigger than a gallon so it was possible to add a full jug at once and not have to worry about having leftovers. The Fit's isn't quite that large.

On my other vehicle, which uses a ford E-series van chassis, you can't even see the level in the tank at all. About all that you can do is listen as it's filling for the (rather long) tube from the fill cap to the actual tank to start getting full.

 

Interesting threat. I have just purchased a 10 liters(2.64gal) in costco. The water deposit was empty so I refill it until full.

The washer fluid ingredients is important. As a marketing guy I never read etiquetes or what does guy like me write. I go straight to the ingredients list. Based in this I buy or not a washer fluid. This have several stuff like the kind of water that is Deionized water Organic solvents and so on. It was pretty expensive for what it is but based in the ingredients it is good buy. You should not put hard water, amonia, vinager or alcohol based washer fluid. this will corrode or make calcium deposit that will make your pump water and cables not work optimal.
Also you might need isopropyl alcohol if your climate is 0C(32F) if not it might freeze.

Am I the only geek guy who put so much attention to details?

 

My canadian tank takes 4 quarts/liters based on the manual. Fill-er up straight to the top.

 

Canadian Fits have a larger washer reservoir than US spec cars. Ours only hold a bit under 2 quarts.
