Aspire nautilus mini bvc coils losing flavor too soon

[brunotorres]

I bought an aspire nautilus mini with the bvc coil and, at first, it felt like it would be the perfect clearomizer for me. I was coming from an evod bcc, which started leaking juice constantly and a vision vivi nova that was a huge juice hog.
Anyways, the bvc vapes like a dream when the coil is brand new, but after just 4ml of juice or so (halo freedom, halo southern classic, halo Malibu, dekang usa mix, dekang tobacco and dekang Hill) it starts to lose flavor and produce less and less vapor.
I try to not let the tank get to less than .5ml before refilling, as it seems not to be a good idea to let it run too low.
I use an ego c twist 1300mAh and the 1.6ohm coil at 3.8v.
I tried rinsing the coil head to clean the wicking material (which is ceramic in my units, not cotton as it seems the new ones are) but it doesn't help.
I tried dry burning them after two days drying out the window, rinsing again, drying again for a couple of days and all I get is a burnt taste on the vapor.
I tried only rinsing (with cold and warm water), letting it dry and trying it to find it the same, flavorless.
The color of the juice seems to have no influence on the process, as I've used exclusively dark or light ones in an specific head to see if it'd make a difference.
It's a shame, because it's otherwise a perfect clearomizer, no leaks at all, nicely built, etc.
I can't change coils every other day, it'd be too costly.
Can anyone help me? Am I doing anything wrong? Can i recovery the coils with any other process?
Any help is appreciated.
Thanks.

I've noticed the flavor loss with certain juices, but not at 4ml. I usually just start "really" tasting my juices at 2 ml or so. The first tank I notice a weird flavor from the new coils. I wash them under water too, I think its just the wick/wire breaking in.

Mine start loosing flavor at about 20-25ml. I have a clear grape juice that I can get 30ml without any flavor loss. I usually have to change the coil on the grape because I am getting a burnt taste not because of flavor loss.

Now the vanilla custard is a different story. I only get about 20ml before I notice flavor loss. The coil doesn't look to gunked, its more the wick/filler that is the problem. It turns a nasty blackish brown color and doesn't seem to wick very well. The draw becomes quite restrictive too.

Flavor is usually not a issue with the Nautilus mini, they are known for their good flavor/vapor. Are your juices dark in color or more clearish? Are the heads you are using the new (Large hole) or old style (smaller hole)? I notice I get better flavor from the newer larger hole BVC.

I use clear and dark juices. About the heads, all I know is they're 1.6ohms, bvc, and I checked they're genuine. They have the ceramic wicking material.
The hole you mention is the juice sucking hole in the bottom or the one on the top where the vapor comes from?

What ratio PG/VG are you vaping? Also, when I clean coils I'll boil them for a minute in the microwave, soak them in alcohol for a couple hours and then boil them for another minute. Dry burn and blow out the water and it's like having a brand new coil.
