Daiwa's Magseal oil technology has its upside and downside. The obvious benefit is that it provides advance sealing technology with minimal to zero friction. The downside is that it can sometimes become messy after long periods of use and that it's supposed to be maintenance free but it's not quite the case being maintenance free as the magseal oil tend to dry up over time
as seen with this other Certate.
Daiwa do not sell magseal oil to anyone as they are a proprietary technology. It is also true that you can't use any 'science kit' ferro fluid or mix-your-own-laser-printer-toner as replacement magseal oil due to unknown lubrication fluid as well as particle size used in those kit.
After rounds of testing done, I've managed to get my hands on suitable 'brew' as a magseal replacement oil. Tweaks were made to the 'brew' for a less messy affair and possibly longer service life.
This is the Daiwa Certate test mule which also had a messy magseal unit dried up for some time. It's even got a dead line roller bearing and replacement bearing arrived in time for a fix.

| New line roller bearing ready to be installed. Magseal oil dried up on this rough and noisy Certate. |
 |
| New bearing packed with marine grease for long life. |
 |
| Already dried up long ago, degreased and contact cleaned ready for a new injection of custom brew magseal oil. |
 |
| Dried up gap visible between the magnet unit and rotor collar. |
 |
| Custom brew magseal oil ready to be injected. |
 |
| Just a squirt. That's what she said. Custom brew quickly fills up the void. Excess can be seen outside the magnet. |
 |
| Messy affair no more as this custom brew is designed to stay put where it's supposed to be. |
 |
| Smooth as a new Daiwa Certate. |
This Certate's been fished for a while now and no reports of rough cranking nor messy affair around the magseal unit anymore.
In the event that you need to top up your magseal oil, do send me your reel for a special brew fix. You can find me at
Anglers Central.
