Hi guys! Just wanna ask your opinions regarding my problem. I know there are lots of threads regarding this but I can't find one with the exact same scenario as mine. So here it goes...

I only use my car 3 times a week (ave. of 35 - 40km back and forth), and sometimes my reservoir is already drained after a day, sometimes after two or three days. I think I have a leak or something so I did some troubleshooting (I got the techniques here in tsikot.com hehe!)

1. Checked under the car for some leaks, didn't see any.
2. Refilled the reservoir this morning, after I got home from work I checked it again. The coolant level remained the same.

I don't experience any overheating issues, it's just that I think it's not normal?

BTW my ride is 95 Civic ESi.

Sorry for the long post! Hope you could give me some inputs!
