Will a regular blacklight show dye?

Trying to chase down a little leak. I now have dye in my engine oil. Will a regular blacklight show it or do I need a UV light?

"Blacklight" is the nickname for UV so same-oh same-oh. Not sure if oil lights up much under UV though. Maybe someone else can answer that one.

EDIT TO ADD: The dye... is it something you added just so the oil would light up? If so, then I bet you're onto a good tool.

Bring 'em home or send us back!!

I thought there was a difference between a blacklight and UV light but I really don't know.

I have a little leak ive been chasing on this bike and its driving me nuts. I need to see if its Engine Oil or Primary fluid leaking so I can narrow my search on locating the leak. I added the Dye into the engine oil last night, and will ride the bike today. When I get my usual few drips on a piece of white cardboard, I will use the blacklight to see if it "glows." If it does not, then I can eliminate anything that will leak engine oil and I will put dye in The primary to be sure.

Come on (motto) master of the obvious, does the dye (UV light for fluorescent type penetrants) light my itself in blacklight? Bright white light for visible dye penetrants. Aerospace dye pents are water based non-toxic.....also used as location markers. so if green blacklight if red brightwhite, hope whatever you have works for you

Wiki says it better than I did Kyle so I still say you're on the right track doing exactly what you're doing. Good luck finding the culprit.

I never realized there was so much to a blacklight haha. From what I understand it will work fine though! I cant wait to figure this leak out its been very expensive so far with no results.
