UV Leak detection oil advice

[87creepin]

Has anyone had success using UV leak detection oil? I think it would be super handy but is it safe to use in engine oil/coolant, not just for testing ac systems?

Usually you can tell if engine oil or coolant is leaking, because it’s wet and not an invisible gas.

If the oil is clean it can be pretty damn hard to see where it's coming from though. Especially with how difficult it can be to clean all the residual oil out of all the little recesses it accumulates in, you sometimes can't tell if you're still looking at old oil or freshly leaked oil.

I've considered adding fluro to engine oil too but also dunno how it goes.

Working on 90s things, there's more hoses and places for stuff to leak. Plus less space so it would help to pinpoint where the leaks are.
