Grid dip meter

Does anyone know where I might be able to get a grid dip meter that goes
down to 100KHz?  I used a borrowed one a long time ago for coil tuning, but
haven't been able to find one since which covers the normal Tesla coil

'car engine oil' has got a lot of additives which make it unsuitable 
for caps. You could use pure mineral oil or transformer oil (without 
PCBs of course).
