Try urban decay de-slick. Or sprays of that nature. You spray them on before and/or after make up to stop them getting oily.
Also a large part of how your make up sits is your skin care routine. You can have a Lancome or Bobbi Brown foundation worth £50 but if you're not using the right skin care it won't look good. If you use YouTube I'm sure you'll find oily skincare routines to help you - MissGlamorazzi I know has incredibly oily skin, so check out her advice.
Very important though, don't avoid all oils in products you use, because that will starve your skin of oils and you will produce more to compensate for that. Don't be scared of trying everything.1
