Squeaky oven door - what oil would you use?

[walkbesideme]

I've cleaned my over for the first time in a year with Mr Muscle. Now the door gives off a very loud irritating squeak. Not sure how it happened, but wish I hadn't bothered!

Anyway, what oil would you use to stop it. I only ask as I'm worried about flammability - or am I being over paranoid.

Thank you for your answers.

Castrol, bearing grease, (for cars) will withstand heat. Ask a friend for a smear rather than buy a pot if you can!

Thank you Chatelaine - I knew someone on here would know. I love Mumsnet.
