I'd be a little worried about sparks myself,[course maybe cause I've been on fire a few times],you could run water in it,,use a angle grinder,,they sell different thicknesses of disks,,you want a thinner one,maybe not real thin cutting disk but maybe 1/8th thick one,,might need 4-5,,,welding supply places sell them.
I'm in the business, and i cut up oil tanks daily. I use a recip saw. Works well.
You do not need to worry about sparks. Oil is combustible, not flammable.
