Welcome to the community.
Yes, dealerships should have the supercharger oil, you would need two bottles and they run about $8 per bottle. One thing you can do to get the oil out is contact Farnsworth (a member here) and see if he has any of his siphons left.
If not, go to some place like walmart and see if they have those syringe type devices used in 2-cycle oil mixing. It looks like a syringe with a tube attached. It will work fine for the job. I dont know what they cost there, but check with Farnsworth, he may have them cheaper.
