Hi @Ian4,
Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you join us.
Yes, most modern paint sprayers can be used with oil-based paints, but it is still worth verifying with the manufacturer of the specific paint sprayer if this is possible.
Do you have a specific paint sprayer in mind?
The product manual will likely indicate how to go about spraying oil-based paint using their sprayer. You may need to use a thinning product such as DIGGERS All Purpose Thinner to thin the paint and allow it to be sprayed.
Please remember to wear personal protective equipment, including a mask or respirator when spraying paint.
You might like to check out How to paint like a professional for some guidance on how to achieve the best result possible.
Let me know if you have any further questions.
