I have erected false walls using osb boards on the face of plastered brick wall to accommodate some photo frames and decorative items. Total surface area is 8'×8'.
My intention is to paint the osb board using high gloss white paint. This paint requires primer to be painted first.
Since osb naturally have tiny holes and voids, i think the primer must be diluted for easy flowing into those voids and gaps.
To keep the cost low, can i use petrol (gasoline) for thinning the primer? The paint thinner cost 6 times higher than the petrol in Malaysia.
Pls advice.

You should use mineral spirits or mythle-hydride to dilute oil based paints. I don't really think that diluting the primer is the best solution though. It would be best to lay it on thick with a heavily padded roller and then back roll it out. Primers job is to seal and adhere. Thinning it will only prevent it from doing its job.
