This should prevent the cylinder bores from rusting. I sometimes just spray about two teaspoons of oil into the cylinders via the spark plug holes. But the biggest danger seems to be oil starvation of the crankshaft bearings, and especially on B20 and B30 engines, the camshaft bearings. This will not be cured by pouring some oil into the cylinders. Wheel bearing grease will go off when left stationary so renewing it when the car leaves it's hiding place may prevent premature wheel bearing failure.
Tyres also suffer from long term storage of the car.
Ideally you should replace the wheels by some old ones and store the good ones. If you just leave the car standing like that the result will be a heavy rumble and vibration from the wheels. Another problem is with the petrol that will be almost unusable after two or even one year. In that case you will have to remove the old petrol and replace it with fresh one. Quite a hassle I would say.
