Is it a good idea to move from Synthetic oil to normal oil ?

On my 2000 Accord, I started adding 'Bars Main Seal Repair' oil-additive to my oil at every oil change starting around 90K miles and it never "lost" oil again (sold it near 200K miles). Before that, it was using/losing at least a quart or so per oil change cycle (not sure where it went, but I never had any oil leaks on the ground under car or anything like that). It's an awesome product, and solved all my oil "loss" issues on my Accord for the 100K or so miles that I used it.

It was burning the oil but now with catalytic converters, the oil was being incinerated by the cat before it could appear as blue smoke out the tailpipe. IF you follow a car with hundreds of thousands of miles on it when it has just been started, you will see a puff of blue smoke every time the trans shifts. That's because the cat hasn't heated up yet. Once its up to temp...no more blue smoke.
