What is best Oil for Honda Civic 2003

I recently got my self for Honda Civic 2003.

I changed the oil from the oil shop.

He used Zic Oil. He charged me for "Zic x5 4L box", and used around 3.5L in car. Rest he put that box in my car.

Which is fine.

Thou i didnt knew anything about synthetic and semi senthetic etc.
I asked someone for best oil he said Zic A+ is best.

But somewhere i read fully senthetic oil is not good for old cars.

I heard from alot of people ZIC is good oil, but until recently i found that there are varients in ZIC oil and i should choose the right one.

As i have Suzuki GD110 and i always used 1L ZIC bottle but i never cared for what type it is.

But seems to be there are alot of varients for motor vehicle according to the ZIC website.
