No it wont make any difference. Use what you like.
BTW the main reason you change the oil is because of contamination in the oil from the engine. It makes no difference whether the oil is regular oil or synthetic. Although technically the synthetic will hold together and lubricate longer than regular.
So you want to be very suspicious of people claiming you can leave synthetic oil in for longer drain intervals than the manufacturer recommends.
One thing synthetic oil DOES do is flow better than regular oil at temperatures below say 20 degrees F. So if you live where its below zero a lot it makes sense to use it.
Which in Bangladesh I don't suppose it does!
