Since your car is a 2002, and likely has several thousand miles, you should first clean your engine with an engine flush. If you just change the oil and put in a synthetic, the synthetic oil's better detergency will start cleaning your engine. The sludge and other things are just going to clog your filter and you will not get the longer oil life you will be expecting. Go to amsoil.com and look for their engine & transmission flush. You can also lookup the recommended oil and filters for your car. All synthetic oils are not the same, so don't make your choice on price. Amsoil was the first synthetic motor oil to receive API certification in 1972. They have more synthetic experience than any other company.

I agree this 5w/30 is fine for your car but you need to take into consideration of temp readings in your area. Higher temps in your area will affect your oils performance. Hotter? I would recommend heavier, such as 10w/ 30. If still uncertain check manual or under hood where their wiil be the suggested weight. If not there check the inside of the driver's side door panel. Oh ,synthetic is a fine choice or a synthetic additive is fine, because it helps the car's engine longevity on "cold starts" when all of your oil has drained into the pan. Say after a work shift, or overnight parking.Hope this helps.
