Why must you stick with synthetic? What happens if you don't?

synthectic motor oil just lessens the amount of friction,a dn controls the heat better then most motor oils. motors perform best with the least amount of friction and heat, thats why most people prefer synthectic oils.

i personaly swear by Royal Purple synthectic oil. you can feel the difference when you change from another motor oil to that stuff.

pretty much if your car is running fine just inspect it.. but if it was me i wouldnt change it until you have to why waste the money if you dont have to.. for timing belt and water pump its good to change but its alot of money if you dont do it yourself. check for cracks on the belt if its fine you should be ok
