Try out this oil which was going very cheap in local store.

having doubt on the quality.so decided to sent for a UOA.

turn out the TBN is still healthy after 3125miles(5k km) which is the dealership recommended oil change period.

Your wear metals were low becaue you used 4.3 quarts of make-up oil. This seems excessively high give the few miles you have on your car. Did you actually use this much make up oil or is the capacity of your crankcase?
 
the makeup-oil amt show were actualy the capacity of the crankcase.

it a 2000cc inline-4 engine.

and has travel 5k km ( 3125 miles).
 
Another boring MZR UOA. Mazda hit a home run with that engine. In the USA, we use 5w20 oil.

Its good to know that the engine is oil weight-proof.

Definitely extend the interval to 7.5km or 10km!

Who cares what the dealership recommends...I'd go by the manufacturer recommendations for the oil change interval. The dealer probably recommends 3,000 mile OCI's just to get more money out of your wallet (just like all the fast-lube places do).
