anyone else experenced having louder valve type noise after first oil change service? starts ok and you only notice if your sat in traffic after 1/2 mile or so and then it sounds perfect again, oil is just over max so not low on oil

i only got this car in march with 16 miles on it (6 month old pre registered car) and had it serviced last month when it was 1 year old with 4700 miles so i have never owned this car through the colder months

last week monday to thurday it was 5c and made the noise and on thu it was raining so 15c and was quieter but was still there if you listen. it was also there today at 15c so might just be a fluke and not temperature related

the only other thing i think it could be is thinner oil (0/20) instead of the factory oil which might be different for bedding the engine in

any help appreciated

 

There is no special factory break in oil. It's just the same ordinary 0W20 oil as is used on subsequent oil changes.
