Hi Bro ,
This M1 ESP 5W30 is a mid-SaPS oil of rather powerful specs in ACEA C3 MB 229.51, 229.52 ; VW 50400 VW 50700 etc .
In Europe , OEMs' MB and VW recommend this oil for 30,000 km oil change intervals in appropriate MB/VW engines .
There is absence of darkened centre zone in this 7800 km used oil , which is good news .
There is also absence of darkened aureole zone/perimeter ring indicating absence of agglomeration of combustion contanminants and top form detergency and dispersancy performance .
I consider the whole of diffusion zone as lightly contaminated with dirts with huge capacity for further absorbing additional amount of dirts during further usage .
Generally the amount of water moisture present is very mild and on the low side , judging by the not so obvious jagged external edge which is not darkened anyway .
However , there is some slight indication of fuel dilution from the very slight translucent halo annulus external to the outermost zone which is harmless for now .
Overall , this used ESP is fit for further service IMHO beyond 7800 km .
Thanks bro Zeng. I will continue to use it until 10k then do another blotter testThis M1 ESP 5W30 is a mid-SaPS oil of rather powerful specs in ACEA C3 MB 229.51, 229.52 ; VW 50400 VW 50700 etc .
