Plugs look good.
I prefer Laser Iridium thou and change them every 75k km (47k mi), so second change on a 10 y.o. car.
I had original factory coil fail on cyl 2 recently (at 100k miles) and would like to report SKP coils from RA are not only cheap but looked high quality and work great.
Imho, start changing oil every 4k miles, I saw big diff in used oil between after 4k and after 5k miles.
To keep fuel pump, fuel filter, fuel lines and injectors clean (of gunk) - use Gumout Regane Complete or Regane High Mileage - those two have high % of PEA and are cheap at WM.
I have an older Schumacher charger with buttons to select reg/AGM/Gel and iirc 4A/12A to choose from, it's way over 10y.o. and still works. It has a display to show V or % of charge.
Euro LX oil is both C2 (fuel economy) and MB 229.52 (LSPI protection); unless someone wants an oil thinner than 30 weight only then PUP may make sense, I'd prolly go with VW 508 oil thou.
