Servicing advice

I have only owned my NB 2.5 for 1 year (Newbie).  It’s service history gets a bit flakey for a few years just before I got it.

It’s 16 years old but only done 46k miles.

I would like to do a basic service myself, but the oil looks a bit dark.

Does anyone know of a reputable mechanic/garage to advise fairly in the Formby, Liverpool L37 area.

Thanks in advance for help/advise!

My brothers garage is in Maghull, not too far, I’d say he was reputable
