About to do annual service normaly use 10w 40 semi synthetic but thinking fully synthetic
must be better however this all seems to have a lower viscosity rating  like 5w 30 or 0w 30
is fully synthetic allways better and is the different spec a problem with the older type engine of the g40.

use 10w/40 semi-synth.
