Who cares whether the oil is synthetic or mineral!!!!!!!!
The correct oil must meet or exceed ACEA E3 and/or MB228.3.
Many synthetic oils do NOT meet this specification which is basically from a
group of oils known as Super High Performance Diesel or SHPD for short. The
latest API CH4 and CI4 specifications also now meet this need. Running the
engine on this oil will ensure that even at 6000 mile intervals there should
be no particular wear issues until well into the third time round the clock.
Run a low detergent synthetic and you will run into problems due to sludge
unless changed very often.
Should you be particularly adventurous, and I would not recommend you or
anyone to do this, but you could well run up to 12000 miles or more with
synthetic or semi-synthetic oil that meets ACEA E4 [not E5] or/and mb228.5.
I tend to use the proper oil and change at every 5000 miles give or take.
The only reason for 5000 miles is for convenience, that is I can easily
remember the next oil change just by looking at the clock. This is no more
arbitrary than any other oil change interval, including the manufacturers
own.
