not related, I am using Total Quartz 9000

3000 is mineral oil
7000 is semi-synthetic
9000 is full synthetic

my opinion, either mineral oil with more frequent oil change or go full synthetic, no point going the middle path

how is your mileage and what type car and driving pattern

Manol macam API SP ACEA A3 B4 which is good standard provided they actually meet the standard.
