true he does but you are not bound to buy those
look around in his shop and pick what you think is best
One of the best i guess is LiquiMoly in 0w20 but its very costly now
others are Meguin which is also Germany based
Totachi oil is also introduced in out market sometime ago
Molly Green is also available at some shops
Edit:
from personal experience its fine to use an ok oil and change by 5k then buying 2x costly oil and change by 10k or so
i used LM 5w30 in my Move for 7k or so and it was still fine but in the back of my mind i was afraid of oil filter condition etc so now in Honda City i use Total 5w30 which is imported from Singapore(not local blend which is sold by Honda too) and change at 5k for piece of mind
also you never know when imported oils will stop coming here or become more costly
