Brother,
I suggest to use PTT Perform 5/40
This oil is really outclass and I am using it since more than quarter. Car is running as smooth as silk.
Its not expensive like Mobil1 or Liqui Moly, etc. But a bit expensive than ZIC.
Why Performa?
Because for the time being, its being imported directly and sell in Pak. market. Not yet re-packing has been started here.
Its from Thailand and oil is really outclass. Am sure you'll like it. But always use Leepon's air & oil filters. These are best with every oil change.
Change this oil after 5K for sure. No-problem at all.
If you like this oil, then next time use their Super Synthetic 0/40. It’s another outclass oil and even better than ZIC XQ.
Cheers & LOVE.
