I did changed to Shopee Mall engine oil which they advertised with PAO + Ester. If it indeed clean agressively (due to PAO + Ester), I will repeat this.
Is this bold parts are similar to Shell Helix Malaysia version where they advertised it as "Untuk Pasaran Malaysia" where most known no technical changes for the oil vs other region.

For analysis parts, hopefully there are one who done it on the Petrol version. Cz some brand advertised their Fuel are the bestest vs others, some mentioned put double additive vs recommended, while some offer the best for their 97 Ron.
