Pso has a reputation issue.
If they clearly reveal what oil theyâre importing and what additive blend theyâre using I will be less skeptical of them.
Otherwise no way I will ever trust their oil. Personal opinion.
Why on earth I will not go for global giants in automotive oils that are offering great lubes locally in competitive pricing?
Unless PSO is selling API SP for more than half the price of Shell or Havoline API SP oil 4L I ainât ever going for it personally.
Not worth risking my engine.
