Use the engine oil spec required for your car's engine. Eto kasi ang fully tested ng manufacturer sa car engine nila.

For example sa Mazda Skyactiv direct inject gas fuel engine, required talaga na ACEA A3/A5 Euro blend or API SN / ACEA C3. Using other oil spec may lead to some side effects, e.g. oil gunk deposit build up due to incorrect viscosity.
