SIAM Withdraws E20 Fuel-Quality Communication; Figures Need Verification

SIAM has withdrawn an earlier communication concerning E20 fuel quality and said the cited figures require authentication. The withdrawal should not be presented as a confirmed finding about fuel quality.

What SIAM clarified

How motorists should read the update

The safe conclusion is narrow: a communication was withdrawn because the cited numbers were not ready to be treated as authenticated findings. It does not prove that every concern about E20 petrol is either confirmed or disproved.

Owners should continue to follow their vehicle manufacturer's fuel-compatibility guidance and official government notifications, especially for older vehicles whose materials or calibration may differ.

Practical checks

• Check the owner's manual or manufacturer notice for E20 compatibility.

• Do not treat withdrawn or unauthenticated figures as established test results.

• Document any drivability issue and seek an authorised service diagnosis.

• Watch for authenticated technical data or formal regulatory guidance.
