MoPNG response to concerns on 20% blending (PRID 2155558)

Applies to

MoPNG on E20 and the fleet: for some manufacturers vehicles have been E20 compatible from as far back as 2009; no issues across drivability, startability, metal and plastic compatibility under BIS/AIS standards; on certain older vehicles some rubber parts/gaskets may need earlier replacement, inexpensive and routine. [regulatory-date framing removed 2026-07-23: not present in PRID 2155558; basis is the fleet clarification per record notes.]
