Installation of Revised Fuel Placards
Bulletin No. 2000-1
Revision No. 1
Date: March 1, 2000
Revised: January 20, 2005
APPLICABILTY: This Service Bulletin applies to all aircraft previously modified in accordance with automotive fuel Supplemental Type Certificates (STCs) supplied by EAA Aviation Foundation or Experimental Aircraft Association, Inc. See attached list of aircraft models approved under EAA automotive gasoline STCs. This revision supersedes Service Bulletin 2000-1, dated March 1, 2000. Revision reflects change of ownership of STCs from EAA Aviation Foundation to Experimental Aircraft Association, Inc. and previous EAA Foundation consolidation of Autofuel STCs into two STCs specified as SA01944CH and SE01943CH.
REASON: A new aviation fuel known as 82UL has been approved in the United States. Due to the possibility of 82 UL having a higher volatility than previous aviation fuels and because of other differences from previous aviation fuels, it has been determined that some method of airframe re-certification was needed. Since, among many other things, volatility testing was conducted as an integral part of automotive gasoline STC testing and 82UL has a lower volatility requirement than automotive gasoline, the FAA has approved the use of 82UL aviation gasoline in aircraft which hold an Automotive Gasoline STC.
However, 82UL is not suitable for every airplane which utilizes an automotive gasoline STC. The octane of 82UL is more than adequate for use in engines that were originally rated on 80/87 or lower octane fuel. EAA STCs only cover engines that were certificated to 80/87 grade or lower gasoline. However, STCs issued for some higher compression engines require the use of 91 octane at a minimum. Airplanes so equipped are NOT ELIGIBLE for the use of 82UL. Installation of revised fuel placards is intended to clarify the minimum fuel octane requirement of each airplane modified to use automotive fuel and prevent the introduction of 82 UL into higher compression engines.
COMPLIANCE: No later than August 1, 2000, replace previously installed fuel placards with revised fuel placards which specifically state:
THIS AIRCRAFT IS APPROVED TO USE THE
FOLLOWING UNLEADED GASOLINES:
Automotive Gasoline 87 Min. AKI
Per ASTM Spec. D-4814
82 UL Aviation Gasoline
Per ASTM Spec. D-6227 (Color Purple)
DO NOT USE AUTOMOTIVE GASOLINE CONTAINING ALCOHOL

AVAILABILITY: Revised placards are available from the Experimental Aircraft Association, Inc. 800-236-4800 or STC@eaa.org.
WEIGHT & BALANCE: No change to weight and balance.
INSTRUCTIONS: Remove and replace existing fuel placards with revised placards in accordance with this Service Bulletin.
