- ignition engine, then the test fuel used shall be consistent with the fuel specifications as outlined in the "California Exhaust Emission Standards and Test Procedur es for 2001 and Subsequent Model Passenger Cars, Light

- Duty Trucks, and Medium

- Duty Vehicles," as of January 1, 2006 (last amended August 4, 2005) incorporated by reference in Section 1961(d), Title 13, CCR). The California fuel specifications are contain ed in the California Code of Regulations, Title 13, Chapter 5, Article 1, Sections 2260

- 2272. If the engine is tested using the U.S. EPA test fuel, consistent with the fuel specifications as outlined in Title 40 Code of Federal Register, Part 1065, subpar t H, the manufacturer shall demonstrate that the emission test results complies with these Test Procedures.

(B) For 2013

- 2019 model

- year gasoline

- fueled, large spark

- ignition engines, the manufacturer has the option to use the fuel specified in (e)(2)(C)

. (C) For 2020 and later gasoline

- fueled, large spark

- ignition engines: The certification test fuel for exhaust emission testing must be consistent with the fuel specifications as outlined in title 13, section 1961.2 and the “ California 2015 and Subsequent Model Criteria Pollutant Exhaust Emission Standards and Test Procedures and 2017 and Subsequent Model Greenhouse Gas Exhaust Emission Standards and Test Procedures for Passenger Cars, Light

- Duty Trucks, and Medium

- Duty Vehicles, ” adopted March 22, 2012

, and incorporated by reference herein. The test fuel specifications should remain consistent from batch to batch. Optionally, manufacturers may use other renewable fuel blends under this paragraph that have been certified by ARB as yielding test results e quivalent, or more stringent than, those resulting from the fuel specified by 13 CCR 1961.2, and which are appropriate for the certification of large spark

- ignition engines.2 (B) (D) If the engine is not a gasoline

- fueled large spark

- ignition engine, then t he test fuel used shall be consistent with the fuel specifications as outlined in the "California Exhaust Emission Standards and Test Procedures for 2001 and Subsequent Model Passenger Cars, Light

- Duty Trucks, and Medium

- Duty Vehicles," as of January 1, 20 06 (last amended August 4, 2005) incorporated by reference in Section 1961(d), Title 13, CCR). The California fuel specifications are contained in the California Code of Regulations, Title 13, Chapter 5, Article 3, Sections 2290
