Test Procedure to Evaluate Engine Oil Treatment Additives for Otto and Diesel Application Based on Sequence IIIF (ASTM D 6984) using a GM 151S Engine 2013-36-0145
The commercialization of additives for treating internal combustion engine oils in Brazil was regulated by ANP Ordinance n° 131, from 30.7.1999 and revoked by ANP Resolution n° 10, from 07.03.2007, where requires the performance proof of the referred additive following the ASTM Sequence IIIF bench engine test. The test PB/IMI-1109S3FGM151-2 establishes a procedure to evaluate internal combustion engine oils as well as additives against special performance conditions particularly operating at high temperature based on ASTM D 6984-09 Sequence IIIF procedure. This test measures oil thickening, sludge and varnish formation in engine components, piston deposits, oil consumption and camshaft wear.
The ASTM procedure also suggests the use of any engine that proves the competence to accelerate thermochemical deterioration of lubricants under severe operating conditions and temperature, allowing in that way the development of this test procedure.
This work is based on several tests and simulation to demonstrate the thermodynamic and combustion chamber geometry similarity between the Buick 3,8L 231CID serie II 1996/97 recommended for the Sequence IIIF and the GM 151S 2,5L engine used in this specific work. It also demonstrates the possible adjustment of test parameters to simulate the same critic operating conditions to evaluate oil and additive performance on a bench engine test under the same specific measurements. It allows the development and implementation of a local procedure according to recognized international standards, meeting the Brazilian legislation and the local Industry that does not have those facilities to meet the legal requirements.
