ASTM-D-6335-98 STANDARD TEST METHOD FOR DETERMINATION OF HIGH TEMPERATURE DEPOSITS BY THERMO-OXIDATION ENGINE OIL SIMULATION TEST
This test method covers the procedure to determine the amount of deposits formed by automotive engine oils utilizing the thermo-oxidation engine oil simulation test (TEOST). An inter-laboratory study has determined it to be applicable over the range from 10 to 65 mg total deposits.
A sample of the engine oil at a temperature of 100°C that contains ferric napthenate and is in contact with nitrous oxide and moist air is pumped at a set flow rate past a tared depositor rod. The rod is resistively heated through twelve, 9.5 minute temperature cycles that go from 200 to 480°C. When the twelve cycle program is complete, the depositor rod rinsed of oil residue and dried and the gross rod mass obtained. The sample is flushed from the system and filtered through a tared filter. The mass of deposits on the rod plus the mass of deposits on the filter is the total deposit mass.
The test method is designed to predict the high temperature deposit forming tendencies of an engine oil. This test method can be used to screen oil samples or as a quality assurance tool.
As a consequence of a close collaboration between Chrysler Corporation and Savant Laboratory, a small bench-top instrument was developed to simulate engine operating stresses on the engine oil. The area of particular interest was deposit formation. The ability to change a variety of test parameters on the TEOST apparatus lends itself to research work beyond the original Protocol 33C procedure.
Since its introduction, the TEOST Protocol 33C has been incorporated in the ILSAC GF-2 specification. This test, along with a new protocol yet to be named, is expected to also be included into the GF-3 requirement.

ProTecta Engine Treatment aids motor oil in its lubrication function as some oil must reach the area of the top piston ring in order to lubricate the rings and the cylinder walls. This oil is then exposed to the heat and flame of burning fuel, and part of it actually burns off. ProTecta's synthetic base burns cleanly under these conditions, leaving almost no carbon residue. The detergent/dispersant additives in ProTecta work with motor oil to keep the piston rings free in their grooves, thereby maintaining compression and minimizing the amount of oil reaching the combustion chamber. This not only reduces oil consumption but more importantly, keeps combustion chamber deposits at a minimal amount. ProTecta unlike other engine treatments, not only treats the metal but is fully fortified with additives to treat the oil as well. Almost every new engine oil category improvement calls for additional additives to work under engine manufacturers guidelines. This is especially true in engines equipped with turbochargers as they require a steady flow of oil to the center of the turbo bearings to provide necessary lubrication and cooling.
According to the API "Since stop-and-go driving most often does not permit the engine to reach efficient temperatures, it is actually among the most severe types of car operation. Under these conditions the rate of oil contamination is high, and the ability of the oil to overcome the effects of the contamination is low. Low-temperature driving, short runs, and light-load operation all promote water accumulation, fuel dilution, and the formation of sludge, varnish, and corrosive acids". This is why ProTecta us formulated with additives to prevent this accumulation of deposits.
The types of service we drive under and the climatic conditions that we operate our engines under vary greatly. When traveling at moderate speeds on short trips or driving in traffic under stop and go conditions, we use only a fraction of the engines power. Because the cooling systems must cool under a variety of conditions, they can overcool the engine during those short trips we take. In such light duty service engines and motor oils warm up slowly and do not often reach proper operating temperatures. Under these conditions incomplete combustion will occur, as soot and partially oxidized hydrocarbons undergo further oxidation in the crankcase, which forms sludge and varnish deposits. ProTecta with its detergent and dispersants offer extra protection in such driving conditions.
