| Modern-day engine oils, there are two myths. "Other than running out of oil, the primary oil related problem that kills engines is DEPOSITS that cause stuck lifters, stuck piston rings and blocked oil passages. IT IS NOT WEAR. "Engine oil viscosity has VIRTUALLY NO EFFECT ON WEAR." Oil's ZDDP (zinc dialkyldithiophosphate) additive is very important in protecting heavily loaded, boundary-lubricated parts, such as cam lobes, valve lifters, piston rings and cylinder bores. Boundary lubrication results when metal-to-metal contact occurs, "which in turn causes the depositions of the antiwear film from ZDDP." While the antiwear properties of ZDDP will not completely eliminate wear "they will reduce wear by orders of magnitude so that it will not likely be a limiting factor on engine life." New formulation technology can use ZDDP much more effectively. However, the oil viscosity will not have any practical effect on wear. INDESTRUCTIBLE BEARINGS? The other major part of the engine that oil must lubricate and protect is journal bearings. Examples of journal bearings include the points where piston connecting rods join the crankshaft and where the crankshaft is supported in the engine block. If a journal bearing initially contains a film of oil, it is simply not possible to squeeze all the oil out by any loading of the bearing. If the bearing and journal are not damaged, the surfaces simply cannot be forced into contact. Undamaged journal bearings with debris-free oil flowing are virtually indestructible. Bearings get damaged and fail at a later point, even with the oil flowing, most often by oils that have to high a viscosity, and thus are not pumpable at the low temperatures that today's engines will start. That last sentence contains two key elements-- "today's engines" and "too high a viscosity". OIL PRESSURE: THE REAL STORY Oil pressure is the other major problem that is over looked. An oil PUMP is exactly that a pump not a compressor, the oil should flow thru the engine not be compressed thru the engine. The higher the oil pressure the greater the amount of pressure that is put on the internal parts of the engines, not necessarily lubricating. To lubricate properly you must have proper film thickness and flowablity, think of it like trying to push molasses thru a straw. The higher the oil pressure the more horsepower it takes to push that oil thru the system. Oil pressure is a direct result of resistance. resistance=friction=heat=lost horsepower. |
