Did You Know That?...

Viscosity can be intuitively defined as “Thickness of the oil film at a specific temperature”. Such a thickness is designated by the SAE GRADE, which could be 0, 5, 10, 15, 20, 25, 30, 40 , 50 , 60 (higher number = thicker). Thinner oils (low viscosity and lower SAE grade) perform better at low temperatures, due to the fact that oil thickens as temperature lowers. Thickers oils (high viscosity and higher SAE grade) perform better at high temperatures, due to the fact that oil becomes thinner at high temperatures. Most of today’s modern oils are multi-grade, meaning that they are able to adjust viscosity as temperature changes. Multi-grade oils are designated by a double number, the first one indicating Viscosity at cold temperatures and followed by a W ( for Winter), the second one indicating Viscosity at high temperatures. As car is driven, properties of the oil tend to deteriorate, due, to additives depletion, oil oxidation and thickening, and to the adverse impact of external agents, like dirt, dust, reduced efficiency of the oil filter etc. The rate at which contamination and additives depletion occur, depends on many different factors: the quality of the oil, driving habits, ignition, carburetion, the general mechanical conditions of the engine, crankcase ventilation, underhood temperatures, turbo charging and basic engine adjustments. Oil has to be changed before contaminations and deterioration has reached a point where engine damage or abnormal wear can result.

Why Synthetics?

Molecules in Synthetic oils are consistent in size and shape, so that they do not easily deplete, break down or oxidize at hot engine temperatures. No wax is present in Synthetic stocks, minimizing the risk of solidification at low temperatures. No contaminants are present eliminating the need of removal. This is way synthetic oils grant better and longer lasting properties in terms of protection, maintenance, consumption, lubrication and performance than any mineral oil. Synthetic Oils significantly reduce maintenance and fuel costs, better adjust to both very cold and very high temperatures and to “stop and go” driving, prolong the life of the engine, boost engine performance and impact more friendly on the environment. Agip was among the first to produce synthetic oils and, to the present day, Agip’s Fully Synthetic and Synthetic Fortified engine lubricants outperform the competition throughout the entire spectrum of performance.

Why Group II is Important

Agip is among the first and still few in North America to have converted to Group II Base Oils. Group II base oils (obtained through a process called “hydro-cracking”) are “ super-clear, almost entirely pure and free of contaminants. Their purity permits to formulate lubricants of superior quality, exceeding the most severe performance standards and significantly prolonging the average life of the engine. Agip Super Motor Oils, Agip All Guard as well as Hydraulic and Turbine Oils “X” series, are all formulated with Group II base oils and state of the art additives.
