WHY DOES OIL LEAK?
We have discussed above how contaminants like wear particles are generated and contribute to increasing formation of sludge and resinous matter. Sludge, being acidic, attacks and reduces life of oil seals. Sludge has an electrochemical attraction to metal surfaces and will deposit on oil coolers, reducing heat transfer efficiency. This hard scale is just the same persistent grime in ovens and pans (like blackening of pan or tawaas) This leads to increased operating temperature, reduced viscosity & consequently higher leakage. It is generally thought that oil leakage is independent of oil contamination. Our studies prove that leakage is mainly due to oil contamination, with sludge being the prime contributor.
