A real-life example of PM Lubricants' Identigraph Reporting Procedures as used with On-Site, Diagnostic, Electronic Oil Quality Monitoring
The Identigraph graphically represented below was used on:
Make/Model: CAT D6D (Diesel Inject) 3306
Lubricant: PM402+ Turbolife Plus
Compartment: Crankcase (Sump Capacity 30 litres)
The following comments relate to the above Engine Identigraph for a Cat D6D 3306:
- 122 hrs: 5% total contamination, engine running cooler and quieter.
- 194 hrs: 10% total contamination, running cooler and quieter. Top up less than 0.4 litres.
- 254 hrs: 15% total contamination. Oil Filter changed. Change in graph gradient indicates problem and need for lab test. Lab test indicates Sodium (ie. Coolant leakage). Machine operator advised of possible coolant leak.
- 322 hrs: 40% total contamination - Lubri-Sensor indicates possible fuel dilution. Seeing Radical gradient on graph alerts operator to find coolant leak. Cooling system seal changed - oil left untouched.
- 475 hrs: 95% total contamination. 1.5 litres of top-up. Increasing radical gradient on graph suggests additional problem. Lab reports high silicon (dust). Air filter is changed.
- 500 Hours: Oil Filter changed.
- 611 hrs: 60% total contamination. Top up Nil. Note that all contaminants are reducing through oil filter efficiency. Not necessary to change oil.
Note: After 611 hours, gradient angle has now returned to similar gradient as at 0-122 hrs, indicating normal rate of contamination.
Total oil top-up in 611hrs: 3.5 ltrs, including 2 ltrs for filters. Previously, pre-PM, operator would use 2 litres of top-up every 250 hours.
Without On-Site, Diagnostic, Electronic Oil Quality Monitoring of lubricant contamination, the operator would remain blissfully unaware of the problems until it was too late, which no doubt would have cost him money in repairs, down-time and lost business.
