For petrol gensets
XLD 20W-50 API SG
As you used XLD 20W-50, we are assuming you have a petrol genset. Valvoline XLD 20W-50 is made using second generation Group 2 base oils. It is the only API SG rated product made using Group 2 base oils in Pakistan. All other API SG grade oils in Pakistan all use obsolete Group 1 base oils.
Group 2 base oil lubricants can operate at a higher temperature than Group 1 base oils, which means under equal conditions the oil loss is less in Group 2 base oil lubricants. Group 2 base oil lubricants are also clearer in colour and have a higher viscosity index as compared to Group 1. Group 2 also gives longer drain intervals, cleaner, quieter and smoother engine operation.
What is the size and age of the genset ? There is always a little oil loss during operation, which varies very much according to the age and state of the generator as well as the running conditions and environment it is being used in.
You are welcome to call our office on +92-21-35122796-7 or +92-335-2176661-2 and one of our technical team would be happy to discuss the issue with you.
