AoA All,
I went to the Liqui Moly outlet at I-8 Markaz, Islamabad & i met with an expert Mr Muhammad Anwar (0322 6001841). An expert, & he advised me to use 5W-30 oil for my fielder (it had done 46000 km on its odo meter). First he used "Engine Flush Plus" in the old oil for 10 minutes, then flushed the oil. Added some new 5W-30 Liqui Moly and then added "CERATEC" with more engine oil till the engine oil dip stick showed almost full.
WOW.....the engine sound ...was no more ..only wheels running on the road.....it was all smooth.....
He had asked me to get the filter changed (Guard filter after 7-8000 km), but change the engine oil after 10,000 km minimum or after 1 year which ever is first. The ceratec time is 50,000 km.........
