My 1989 Volvo 740 used .25 qt every 3,000 at 286,000 miles. 3,000 mile conventional oil changes with a Mann W917 filter.
I purchased a 1991 Volvo 240 in November and drove it 1,080 miles from Texas to Connecticut. The engine burned 200 ml of oil in the first 3,000 miles. The two previous owners changed the oil every 3,000 miles with a conventional 10W30 and a Mann W917 filter.
This routine seems to work well with the Volvo 4 cylinder Redblock engine.
That said, I’m switching to HPL so I can extend the drain interval. I’m tired of changing the oil so frequently. I hope this new regime works as well.
