Oil temperature 17 degrees cooler

Two near identical trips on consecutive days show cooling fans keep engine oil temperature down.

Day 1: Parramatta to Sydney city along Victoria Rd. Start 7am, ambient temp approx 18°. Heavy traffic and slow speeds.Fans turned on 10 minutes into the trip. Maximum oil temperature – 100°

Day 2: Parramatta to Sydney city along Victoria Rd. Start 7am, ambient temp approx 18°. Heavy traffic and slow speeds. Fans not turned on at all. Maximum oil temperature – 117°

17° difference – does it matter? The motor company says oil temperature should reach about 110°, so 117° is on the high side. See cooler engine oil for some info about oil temperatures.

These two trips demonstrate these cooling fans have a definite and beneficial impact on engine temperature, especially in heavy traffic condistions.

I’ll run this test again once the weather warms up more.
