Highway oil consumption (11 Viewers)

1997 80-series @ 368,573 miles

Driving Vancouver, BC to Edmonton, AB. Did first half yesterday, lots of uphill and heavy driving on passing lanes. Oil reads low (L on dipstick) after letting engine cool off for 10+ minutes. I've got 1 litre with me to add.

Is this normal?

Going to stop in at next Lordco to get more oil.

So that's about 700 miles, and your oil was definitely at the full line when you started? These beasts do have a tendency to burn oil, and yours is high miles.
However, 1 quart in that distance does seem a bit excessive. You can direct the service station attendant to "check the gas and fill the oil please".

If you don’t know the exact level when you started than it’s hard to determine if you have an issue. I would get it topped up and monitor after 500 miles. Many have posted around a quart of usage every 1000-1500 miles on higher mileage motors.

How fast were you trying to go? It matters. These things burn oil the faster you try to push it; the sweet spot seems to be about 60mph. Any faster than that, and I'd expect higher oil consumption, and I'm on a fresh short-block rebuild with 25k miles, rebuilt head and fresh spark plug seals.

(*Please reply in mph vs. kph - as I don't speak metric system.)

If the original HG and associated seals etc then sounds normal, also what grade / type oil do you use?
mine did similar prior to the HG going and after re doing it uses nothing, just a leak at the oil pump housing which i keep putting off doing.....
