Added one half quart to reach full capacity after check level alert.Low oil alerts typically only happen when you are critically low...perhaps as little as 1 quart (US) remaining. You actually don't need 4 quarts to safely run, but it ensures proper lubrication with some reserve. There is a minimal level where delivery of lubrication would be impaired due to the sump running dry. I'm not sure where that is, but 12% of total capacity shouldn't pose a threat.
Now, you're talking about 12% oil loss after essentially 4,000 miles (US). I'd be concerned as I normally notice no oil loss from amount drained and recovered compared to what I put in. Of course, I might not notice a 10% loss unless I marked the bottle to know what 4 quarts in was on the bottle before I put it in the motor.
How are you determining the loss? Measurement of oil drained against oil added?
Ah. Good to know.Added one half quart to reach full capacity after check level alert.
The low oil light should not come on until the oil is below the minimum level in the site glass but some wetheads the low oil warning comes on early if the oil is below the middle of the window.Added one half quart to reach full capacity after check level alert.
Reasonably sure.Oil level alert will come on only when the level is below the sight glass ring. How far, I’m not sure, but I’ve had it come on when I stopped and put the bike on the side stand with the engine running while I checked my phone. Of course, the actual oil level was fine.
It’s unusual for an LC to need a top up between services, but not unusual for some to be consumed. Half a quart (about 500 ml in proper language) in that distance is nothing to be concerned about in terms of internal combustion engine oil usage. Car manufacturers’ handbooks often quote a litre in 1000 km as not being ‘excessive’ (but it would be unusual!).
Are you sure you checked the oil under the correct conditions in both cases, and filled to the same point?
Thanks for the info.The low oil light should not come on until the oil is below the minimum level in the site glass but some wetheads the low oil warning comes on early if the oil is below the middle of the window.
We get the low oil warning on our 2016 bikes if the oil is below the center of the window.
Same for us. When I change the oil I make sure to get the oil level between the 3/4 and max level.With the oil level straight in the middle of the sight glass, I was getting the check warning every time I triggered the automatic check as per the instruction manual. Filling the oil up to 3/4 or 4/4 of the min-max scale got rid of the annoying false alarms and I no longer get the oil check warning in the dash.
