:agree: That's definitely the way to go!
The 998cc V-Twins (or 990/991 series Rotax V-Twins) are relatively high revving high performance motors, and as such, they tend to use a bit of oil between scheduled oil changes. For most 'road riders' that could be anywhere from 'just a smidge' thru to something over 250 mls every 1,000 kms (sorry, too tired to convert for those still in the dark ages!

) depending upon how hard they've been worked. And if you ever do some serious track work &/or work them pretty hard for an extended period (ie. like riding saaay, 1600 kms in under 12 hours

) then you could even use something like 600 mls in that time/over that distance, &/or if it's a really hot day, you might possibly even use as much as 1 litre over that distance/day - altho that's not at all usual, it's still the nature of the engine to use
some oil between scheduled services, and more than usual if you work it harder/run it hotter than usual! :thumbup:
So if you're planning on doing a long trip, a track day, or otherwise working it harder than usual, it might be worth your while to try to fill it closer to the FULL mark on the dipstick than usual - but you still don't want to go over that mark by much at all! :lecturef_smilie:
And Tony, even if your oil is at its 'normal' operating temp when you check it, while adding a quart of (ambient temp) oil
may have brought it up to the FULL mark at the time of adding ONCE, it could well be different when you check & need to add oil later, saaay, after a shorter ride, or on a colder day, or working it harder for a while! So while that 'One Quart' of oil might be close enough for most 'working purposes', the volume of oil required to bring it from the ADD mark to the FULL mark may vary enough to be of concern
EVERY TIME you add oil! And that's one of the reasons you should always only add "
a few ounces" at a time, and "
Not a whole Quart", no matter
how convinced you may be that you can
always repeat your oil checking process
exactly as the manual describes.... Besides, can you
really match it
exactly, right down to the temperature of the oil (both in the engine & that you're adding!) and to the number of seconds that you're leaving your Spyder standing before checking the oil?? :dontknow: As soon as the engine stops turning over, the scavenge pumps stop and there will be some oil draining from the engine back into the reservoir,
AND there'll be some oil draining from the reservoir into the scavange pool at the bottom of the engine & maybe even elsewhere! :sour: Don't believe that the time of checking after shut down can be important?? Just check your engine oil level in the reservoir when you shut the engine down as per the approved process, then check the level in the reservoir again every hour after for the next 24 hours & see if there's any further changes in oil level.... then leave it & come back a week later & check it again!
