IMHO...it is so touchy to get it right ......with filter change .....I just go with 5 qts. and wait until I have actually ridden it a trip or two ....then go for an accurate measure..................If you put in 5 qts. there is no way there is it's too little and can possibly hurt / damage the engine.......I once had a GF who asked me to check her OIL in her car ( 7 qt. capacity )......it was 3 qts. low, now I know she had not put any oil in for at least a year, but it was still running......So I'm sure the Spyder can handle a few ounces low ..............Low is better than over-filling it .............Mike
Manuals always give you the capasity but how you drain and fill can vary the amounts. I drain the oil heated. I remove all plugs and filters. I refill one quart lower than capasity. Start engine and run/ryde till fan comes on then recheck and top off. It's never the same amount...always check the level, don't go by the capasity..
