Depends on the amount of coolant necessary to top it off. I am running Purple Ice in two of my 748s, myself. It mixes to a ratio of 1oz per quart of 50/50 mixture, or 2oz. per quart of pure water. I suppose it is okay to go a little over that, since my manuals recommend 60/40 (water/coolant). I wouldn't go running a full bottle in there, though (but I am a stickler for mix ratios, and things like that). If you are down more than a few fl. oz., I would add the proper ratio of Ice to the mixture, then top it off (to the "max" line) with deionized water, when you can get around to buying a jug.
The Ice will add lubricity, and the extra water will assist in cooling. Just be sure to get that ratio as close to OEM recomendations as possible if you live in a colder climate area. More water means better cooling, but also decreases the anti-freeze properties. Ice will add the needed lubricity for those seals and water pump.
The stuff seems to work marginally, however, I suppose it is more a placebo, than anything. It still runs hot because......... well, it's a Ducati. 😉
