Love these turbos. Makes life so much easier. I had a oil drain tube get hit by road debris and cut it. I didn’t know until the engine started knocking so I steered clear of turbo set ups until these came along.
Haven't kept track on mine, but I'm still using the original grease cartridge I ordered with my turbo. I have the first gen water cooled oil-less in a low mount config, it's been on the car about 5-6 years now. At a minimum I grease at the beginning of spring every year when I take the car out of storage, but also did some greasings here and there after dyno session, before drag strip outings etc. My car is mostly a summer/weekend car. On their site it says each cartridge lasts 30 services so guess that would be 200+ plus pumps. I reckon even if you greased 2-3 times a year, the one cartridge should last the service life of the turbo or about 10 years. They recommend a 50k mile service inspection and rebuild if needed. All way better than any of my oil fed journal bearing turbos I've run in the past that's for sure.
