If you're buying lube service and you deliberately choose the slowest option because you personally don't like super fast cubes then you're out of luck because hidden behind a link it provides details on the service where the slowest option does not include core lubrication. This means that you are left with extremely loud and annoying grinding noises coming from the springs.
I think this is super misleading as lube service should cover all areas that need it. Lube type and lube service should be separate options so no matter what speed you want you can still get the same service. I'm forced to buy extra lube just to fix this issue.
