Why is Storage Seal Rust Inhibitor not recommended in the newer EFI and OptiMax engines?
Storage Seal Rust Inhibitor uses a thick base designed to protect the internal engine surfaces. In some applications we have seen a build up of the thick base inside the injectors, causing the injectors to stick or operate incorrectly. On these models we recommend Quickleen and 2-cycle engine oil as a replacement for Storage Seal Rust Inhibitor. Quickleen is used to clean the injectors. The engine oil lubricates, as well as prevents rust from forming. We continue to recommend Fuel System Treatment and Stabilizer to help prevent the formation of varnish and/or gum in the gasoline. Always follow the storage procedures outlined in your Operation, Maintenance & Warranty Manual or Service Manual.
