Service bulletin M1510

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

SERVICE BULLETIN M1510: MILWAUKEE-EIGHT ENGINE - NEW OIL FILTER. PURPOSE: To inform dealers of an improved oil filter for the MKE-8 (Milwaukee-Eight®) engine. The new oil filter uses the same synthetic 5-micron media as the current filter, however, the new oil filter effective media surface area was increased by 25%. The increased media supports the higher oil flow rate of MKE-8 engines. See Figure 1. Fitment, clearance and performance testing has only been performed on MKE-8 vehicles. All Twin Cam vehicles continue to use the current oil filter.
