Will using an oil bypass system void my vehicle’s warranty?

A properly installed AMSOIL Bypass System will not void your vehicle’s warranty. According to the Magnuson-Moss Warranty Act, to affect vehicle warranty an aftermarket part must be directly responsible for the failure.

WHAT AMSOIL WILL DO TO CORRECT A DEFECT COVERED BY OUR WARRANTY:

  1. The Bypass System and filter(s) must be returned.
  2. If there is engine damage and the vehicle is under warranty, file a claim with the original equipment manufacturer (OEM) and notify AMSOIL at (715) 399-8324 immediately. In the alternative, you may mail a claim notice, along with the OEM denial, to AMSOIL INC., ATTN:Technical Services, 1 AMSOIL Center, Superior, WI 54880, postmarked within 30 days of failure or alleged defect.
  3. Keep the filter(s) and failed parts for inspection by AMSOIL unless given to the OEM. You must allow the AMSOIL Technical Services Department to examine the Bypass System and filters and, if necessary, the engine or equipment to determine the extent of damage and whether it was caused by a defective Bypass System.

How long can oil drains be extended when using oil bypass filtration systems?

AMSOIL Ea Bypass Filters are designed to remove fine particles; they are not meant to extend oil change intervals beyond original recommendations. However, when fine particles are filtered out of the motor oil, it may be possible to attain longer drain intervals. This should be determined by used oil analysis. In addition, the use of an AMSOIL Bypass System may allow for the use of larger oil filters, which can increase filtering capacity.
