Bob Teague’s AMSOIL Offshore Racing Team recently saw firsthand how well AMSOIL products are protecting their engines. During the 2009 season, the team clocked over 3000 miles of racing and testing, using only AMSOIL Dominator Synthetic 15W-50 Racing Oil. In preparation for the 2010 season, the team sent their Mercury 525 EFI V-8 engines off to the Mercury Racing to be torn down and refurbished. Mercury technicians found that wear was “minimal to non-existent and that the engines were extremely clean internally”. They had never seen a set of racing engines in such good condition after full year of racing. Check out the photos and testimonial at Mercury 525 EFI Powerboat Racing Engine Teardown. Over the years we have found that experiences like this are the norm rather than the exception.
