Posted the second UOA for my wife’s 2006 Pontiac Vibe on bobistheoilguy.com for review.
Everything remained fairly constant between the two samples. The AMSOIL XL line of oils is a pretty stout product. We ended up pushing it out to 14,000-km/7-months which is a month overdue on time and 2,000-km under in mileage for the product service life.
