Its seems for the bigger picture, protecting the environment is more crucial.. low sludge oil are a main challenge and now they are working on GF-5 standard.. <a href="http://www.gf-5.com/the_story/performance/" target="_blank">more</a>.. which specifically focus in low sludge so drain interval can be extended and of course, to improve fuel efficiency, piston cleanliness and cleaner emission.Now, who say sludge is not cause by oil? read on..Oil sludgeFrom Wikipedia, the free encyclopediaOil sludge or black sludge is a solid or gel in motor oil caused by the oil gelling or solidifying, usually at temperatures lower than 100 degrees Celsius. Sludge can be a major contributor to Internal combustion engine problems, and can require the engine to be replaced, if the damage is severe. Sludge is usually caused by the presence of water in the oil, and can accumulate with use. Ways to minimize sludge production and accumulation includes performing frequent oil changes, using synthetic oil and following the manufacturer's engine maintenance routine.Source: <a href="http://en.wikipedia.org/wiki/Oil_sludge" target="_blank">http://en.wikipedia.org/wiki/Oil_sludge</a>So, sludge is cause by water.. !! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite9" alt=":eek:" title="Eek!    :eek:" loading="lazy" data-shortname=":eek:" /> is anxious reading this?!  <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite7" alt=":p" title="Stick Out Tongue    :p" loading="lazy" data-shortname=":p" /></blockquote>
