Seems to be a relatively new product. The new buzzwords in the additive industry are asphaltenes and IDID cleaning. Asphaltenes are why your fuel filter is black and the new standard for cleaning internal injector deposits is the Peugeot DW10 Injector Depositing Test which something different than the previous L-10 test. Some blenders are referencing this test in their advertising, some aren't. The cleaning ability of an additive, to me, is more important than lubricity and this product touts 3 times the detergency to clean injectors in this DW10 test. Schaeffer has a long history of formulating and a good reputation. http://www.schaefferoil.com/carbontreat_summer.html Anyone have an opinion on this? Not in additives in general, but an opinion on this product.
