@buster brought to my attention this video patent is regarding Valvoline Blue Restore product that was developed several years back for Cummins engines that were suffering carbon build up & oil consumption. The guy in the video does claim to think this patent covers the Restore & Protect but who knows.
This video highlights some of the wording regarding Valvoline Blue Restore US patent papers.
- Trying to minimize oil consumption during use.
- Use of Aniline Point to describe solvency of the base oil
- A blend of two or more base oils to obtain solvency w/typical additives
- Aniline Point of particularly 60 degrees Celsius have been found to be effective solvency
- NOACK must be less than 15% and preferably less then 10% & generally less than 8%
- Preferably the VI will be greater than 120, preferably greater than 135, & more preferably 150 or higher
- Preferred polyalphaolefin & Alphaolefin (1-octene, 1-decene, 1-dodecene, 1-tetradecene)
- Possibly using Priolube 1973 (Oxidatively Stable Ester used in 4 stoke in 5%-30% ranges)
- Trying to strike the best balance between solvency & seal compatibility
- They make mention of a typical oil change interval of 5,000 mile w/a product like R&P.
- Possibly using group III, IV, V.
