I’m most interested in these TEOST results. I think I had some deposits in one of my TGDI engines, either from Mobil 1 Advanced Fuel Economy or the HPL P+; the latter of which does use those alleged deposit prone star VII. Of course the No VII oil doesn’t have those…do we know what kind of VII the other oils in this test video might use? I would like to know more about the influence of different VII types & moly additives on real world engine deposit results.
Even though the Ravenol/LiquiMoly used here don’t seem to have VW/MB approval, maybe the API formulations tested here still share attributes with their mainstay euro oils that do. They did the best on TEOST. Could this highlight some shortcomings of API sequences VH & IIIH deposit testing that still uses a port injected normally aspirated 3.6L pentastar engine? At least Amsoil appears to take deposit testing a little beyond the API minimum. API uses a 2.0L TGDI ecoboost for chain stretch and LSPI testing, they should be using an engine like that for all of the deposit and wear tests at API in my idiotic opinion.
