I just checked out Lube Control's redesigned website. under independent tests you can read Southwest Research Institute's test on FP-plus. It sounds really good but I'm confused by what it says about the HFRR test. Did it lower the tested fuel result by .37 mm or to .37mm (if that is the case, what was the starting HFRR score?)
