Has anyone heard of Zyntek Engine Protectant? It is labeled API SH/SJ/CF/CG. Zyntek exceeds the following specifications: · API SH, SJ, CF · ILSAC GF-1, GF-2 · ACEA A-1, A-2, B-1, B-2 · Chrysler MS-6395H · Ford ESE M2C-153G · GM 4718M · 6094M · US MIL L-46167B · VW 505.00, 501.00 · Mercedes Benz AG 226.1 · JASO VTW Spec. They recommend 8-10k mile OCI with filter change every 4-5k miles. It's $99.99 for 1 case (5 liters) & oil analysis. It comes in 3 flavors: 5W30, 0W30, & 20W50. "Each engineered so the molecules are consistent in size and shape. Zyntek’s molecular consistency promotes very quick flow of oil to critical engine components during start-up, idle and heavy load regardless of your engine’s temperature. Zyntek’s pure synthetic formulae are free from the contaminants, sulfur and asphaltic residue that cannot be completely removed from common crude petroleum oils. Our short-run and endurance testing on the Autobahn in Germany and the grueling 1 Lap of America has proven Zyntek to be ‘perfect’ for superior performance and protection." I assume it's German. I found it on Zymol's website while looking at the wax.
