I have fallen on good fortune. Someone has made me a generous offer on a case of M1R. So it will be the next oil run through my new Toyota. After I have run M1R I will continue to test 5W40 oils. I am at slightly more then 5000 miles on this OCI. I might cut it short just to start geting a trend going. I am really woundering how Redline has held up with the sub zero temps, high rpm use, mega salt usage etc..... Eventualy I hope to see how a 0W30,5W40wt and 15W50 oil functions in this engine. This is a totaly modern engine design. Everyting in it is ultra light and ultra tight from what I have read about it in SAE papers on trade magizines online. I know that it uses micro grove bearings. These tests are not meant to test one oil against another rather the test is to find out if their is any corraltion between viscosity and wear in my engine. I also hope to find out if one brand is going to be significantly better then the other in the same viscositys. All oils HTHS will exceed 2.6 but will be less then 5.0. THe oils being tested are going to have diverse additive chemistrys and some will be G-III,IV, V or a blend of all of these! I will keep all abreast of my findings!
