I disagree to a point.
I have had bran new engines that had Cross Hatch in them some looked better than others while still some had non at all. I think it depends on what mood they are in at the factory at the time lol.
My very first China came from a dealer who is no more but it was a bushed motor that thing ran better than anybody's motor did around me! It had very visible cross hatch in the cylinder when it was new and ran a very long time. I had not used the said Opti on it but I have seen Opti first hand on friends motors and I have no Qualms about it. None of us have ran it at 100/1 tho about 50/1 or 60/1. That I know of. I have a huge case of another oil to finish off.
I have implemented a cocktail tho of a hint of opti with my oil I need to use up tho.I wanted to to get those friction modifiers implemented. That one is at 50 to one. 10 of is opti and all has been good.
I know these guy's here posting quit well if they say it works. It works just like they say it does! I have been becoming quit fascinated with this friction modifier agent in Opti!
