some test data on M1
If you really care about the topic, you'll research it for yourself. There will always be M1 nutswingers, but I'm not one of them, too many personal negative experiences and test data to go along with...
thin at temperature (increases risk of shear)
personal experience with 2 cars that sheared, both had Redline put in afterwards and were fine.
extremely low oil pressure at idle.
dozens of rod bearing failures (search it on NASIOC.com)
Just a general bad mojo for me..I like Redline.
Please feel...
