My '91 500 SEL has a a sump guard made from 1/2 inch boiler plate steel and my 300 CE has a guard doing the same job made from paper thin paper mache ! I am still not really sure what either is designed to do ?. . . . . . . .
what is does do however is that I need the top sider every time I need an oil change ( 3000 kms, oil and filter whether I need it or not ! .... )
