I don't know engine numbers so I am right by saying the 103 is the 3.0L and the 104 is the 4.2L

If the 3.0L is only 9.2:1 , then why do I have to put premium gas? Can I get away with 87 octane? This seems like low compression to have the hi octane??? The 4.2 I can see, but not the 3.0?? What do you think?

'89 420 SEL
'90 300 SEL

'84 300 SD (sold it)
