hello looking for sho owners to dialog with near me. i was trying the eastern US but thats too far for any functions. i live in garrison Mt
just bought my first sho , an 89. somthing to recapture my lost youth in.
59 yrs young. hensho
anyone know what the actual compression ratio is of the early sho's.
my 89 seems to run fine on the middle grade gas with no apparent pinging.
i think the octane of this gas is less than 90. should i be using the highest octane available? octane additives? hensho
