are the newer SD's smaller reserve?

sdls have 23 gal capacity, aprox. mine does. it is a 90 350sdl.

all this talk about italian tune ups....

when i get out on the highway i run about 80 here in 70 speed limited indiana. running at that speed for an hour or so will eleminate the need for any special efforts to "clean her out".

if you always are stuck around town then that is a different story.

all fuel guages are somewhat approximate even when operating correctly. my benz guages generally are a lot more accurate after 20 years than my gm guages were when 2 years old.
