says lnSP but book doesn't indicate what that means any ideas

Your owners manual does not show the light and the meaning? There should be a diagram in the owners manual pointing out all the dash lights and their meaning.

No, the manual shows very little in regard to troubleshooting or codes

I downloaded a manual and there are quite a few pages showing all the warning lights and their meanings. Try looking for that. http://www.saturn.com/content/dam/saturn/northamerica/usa/nscweb site/en/Home/Owners/Owner_Resources/Manuals/en/us/2008/aura/ 2008-saturn-aura-owners-manual.pdf

I suspect you are seeing something to do with the Info system which tells you that there is a message on the DIC (Drivers Information Center), page 3-45.

Got it thanks. It sounds like when you need an oil change (which it shouldn't) it stops the car from starting. If that's true how do I get it to a service station
