Ethanol in an LS??

Can I run 10% ethanol in my 1992 LS4? It is 90 octane and locally it's the same price as regular. I have heard both "yes" and "no" from people who know more than I.

TIA,
Macc

Yes, it is safe to use up to 10% ethanol for your 92 LS. You won't have any problems as long as you use the correct octane recommended in your owners manual.
