No 87 won't hurt a stock engine. Infact it's designed for 87. Oh and this whole notion of the higher the octane the better yea that's BS. Unless you need the extra octane because of mods you don't need 91. It won't give you more power it's not cleaner etc. Trust me you learn these things when your dad works for Mobil.

i dont remember exactly how it works, but because the higher octane number gives you a lower knocking in your engine, the fuel is less powerful. therefore you have to put more in to get the same power, and only then it runs cleaner or something like that. therefore if an engine is designed for 87 and you put 91 in it, it runs with lower hp or something?????? i dunno.

There's a thread going about using Shell gas as opposed to other manufacturer's gas. Seems that people are getting really good milage and performance out of Shell gas.

I need to get rid of my engine and put a powerstroke diesel under the hood. I have to run 93 octane.........diesel is only 1.59 a gallon here
Since you mention it, diesel is only $1.55 here. Darn, I guess I am gonna have to go buy that powerstroke diesel now...

I have a diesel sitting in the driveway......so I kinda got it made. My boss at work kept trying to sell me his 2002 Passat with a diesel.......45 mpg and cheap gas......I'm kicking myself in the butt now
