Valvoline Synpower Fuel Injector Cleaner?

[sciphi]

Browsing at Big Lots the other night, and stumbled across some Valvoline Synpower fuel injector cleaner, marked down a lot. The bottles looked old, but were not dusty. They were at a really good price, so I'm wondering if I should spend some hard-earned cash on them?

Today's a double-barrel question: They also had Greased Lightning fuel system cleaner for a dollar more per bottle. Claimed it was really really good. Could not find a list of ingredients. So, is this stuff worth it as well?

I seem to remember a couple of years ago when I first started on BITOG this was talked about very highly. Apparently no one remembers anymore.

Thanks! The Synpower cleaner was dirt cheap, so I may pick up a few bottles, like 4-5. Should go perfectly with my older car.

It this the red or gray bottle of Valvoline Synpower Fuel Injector Cleaner?

I've seen the gray bottles at Big Lots for $2.50.

Gray bottle.

Picked up 4 bottles. It likely can't hurt anything except my wallet.

Part #VV053, and the bottles are not quite gray anymore.
