Decided to see what the pistons looked like on top via the spark plug hole using a flashlight.

It was pretty hard to tell, but I really only saw rust, or what looked like rust on the tops of the pistons. Also noticed a slight bit of white on the spark plug arches.

Car seems to run ok. I feel like it's lacking a little power but that might be normal.

27k miles. Only mods are intake, s pipe and catback.


What's going on here?

 

You sure its not carbon build up?

 

I don't know man. It looked like rust. I'm hoping this is normal or something. I did run 93 gas for 25k miles before learning I might be doing more harm than good. I now only use 87. No idea if that has anything to do with it.

Ran 1/2 bottle of BG 44k to clean up any deposits. (1/2 the can spilled out due to wrong funnel used- my bad). Maybe I should use another can.

 

i think your thinking too far into this.

 

impossible for there to be rust unless the car has sat for a very very long time. What youre seeing is carbon buildup left by unburnt fuel. the white on the arches is generally normal too, we have fairly hot plugs.

No. Reading too far into this stuff man.
