I wouldn't touch the needles. That looks just fine.

If those little blips you are referring too are like quick, short "hiccups" in running it's possible that the engine is experiencing a little carbon ball fouling at the spark plug. The "blip" that happens is the plug mis-firing until the carbon ball at the gap is cleared. It's pretty common and if the oil ratios are reasonable there's not a lot you can do about it other than open the plug gap up more. That's not the best idea though.
