I'm half way through second tank load and car feels much better. Connected my Pro-Diag and cylinder 4 knock at full bore has been reduced from 7.5 to 2.2.....now we's talkin!
Another 1/2 - 1.5 tank loads and I should be set.

You may consider running Chevron Techron concentrate ever now and then. Read up on it first....it's the real deal.

Peter, is that an additive or just Chevron gas?

Chevron gas has a lesser concentrate of the ingredient. Chevron not available where I live.

The stuff is great. Search the studies and compare.
My 1st tank of cleaner was Slick 50 brand....why? Because it was the most expensive! should work the best? nonsense!
Chevron Techron (go to the Chevron site) is cheaper and the way to go....been around since the 70/80's. I bought a 6pack over the internet....also found at AutoZone (funny, all other brands in plenty shelf stock....but, Techron?....only 1 bottle left. Tells you something)

After my stealership 5k oil change and tire rotate I'm good to go - not the free one from AoA. And actually a good experience with minimal effort. Mobil 0W-30 for the next 5k, free filter and free wipers and free rotation. Much better experience than my last fiasco.
