Maybe I put too much Redline SI-1... I poured the whole bottle 15 Oz with full fuel tank, since the shop that sells it advised me to do so...
Will drive as much as I can and top up the gas more often to see if that makes any difference..

Always check compression/leakdown yourself and don't take what someone else does as gospel.
You should be doing compression and leakdown every couple years or after 30,000km let's say, it's a indication on whats going on with your motor (using the same gauges would be ideal, so you can see differences).
Check the valve lash and see if they need adjustment.
Redline stuff is good! just be careful on how much you use and do the calculations, caution on the less side, too much is not a good thing either.
Let us know the compression/leakdown and valve lash numbers

1 Bottle for rapid clean up. 1/3 oz to 1/6 oz per gallon on subsequent fill ups.
I like to go slow when it comes to adding chemicals to my car.
So 1 bottle = 15 oz. Therefore, 1 bottle is meant for 45 gallons. S2000 takes 13.2 I believe.
I understand they want to concentrate it on the first shot. But I'm just trying to put it in perspective.

Agree for that. Adding too much fuel cleaner could cause engine misfire I believe. I'll see how it goes after several hundred KMs driving.

Today I did a compression test and turned out to be cylinder 1 only had 110 psi while all other cylinders had 220+ psi. Obviously something wrong with cylinder 1.
Since I don't have the tool to do a leak down test so I may stop from here. What is the best / worst case? Can a cracked retainer cause this? Will a valve adjustment help? I know I am guessing too much but a leak down test will tell.
Any one can recommend a shop in west of GTA I will be much appreciated!

Cyl 1 sees more heat on the exhaust valves.

Check the valves cold
Check compression hot
How does the car drive all things aside?

110 to 220 is a huge delta though. Could be a combo of valve seat possibly some scoring.
