What do you think of these compression test results

I have just done a compression test on the engine... (PSI)

1)191

2)185

3)188

4)191

5)190

6)162

Thats 15% difference between cylinder 1

I tested the 6th cylinder with some oil in it and i got 228psi. Tested number 1 cylinder with the same and i got 250psi. Which now equals an 8% difference.

But what does this mean? Because i understand that if the pressure goes up, its the piston ring as the oil in it seals the piston ring, but would that not mean that it should produce a similar reading to cylinder 1? EDIT: Or is this simply possibly caused by a marginal amount of more oil in no.1

The reason why i did this is to diagnose a misfire issue. Is this enough of a drop in compression to cause this?

It is slightly low in comparison, the oil will just show if its down to rings/bore, or valves, it pays to try all cylinders with and without, if you can get a leak-down test done it will be more conclusive, and no that small difference will not cause a misfire.

There dont seem to be alot wrong with those readings.I would'nt pay too much attention to % difference as long as all the readings are healthy which they seem to be.

Looks OK but as tricky said.

Thanks for the replies
