I opened up my OS .18 and my 2.5R.

My OS and 2.5R both have almost two gallons through them.

OS has excellent compression and the piston is spotless but I have never used ARO in them.

My 2.5R, however, was dirty and scratched inside and has horrible compression. It doesn't seem to have life anymore.

Whenever I pull the plug to insert the ARO, I presume dirt gets in and in turn gets stuck inside and rubs and grins the inside thus lowering compression.

Your thoughts?

I know this topic has been discussed before but I have substance and proof to back my theory.

If dirt gets into the engine throught the glow-plug hole then it is obviously going to ruin the engine, but the after run oil isn't really to blame. A quick blast of compressed air or carb cleaner (even WD40 will work) will remove the dirt from around the glow plug and allow you to remove it without getting anything in the engine. In a pinch even a very small flathead screwdriver can be used to remove dirt from around the plug.

Not to mention the fact that you should be pouring the ARO through the carb opening.

exacly, by carb, me evn changing glow plug i do this upside down to prevent dirt get inside, cause this part is very difficult to clean and easy to get dirt on it

You can hardly blame the ARO for your poor maintaince practices.
You've screwed up that engine, not the ARO. Just suck it up and learn from your mistake.

I'm crying.

You're being mean.

Booo hoo.

I don't want to play anymore.

I would just point out that every engine manufacturer out there (well at least most of them - haven't owned one from everybody) states in their manual to use ARO. That's enough for me to use it.
