I understand the procedure, searched it and seen different outcomes.... and all that good stuff.
Now the PO said he used synthetic oil... for how long who the **** knows.... i currently run the car on regular castrol 10w-30.
Now since the PO ran the car on syn for 1 or more years, would the carbon build up be too great to cleanse with water treatment, causing large pieces to get caught and cause damage to the apex seals? Now i know it seems like ive answered my own question but would still like some input...

Thanks

There is nothing wrong with synthetic oil.

I have heard pro's and con's of using synthetic and the only good argument I see is that MOST synthetic oils have a higher "flash" point, meaning the oil itself burns at a higher temperature than conventional oil. This would mean supposedly more oil residue would be left over in the engine.

That being said, I think it was only some of the racing synthetics like royal purple who claim their synthetic doesn't suffer from the high flash-point and do burn up like conventional oil. There might be others but I haven't look into it much.

Regardless, carbon is very hard to remove. I would say don't worry too much about it and just make sure to REALLY drive the car once in a while. Run a water treatment, tune-up, and call it a day. If there is build-up already which is inevitable, there is not much you can do to clean it out besides running at WOT for long periods of time.

you should be ok, i dont think carbon deposit will break off in chunks in that sense.
