I have used an engine flush by bg products before on my 07 si to try to get it to clean up inside. I had no sludge in my motor but i was mostly trying to clean it up since my dipstick kept showing dark oil even after fresh oil changes and It really seemed to help since then.

BG makes a great flush product.
The BG engine oil flush is one of the best on the market but it's pricey.
100ekm-ként érdemes a gyűrűket egy adalékkal tisztítani (BG EPR a titkos megoldás) és megszűnik a probléma.
I have used BG ERP on my own high milage car since it had an issue with burning oil. Originally it was burning about 1 quart every 1k miles. After the first flush it improved a little. After the second flush it is burning 1 quart every 1600 miles (60% improvement).
I use the Liquimoly engine flush at my shop. I use it on my own stuff. It's not too harsh at all so it won't cause any leaks or loosen the big stuff and cause damage. Have used the heavy duty BG stuff on some Audi 2.0t with the oil consumption and it reduced the oil consumption significantly.
