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.
When my Mk6 was at 100k+ and burning up oil every 2500-3k miles, I got a tip from an old audi master tech to use BG MOA additive with every oil change. Cleared up the consumption and let me get up to healthy 5k changes with plenty of oil left. Drove it to 185k still running like a top.
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.
BG FrigiFresh and a new filter
Put two cans of BG 44k in a 32 gallon tank of gas and after running it through the truck now runs pretty hard right up to it's speed limiter. I've become a firm believer.
BGs Syn Gear Oil and Super Dot4 were both pretty solid offerings besides the 44k. Their high pressure grease also worked well for GM slip yoke clunks.
I know BG products actually do something. I had a buddy with an 04 WRX with 240k miles. He put 44k in every other fill up. When the engine finally blew, we tore it apart and the valves were clean as a whistle, looked brand new.
Although our shop use(s) BG products, the latest recall on 2005-2007 Odyssey master cylinders is due to the usage of BG DOT4 brake fluid (10-069) deteriorating the master cylinder main seal.
