That's what I've been hearing with both the 0w and 5w30 weights of edge that makes them quiet. A buddy of mine and I were just talking about it.
Interesting enough, when the wife's ecotec went from M1 to QSUD, it did not make as much noise either.....
not sure about the varnish part though. I think that might depend on the engine too..mine are all ecotecs, which are known to be easy on oil....
I would just go QSUD or Penzoil dexos here, but Edge really has me curious, since I have not used a castrol product in over 10 years....
If you decide to use it, I would be interested to hear the results. The only 0W-20 oils I can find locally are Edge w/ Titanium and M1 AFE. Normally I prefer Pennzoil Platinum but I can't find it in 0W-20.
Like you I've heard a bunch of stories about Castrol not being very clean and M1 being very noisy. Then again I hear stories of Pennzoil causing "waxy buildup" and I haven't had that experience so it's probably just rumors.
