While driving fast the other day for 20 minutes or so, I heard a very high requency whine that I could only attribute to the turbo. Can someone tell me what is going on?
I switche to Castol full sythetic 5-50 weight 2k miles ago, and wondering if that could be too light or a cause of this. I traded e-mails w/ a tech. at Castrol before switching, didn't think it would be hard on turbo, only causioned about oil leaks as engine scrubbed w/ sythetic.
Normal tooling around town doesn't seem to cause the whine, it's only happened once.
Car has 164k miles, 90 9000 CD
