even though I've been here a while, I never really got into the matrix of oil analysis, until now. School me if needed, but I have a question. A UOA on a differnt page showed a sus visc. at 210 to be at 44.8. According to the visc. charts, that shows the oil sheared down just a tad below a 20W, which would still be high for a 10W. Looking at the Cst visc. at 100 and it showed 5.65. That equates to about the same, below the 20W, but high on the 10W. My question, yes, it's not in spec with a 20W oil, but it still is a strong 10W weighted oil. After reading a lot of post on this, I was lead to believe that the oil is absolutely trashed and will kill your engine because it's out of range. However, it is still protecting the engine as a 10W oil. Notice, I used the word protecting. Does a 10W oil not protect an engine also? The only spec that it's out of is because it now doesn't identify with a 20W, but that should be expected especially since it's a turbo and getting the heck beat out of it. I'm willing to bet that Honda knew this and tested for this as well and they are OK with it. I've read numerous forum from civic and crv owners that complained about dilution, but that's all they've done. Complain. I've only read one post that the owner claimed the dilution eroded his cams and caused engine failure and Honda is now giving him a new engine. The more I research into this, the more I'm learning that this whole dilution thing isn't that bad as everyone is making it out to be. The sky is NOT falling.
