SEMI-synthetic oil is generally part synthetic, part petro-oil. You can silence those lifters by running a REAL synthetic oil. Your choice. Note: I'm not saying Valvoline 20-50 is bad oil. It's good oil. But Glen's post is more evidence that it's not AS good as synthetic; not even as good as semi-synthetic. Al Powell Voice: 409/845-2807 107 Reed McDonald Bldg.
