I think you have to keep some things in perspective regarding this test ....You started with a 6 qt sump and have since added 5 quarts of makeup oil. So I'm not surprised at all the Mobil 1 has lasted for 13,000+ miles. I think a petroleum oil like Schaeffers would easily last 10k+ miles under these conditions and I believe that Bob would agree?

In retrospect, it would have been better to sample every 3k miles with a suction device, so that you weren't adding so much fresh oil. Don't get me wrong, I think this is a very worthwhile and interesting test, but I probably would have configured it a bit differently to make it more demanding ....

sounds like a contributor to my test I proposed!

This is the only problem with the test as I see it. There were just too many samples drawn. I know it's hindsight now, but every 2-3k would have been better. Too much oil was taken out and replaced.

I do think Mobil 1 is capable of this length of drain, but I don't think this test is paints an accurate picture.

QD, yep, #3 is the thrust bearing... I agree, that's my prime suspect for the copper.

Guys, keep in mind the original purpose of the test was to compare different oils. So as long as we use the same test regimen across all oils, we will still see some success with the original intent.

I still think the top-up oil, up until changing the filter, was fairly reasonable.

Well, the same amount of oil should be used with all oils then other then the TRUE 1.5qts of make up oil. So 3MP has a point bc each sample is 4oz. What we can learn from this I'm still not sure of.

Once we get into the Amsoil test we'll have an idea of which holds up better.

Cheers, 3MP
