Even the same relationship to the part number (first couple of digits indicates the reseller, the rest of the P/N is the application). Note however that NAPA "Silver" filters are NOT made by Wix. I don't know who makes them. Wix filters are good > quality filter at a price comparable to Fram's cheapest filters ( the PH > line).

They have a line of industrial filters that are well-documented and seem to come from a different planet (or at least a different manufacturing plant on the same planet) than their consumer grade products. The thing I like about Wix is that their product line is more seamless- the consumer-grade products are documented just like the industrial products. Of course that could all change next year. Federal-Mogul, for example, used to be a name you could trust on face value in parts. Now they sell a whole lot of made-in-China junk. You can't trust entirely in past performance anymore, unfortunately.

I did a test with "Dan Gurney's All-American" synthetic oil, in the mid-1970s, at Riverside raceway, a 95-degree day, and an S-W electric oil temperature gauge. Ran one half-hour practice session (full GP course with the mile-and-a-tenth straightaway) early in the morning, noted the oil temperature on the last 'hot' lap. Drained out the Castrol (GTX 20-50 IIRC), replaced the filter with new-same, and refilled with the Gurney synthetic. Ran the next session, just before noon, day had heated up a few degrees, noted the oil temperature on the last hot lap was 10 degrees cooler than at the end of the first session. Lap times were improved, but not more than what I'd learned to expect as a result of practice and tire-pressure trimming - which may have been in the wrong direction and cancelled or masked any improvement due to the oil, but I didn't think so. That's it. Close as I can get to "science". I have no idea if the synthetic of those days would be "full" or blend, or what it might have been in any respect other than it had Gurney's name on it and cost nearly ten dollars a quart. -- Frank ess

You are almost certainly referring to http://neptune.spacebears.com/cars/stories/oil-life.html. They went longer than 10,000 miles, but it looks like the "study" has been static since 2005. Ed

One of their better efforts at actually testing products instead of relying on self-selecting surveys and subjective opinions. They used the cars of a NYC taxi company and after substantial miles tore down and miked the engine internals. As I recall they found no significant differences between oils, and I think one was a synthetic. But I can't remember exactly. It was still a flawed test, since some of the limited number of taxis they used broke down and didn't finish the test, and they had no way to control drivers. Don't believe they even mentioned the latter fact. Wouldn't fit their "scientific" pretense. But at least they tried. --Vic

The test you are talking about was done in 1996. A copy of the article is available at http://home.mindspring.com/~ed_white/id11.html. Ed |
