Oil Filter Changed How Often? Mobil1 experiment

[FetchFar]

Does anybody know how often they changed the oil filters on the Mobil1 Land Rover oil experiment, driving around the world? Pictures of the valve covers off in the link below.

Maybe some remember the Mobil1 synthetic oil test in around-the-world driving in a Land Rover where they didn't change the oil until (not completely anyway, see http://longitudediscovery.com/TheGreatMobilHoax/index.htm ) the vehicles completed the trip, some of the vehicles anyway.... It does show the sand/grit/dirt building up. I can't tell if they changed the oil filters.

I found this statement: "Baggarly explained, "Drive Around the World's LONGITUDE Expedition is conducting a motor oil endurance test for Mobil 1, 0W-40 with SuperSyn(tm). Our agreement with Mobil 1 is to run the entire 32,000-mile global expedition with no oil or oil filter changes in all four LONGITUDE Expedition Certified Discoverys."

I find it hard to believe they wouldn't change out the oil filter. The marketing thing they were going for was to claim the oil made it to 32,000 miles, so why not change the oil filter every 10,000 miles or so?

My 1994 LS400 with 360+k miles had FCI (Filter Change Interval) of 1 year, OCI is 6 months with dino and 12 months with synthetic. The filter was never better than mid-range such as P1, Bosch Premium, Motorcraft. It even had low end filters such as Fram Extra Guard, Pep Boys' Pro-Guard ...

The engine is still running great.

If those truck's engines are clean, M1 oil and M1 filter can handle it without a need to change filter every 10k.

They weren't that clean. They discuss how, in going around the world, they encountered a lot of third world countries with dirt roads, had to seriously change out their air filters, and we know air filters still allow dust below 200 microns to enter the combustion chamber. That would leave the oil filter with a lot to clean up, yet, on 2 of the 4 vehicles, it appears they had the same oil filter on for 32,000 miles of severe dusty service.

Wow, it may be that Mobil XOM will not ever talk about this "hoax" with the Land Rover expedition project again for legal purposes. I mean one qoute from the journal was "The oil samples came out like soft-serve chocolate ice cream. "
http://longitudediscovery.com/TheGreatMobilHoax/index.htm
AND the fact that the expedition's website is now calling their former sponsors experiment a "hoax", a bad divorce I guess.
The Drive Around the World Longitude Expedition was more like a I-hope-we-make-it-with-chocolate-pudding-in-our-engine trip.

From everything I have ever seen with companies who sell extended oil change oils, i.e., Amsoil and Mobil 1. I have come to the conclusion that there is no such thing as an extended life oil. All oils break down over time, cause sludge and varnish if not drained at appropriate intervals and do not last as long as stated under anything but optimum conditions. I will never run an oil for an extended period of time and by extended, I mean over 10k miles. Not 3k miles or anything ignorant like that. That being said 10k seems to be the max IMHO that I would run any oil and that would have to be in optimal conditions, like 70 degrees, clean air, and mostly highway driving.

Its true that Mobil1 XOM did a taxi fleet test where they had 15,000 mile Vegas taxi oil change intervals, and tore the engine down at 116,000 miles, and everything looked great inside, clean.

The Land Rover experiment never changed the oil filter in 2 out of 4 vehicles used (2 vehicles "accidentally" changed oil and filter during the run). Maybe a simple oil filter change would have helped the gunked-up engine get the particles out, as it appears they were running in oil filter bypass after a while with that level of sludge.

Mobil XOM does mention the embarassing Land Rover experiment on the Indian website, not on the North American website:

They were CPO'd vehicles. Who knows how much crud was already in the engines. Weird for Mobil to suggest such an extended interval under these conditions.
