Perfect test conditions. Sorry, while I like Mobil products a lot, I'm not impressed.
These tests prove nothing...and lots of brands and OEMs are guilty of the same feel good [censored]. Want to see how it holds up...give to a old lady and let her short trip it to church and bingo once a week. Let it not see highway travel but once a blue moon.
I've put a lot of miles on various Camry models, I'd like to find out what repairs the test car(s) needed.
Lame. Car was probably on a dyno for year with the same, constant load on the engine. Main bearings shouldn't show wear as they're always separated from the journals with a film of pressurized oil.
This silly test doesn't take into account the rest of the stuff that wears out like suspension, tires, brakes, transmission etc. I bet that transmission wasnt constantly shifting and subjected to varying loads. That engine was probably only started 50 times if they only shut it off to changed the oil.
That test only proves that highway driving causes less wear than city driving which has been well known for decades.

Exactly, still people will buy into the hype. Too bad, Mobil is one of the only oil companies I have respect for with regard to their marketing. Let me drive the car for 30 years [10 years less than their test] and change the oil every 10K miles. Then they can tear the engine down. I'd be willing to bet, if it even makes the 30 years, they won't be posting pictures of the engine internals. LOL

What good is having a motor last 500k miles, when the rest of the car rusts apart, or falls apart by 300k ?.,,
The Kendall "Taxi tested tough" is a much better measure of a good oil. 10k oil changes on semi synthetic, real world conditions.

Not if you live out here and away from the beach. Even in our snow and ice country, we only use cinders and sand, no salt

As I said when we discussed the million-mile BMW E30, assuming it was on a rolling road at 65mph for a year isn't accurate. In the case of the BMW test in the 1980s, the million miles in 4years theory doesn't add up right assuming all-highway running.

However, if you put the math together (failing to take into account the 50K durability test done in the beginning)...
1,000,000 / 4 = 250K annually
250,000 / 365 = 684 miles daily,
Which, if you /24 to get an hourly average = about 29 mph.
Mobil's video states the vehicle was running between 45 and 85mph during their extended test. These figures suggest the car was only running around half the time the test took... Could this suggest a daily cold-start? Or downtime?

It's too expensive and time consuming to run a real world test so you get something like this, instead.

Other than some squeaky strut mounts in the rear, my Camry at 224k miles still drives like a new car. Tight steering, quiet, and smooth.

I'm always skeptical of first party tests. Now if an unrelated independent engine shop did that same test without Exxon's knowledge,that'd be more relevant.
My car made it to 571k using bulk oil changes every 8-9k. Just saying. Still going strong at almost 576k after I took over the maintenance on it after buying it. Still squeaky clean under the valve cover, too. By the way, that test never actually states which Mobil 1 product they used. In regard to BigCahuna's post above, everything on the Accord still works perfectly fine, from the A/C to the heated mirrors and heated seats to the power seats and 6 CD changer. The underside is still extremely clean, especially for a Michigan car. All panels are original, down to the windshield and stone pitted bumper and hood.

Curious, did you buy this Accord brand new? Manual or Auto?

Wow that's hard to believe! How many transmissions did you go through on that Honda.. Post a picture of the odometer i would like to see that..

In a much longer time of ownership, my Mazda made it to 606K on various brands of conventional engine oil, with zero problems that could be blamed on the oil. The engine ran and sounded the same the whole way.

Their test are performed outside under cover. They do vary the speed and load placed on the engine. My own experience doing 10K OCIs with M1 oils for the last 39 years, has produced very clean engines, no sign of engine wear or increased oil consumption, and never had a lubricated part replaced.
