What ever happened to the real world testing of oils? I remember when M1 tested a BMW and it went 1 million dyno simulated miles. I dont know about the rest of you, but I would like to see some side by sides done to see what we are really paying for.
Real world oil comparison

Me too - I would love to see a truly independent, double blind, multicar mega mile real world test. I guess the big holdback is cost.....what's in it for an "independent" to do this?
This is not a comparison but still interesting. http://www.mobiloil.com/USA-English/MotorOil/Drive/Drive_Around_the_World_Home.aspx
Real world testing, too expensive, I think. Plus any test would have to be narrow in scope and might generate more questions than answers. Those taxi tests? Do they apply to daily drivers? Not many for the time and effort spent. Are these type tests effective? You don't see them repeated very often and you don't see a long running ad campaign that keeps them in the public eye, do you? I think there are too many components to a maintenance plan to make oil of much importance, one way or the other. The people that sign the checks think more of pouring black yuck on a young lady in a drive-thru with the punch line, "more napkins?" That stunt was probably cheaper than a real life test and produced more predictable results. Would you not choose that oil if it would allow you to go safely through a drive-thru?
What is there to compare isn't Amsoil the worlds best oil?
Has Amsoil ever been tested in something like the M1 taxi test?

Yes it is an older but interesting test. Do a search the test is linked via other than our Amsoil guys so I did not add the link.

XOM has done two "real world" tests and provided the results on their website, which is being upgraded. JAG posted one of them.
I've always liked Mobil's approach to marketing. They list all the automakers that used/endorse Mobil 1 and product specs met clearly stated.

Mobil 1 has done a great job with their marketing.
Hi,
real world testing is alive and well - and on going!
Castrol for instance is still operating a fleet of vehicles (in the hands of owners) in a mix of applications (city, hiway and etc). This test programme in consort with VW as well has been running for some years and some of these vehicles have not had their oil changed FOR YEARS! On going Lab tests are running concurrently
One day the results may be made public - maybe not!
I have completed many many field trials since 1980 for both Mobil and Castrol in many engine families and in all sorts of configurations
Both sets of results of the last trials for both Companies - using semi synthetic and fully synthetic HDEOs - were made public and were well advertised. One lubricant, Castrol's Enduro LD 15w40, has been well recieved WW under various names including Tection
A 1m kms tear down inspection of one of my Detroit Series 60 engines was well publicised by Mobil here in OZ and elsewhere!

One thing I know is that Amsoil is constantly running and testing oils, ATF, gear oils….it's not a one shot deal, but constant in a wide range of vehicles.
If Castrol can make a VW last it must be a really good oil.

How often are oil formulations changed?
Maybe the R&D departments are working too hard.
It would be best I guess that the tested oils, in those formulations, are available for a while after the test results are published.

I would be up for real world testing. I've run Amsoil for the majority of the car's life and will be using nothing but ACD until the end. I plan to keep it until it's not worth selling and tearing the motor and trans down when it dies. Now I just need to find someone to do the same running the factory 5-20 oil.
I fully expect the clearances to be within factory new spec.

About 15 years ago Consumer reports did some taxi tests in NYC and concluded that "all api marked oils are about the same". Possibly not for super cold or super hot like trailer pulling.
That was probably 5 to 8 SL, SM, SH revisions ago.
So you would think super tech present day oil would be fine - but you may get better quality control with a name brand.

Im not sure Id consider the M1 test of the BMW 325I a real world test. They parked it on their roof and ran it on a treadmill for 2 years, so no cold starts and less intuitive into short trips. An excellent study though and was likely very costly.

It really wasn't much of a test. The cars were run a mere 60,000 miles. As you know, taxis are kept running almost constantly, so there was no cold start wear. Had they run them to engine failure, or 150,000 miles, or in some way pushed things to the limit, the results would have been more believable.
In their 1987 test they used a diesel injector and pump in test rig to shear the oils down. When they did that, the synthetics held up better.

Run a syn in a turbo, follow the schedule for severe vs "regular" service as regards OCI, and in 99.99% of all the vehicles built since rocker-arm V8 engines, you can run the plain old Dino oils if they stand up to API SM, and ILSAC GF-4 testing. You can run 0W20, 5W20, 5W30 and 10W30 in any engine you want(assuming post-rocker V8s), it ain't gonna matter. Real world is the engines last so long the body rots and rusts, the suspension goes flat, the electricals surrender, and the frame weakens from age LONG before the engine wears out, assuming a reasonable OCI appropriate to your service.
You oil-wizards correct me if I'm wrong, but under GF4/SM, aren't we talking 90% synthetic performance even in a Dino, no matter the brand?
