Valvoline 4-year 500k conventional vs synthetic engine tear down

[SumGuy]

I just stumbled across this. Posted 2 weeks ago:



They should have done a compression test, maybe leakdown test, maybe a crank friction measurement before tearing the engines down. Would like to see fuel efficiency comparison between the 2 engines (they no doubt have tracked fuel usage on the 2 vehicles, I would think). That would be very interesting to see for the average civillian if synthetic oil gives better milage.

It has been posted here on this Forum. Looking at the picture, I am just wondering how much cleaner that engine would have been if it had been using 1 these Oil's.

1) HPL
2) Amsoil SS
3) Mobil 1 ESP
4) Mobil 1 FS

I searched titles for keywords but didn't see that it might have already been posted.

Some comments in the video - they are surprised that the conventional oil survived a 10k change interval. About all they could say in the video is that engine wear was good for both oils, so who cares about deposits and varnish? I still say show me fuel economy numbers for those tests. That is something you can sell to the public.

For the Ecoboost engines I wouldn't go over 3K with the blend and 5k with the full synthetic

I was just told that my post was a copyright violation? Because it contained a link to a youtube video? The same video posted in a different thread on the same topic on Aug 31 ?

No, that's not correct.

Considering they just sat on a dyno for 4 years running straight - always at operating temperature - they both look like crap to me.

Not sure if that is indicative of the oil or the engine or both.

Meh.

I won't comment on the oil but must say that I was impressed by how easily those DEWALT power tools disassembled those engines. My pneumatic tools are feeling a little threatened right about now...

Need to do it again but cut the conventional OCI in half.

Did they say in this video, like I seem to recall in the M1 tear down, that there is no measurable engine wear using the synthetic? Did they mention which oil filter they used?

Meh

Likely much cleaner IMO.

User subieroo proved otherwise on his eco boost.

Did they check for ring / bore wear?

 

[buster]

Not sure this a favorable video when the conventional had 7 stuck rings and the synthetic had 1 stuck ring. That's terrible LOL.

See: 12:30 min mark.

Would Valvoline Extended Protection and Pennzoil Ultra Platinum have similar results?

NYH.

It's indicative to me that 10k oci is stretching it on these engines, Most use cases will be more severe, with multiple cold start, oil levels not monitored as closely etc, a good amount of idling thrown in aswell.

though at 500k, that engine owns you nothing so there's that.

They hinted to extending the interval, likely to push for a failure as the test was taking too long. But I wish they elaborated on that: how many longer intervals did they run....
