Read a lot on here about ecoboosts needing synthetics because of the turbos. But jump over to the hdeo section, and guys getting a million miles running conventional rotella or delo. When I had my deisel I ran what ever was on sale, mostly 10w30 rotella, and never had an issue. Why does it seem conventional is fine for a Kenworth hauling 100k lb down the highway, but not for a little 6 cylinder gas jobby bombing around town
Ecoboost and synthetic oils.

Just because you read about Ecoboosts needing full syn oils because of the turbos doesn't mean it is so. There is lots of regurgitating . Syn oil ,the common brands at Walmart aren't that much more expensive than the "conventionals " if that means anything. I would thing all the semis would be running syn oil if there were benefits for the $30,000.00+ engines. Wehave some owner operators and fleet tech posting on this site.
Maybe the big rig turbos run a little cooler...overbuilt to last, while the EB engines have a smaller turbo to both fit and provide high power, so temps may be an issue.
Or perhaps Ford decided that some owners wouldn't change on time, or that conventional wasn't up to the 10,000 mile interval, or both.

Valvoline and castrol conventional meet the Ford spec for ecoboost. Maybe others, but I never looked at many other jugs

Besides the heat, put 44 quarts in that Ecoboost and see how long you can run an OCI.

For me oci is a non issue, change yearly. I have an F250 truck from work that is my daily commuter, wifes rocks a 2013 Fusion for her daily life. On the 5.0 i traded in I put 20,000km on in 3.5 years.

Ford recommends Motorcraft semisyn 5w30 for the f150 Ecoboost engines, so guess you could say that full syn is not really necessary. Ford doesn't seem to think so.
There are some conventional and most semi-synthetics that meet Ford's requirements for the Ecoboost engines. Those who claim a full synthetic changed frequently is necessary have to my knowledge never produced facts to back this up. There are however lots of UOA's with semi-synthetics in Ecoboost engines on this site showing they are more than adequate.

You are mixing apples and oranges. By the way, run conventional oil in new diesel and see what happens with emissions system.

the big 18 wheelers use a lot of oil, while EB engines use a few quarts. please tell me which one will degrade faster

How big is oil cooler in 18 wheeler? There is much more space to put much more and larger hardware. On top of that, diesels dissipate heat much faster.

Indeed, HD OTR trucks get brought into interesting analogies ... Our fixed position diesels hold 440 gallons each ... maybe I can make that into an 18 wheeler analogy ...
Turbos aren't as hot as you think. The TEOST test's failure to predict turbo deposits in water-cooled & oil-cooled, with thermal siphoning at shutdown turbos, like the Ecoboosts have, have been discussed over the last couple of years on bitog. The latest discussion is at https://bobistheoilguy.com/forums/ubbthreads.php/topics/5030680/1

just my own observation - even syn oil gets chattery after 3-4000 miles in mine. timing chains are harder on oils and fuel dilution could be a thing with these. Mine hasn't shown oil loss on the dipstick since passing 1,000 miles (it alarmed me with 1.5 quarts consumed in the first 1,000), but no loss + increasing noise makes me wonder if dilution is a thing. I haven't bothered with getting UOA but probably won't wait to 10,000 OCI per the meter to change it. Probably 7500.
Once it's past warranty I'll move to a 10-30 oil, due to past engine family history with chain guides.
With intervals like 7,500, I'm not sure if a syn really buys more than piece of mind.

Diesel EGT is generally limited to 1250 deg F. Gasoline engines may see as much as 1700 deg F.

Clearly liquid cooled turbochargers hold up well. However, it's good to know that UOA results will not tell you if the turbine seal is coking up. Such coking is largely prevented by the choice of a quality synthetic.
There have been plenty of Ecoboost turbo's changed due to coking. I won't claim "it will happen to you" if you choose conventional oil. I will claim that the added expense of synthetic is minor compared to the cost of coked piston ring lands, or turbocharger hot side coking.
In general, the EB turbo failures were related to towing and oil coking. Remember, the liquid cooled housing does not cool the turbocharger shaft. Modern turbochargers are simply designed to be tolerant of some coking. I'd rather not have any coking.

^^^ That. Only modern gasoline engines with stoichiometric tuning at WOT can go even hotter. I have heard about engines that go as high as 1920 F.

Ford recommends up to 10K on "conventional". The difference between a group II/III blend and a group III is small.

Yeap, the owner's manual for our 1.5L Ecoboost Fusion spells out "when you should expect" the oil life monitor to notify you. For severe duty it's around 5000 miles as I recall and for normal usage, it's 9000-10000 miles. Of course, everyone believes their conditions are "severe" but my wife drives to/from work 10 miles round trip and running errands and it still runs out to 9000+ miles before it says the oil needs changed.
