Is not most of what is reported simply from complex CC chemistry putting metals in solution, also EP sloughing off high load bearing areas?Once again, wear metals in UOA samples DO NOT reflect the rate of engine wear.
What does the "oil wisperer" suggest for the Ecoboost?Ive been reading about Navi’s quests and challenges. I don’t necessarily agree with his conclusions, but I don’t necessarily agree with his naysayers. I’m not qualified to give advice, but I get to have opinions. Funny that he mixes Subaru anecdotes with his Ecoboost experiences, as I have 2 similar engines: older Subaru EJ25 turbo and 1st gen 3.5 Ecoboost. But a few comments:
I have had the fuel dilution issue in the Ford. To those who say the workaround solution is to change oil more often, let me just say, I had one UOA done at a ~900 miles (hundred, not thousand) interval, and my fuel % from Polaris/Amsoil lab was ~4.7%, and viscosity was way below grade at 8.4. Previous 6000 mi OCI was 4.2% resulting in 8.2 cst. Subsequent 9600mi OCI had dramatically lower fuel and 10.4 visc...on different oil (Valvoline Premium Blue RESTORE 10w30). A more recent 7700 mi OCI (with an untested short off-season OCI in between) has confirmed the lower fuel and better visc with the VPBR. Only engine mod/repair were new plugs (std Motorcraft...newer spec) just before the more recent 7700 OCI.
I do agree the EcoBoost issues are not caused by oil, nor can they be resolved by oil (well, maybe some issues can be), but finding the right oil to “survive” those issues is something worth seeking. I feel really let down by the Motorcraft semi-syn used for 4 OCI’s (I assume), and the dealerships which performed those OC’s. Also underwhelmed by my (tested) results on PP and PUP. I don’t know which of these oils contributed most to the issues I had, but the best way I can describe things is the VPBR is cleaning up the mess left behind.
Makuloco’s video was interesting, though I’m not going to tear my engine apart now to put an aftermarket oil pump in. But I will look into the new API SP oils, however, I have 2 summers-worth of VPBR stash. Also the HP fuel pump discussions piqued my interest, as did mention of TSB 14-0040 and subsequent, though I don’t think it applies directly to my particular vehicle.
I think my approach is going to be 2 oil changes per year: one right before any big (7000-9000 mi) summer trip, filling with VPBR, and one right after the trip...more or less. I’m not sure what oil (something cheaper) for the off-season OCI. But it won’t be 5w40. The target off-season oil will hopefully be something that won’t totally undo the good the VPBR has done, and hopefully will be as close to Walmart-cheap as possible. M1 ESP 5w30 is a possibility, but it would have to be on sale...and again, this is probably for a ~4000 mi OCI. Regular M1 5w30 is also possible.
FWIW, I use “old school” Castrol Euro 0w30 SL in the Subaru. The “oil whisperer” I’ve been listening to doesn’t even hint at Euro Castrol (or any Castrol) being an option for the EcoBoost...and I asked. He doesn’t seem to like Shell (Pennzoil, Rotella, QS) either. Don’t ask me why. Maybe something EcoBoost-specific, or maybe a grudge; maybe he knows something about chemistry he’s not telling me. OK, he knows a lot about oil chemistry he’s not telling me. I’m afraid to ask for his advice on the Subaru. We’ve not discussed it.
That should be resolved by now. Also current ESP 5W30 has better ad pack than previous version.He would probably suggest I shut up, especially since I agreed to an NDA. But, hint, I didn’t discover VPBR on my own. Remember this, I had certain issues with MY EcoBoost, and he suggested it to address multiple issues. He also suggested I get Ford to fix the SOURCE of the fuel dilution, which so far I have failed at.
Now, I know you asked HIS suggestion, but here is something I have thought about (DEFINITELY NOT his suggestion): I liked Euro 0w30 Castrol in my 2007 Subaru (better than the 0w40 in there now). I wonder if it, or Mobil 1 ESP 5w30 would work well in the EcoBoost? What I like is their higher HTHS (3.5). Neither would be condoned by Ford though, nor Terry Dyson (the oil whisperer): the Castrol is SL rated, and I’m not sure how long ESP could be expected to last given gasoline quality in parts of US (that’s a question I have, not a statement).
Edyvw, Going a bit off-topic, but between those oils: Castrol Euro 0w30 & Mobil ESP (5w30...or 0w30), which would you prefer...in an Ecoboost or an older EJ25 turbo Subaru? The EcoBoost dumps fuel into the oil, and the Subaru thrashes it some other way.That should be resolved by now. Also current ESP 5W30 has better ad pack than previous version.
HTHS above 3.5 is way to go in Ecoboost.
I would probably go Castrol in Subaru. Stronger ad pack. Is that DI engine?Edyvw, Going a bit off-topic, but between those oils: Castrol Euro 0w30 & Mobil ESP (5w30...or 0w30), which would you prefer...in an Ecoboost or an older EJ25 turbo Subaru?

I think Renewable Lubricants was around fuel dilution. VW/Audi had those issues some time ago. I stay amazed how Ford and Honda managed to repeat same mistakes given that VW was guinea pig in DI approach.I don’t believe that particular Subaru was: 2005-2009 turbo...I don’t think. Yeah, on the Ecoboost, I was going to edit / add carbon build up and chain issues as challenges. Given your Euro vehicle “slant” or I should say “knowledge,” have you an opinion on Renewable Lubricants stuff? Supposedly holy grail for certain Audi’s. Sorry folks, I know Audi’s aren’t EcoBoosts, but share certain issues.
