Is this the same offering as: Post in thread 'HPL PCMO 5w-30 (Base) VOA' https://bobistheoilguy.com/forums/threads/hpl-pcmo-5w-30-base-voa.383965/post-7079679 I guess they liked something Castrol was doing (hint: Ti). Also, that sure is a lot of Silicon…both new and old versions. Assuming...

So, hold it! Title says PCEO 5w30, but UOA says HDMO. Your subsequent VOA’s seem to support this is the PCMO version, not the diesel version. Could you clarify? Just so we can be sure. “Low end”PCMO? (Not that any HPL’s are really “low end”).

Some slow progress, but with fresh oil, fresh power steering hose and fluid , battery installed, the engine turned over and sounded quite decent. I had disconnected the coil, and siphoned the gas tank, so didn’t expect ignition. May have to address coolant as well, but added (mere) 1/2 gal of...

I used the Gen1 for maybe 4 or so OCI’s in a Ford Ecoboost 3.5 (1st gen), And thought it did very very well, though a bit concerned with high copper PPM. It held up well to the fuel dilution, and delivered fairly good wear numbers (except copper). No OTS Walmart oil could compare (though they...

I would like to hear from @edyvw about this vs Castrol euro. I’ve become a bit of an Amsoil & HPL fanboy, but still want validation before I express my fandom. Oh, I am also a Castrol Euro 0w30 fanboy…though concerned they have or will make it a mere shadow of its former self.

Well, wish I could edit last night’s post. No frankenbrew originally intended. but HPL had a Black Friday sale last fall after I started this thread, so I bought one quart of the EC40. But today or tomorrow, need to decide whether I should run straight Delvac 15w40 (I have enough) or mix in...

Lazurus bump. Updates coming. I had another major injury last September which delayed all efforts. Now recovering. Today, just repaired power steering hose leakage/deterioration. Also drained 10yr old oil (probably castrol GTX 20w50.). In was Mobil Delvac 15w40, which will be probably be in...

I would have thought Amsoil XL had high-end additives / modifiers, but used Grp III vs more Grp IV / V as in the SS. I mean, what would be left to scrimp on in their OE line vs XL?

I’m sure this has been discussed elsewhere, but really tired of 5w30 oils (including Amsoil) dipping from grade, not just to the boundary between it and xw20, but well past (this XL dipping to 8.7ish, well below the true boundary between the grades). I’m not concerned about 0.1 difference, but...

The phosphorus and zinc are kinda weak. Calcium / Magnesium also weak. The viscosity is nothing to brag about. Yes (current) wear is admirably low, but this oil is not the best. How long do you want to keep the vehicle, or in what condition do you want to sell it? Upgrade to PUP xw30, or...

You already know at least as much as I would hope to learn, and maybe you are smart to keep your next interval (on ESP) under 4k just to “learn” how ESP will perform, but I would hope you can go 5k + once tested. I’ve asked both Amsoil and HPL about using euro oils in my Ford Ecoboost (also a...

Personally, I look forward to seeing the ESP UOA’s, if you are planning to share them. I would think you can stretch the intervals to twice per year. Surely. (Er, Hopefully). It’s irrelevant, but I’ve stretched my 07 EJ turbo intervals to close to 5k, and still getting great results…that is...

Hmm, interesting. I guess I should get myself more up-to-date. Noise and vibration suggest the oil is shared (like Eaton design). Emphasis on “suggest.” If so, that noise and vibration could be due to friction modifiers, which are near ubiquitous in 75w90’s nowadays. (Lots of threads on...

@zeroptzero if your Subaru specs 75w85, it is newer than anything I have direct knowledge of. However, back in the day, the Subaru Torsen rear diffs were sealed units, and the gear oil you could change did not affect the Torsen in any way. If the fluid inside the Torsen itself ever failed...

I have 3 vehicles (complaining not bragging). I have Motul in 1, SVG in the 2nd, and HPL in the 3rd. So I wasn’t trying to diss any of those. I based the decision in #2 & #3 on Subi’s Mega thread. #1 has had the Motul in for awhile, since before the thread, but maybe only 15-20k miles, if...

Uh, correction, the Amsoil SVG had the lowest KRL in your tests. Or am I misinterpreting the tables?

Which Castrol, just curious. I now have a 3.6 in addition to my EJ25 turbo.

Not direct injected. Doesn’t mean it can’t have fuel, but not prone to. But why argue over Blackstone bogus fuel/flashpoint results. Ranger’s results don’t look too bad. Not sure, maybe the Roltella is “old” formula, which is dual-rated, or the newer Rotella is just as good for gas engines...

This used to be the “darling” oil for turbo Subarus of your vintage, so why not the EZ30? but back then, this was a dual-rated gas-diesel oil. Later on, Shell (Rotella) dropped the gasoline ratings, and I assumed it was no longer a darling for our boxers. Well, nothing in your UOA backs up my...

Hi Vorlauf. I was thinking a couple of the WearCheck fanboys would see the question. I’m assuming the “method” is Gas Chromotography (GC), but that doesn’t mean the standard is the same as Oil Analysers’. Not saying OA’s is the best, more just trying to determine if the results are directly...
