My mistake, it wasn’t bfleeman, it was @thirdgenlxi and he was using Motul 8100 Eco Lite 5w30

Any EcoBoost may have fuel dilution, that would punish the viscosity. Blackstone can’t report fuel accurately. Try Oil Analysers lab or others, who use actual gas chromatography to determine fuel. Unusual to see Motul used in a F150 EB. @bfleeman does (or did), his results were excellent...

Gee, doesn’t look like mixing 2 different oils caused much problem. FWIW, I contacted HPL about blending those 2 weights of their regular PCMO, though in different proportions, and in different motor, and their spokesperson advised against it, but admitted, if I were going to mix 2 oils, that...

Per OP: “used one of the dreaded leaky Fram Endurance filters during this OCI.” Is this a known thing? I just bought a couple, thinking they were the very best out there. BTW, obviously, this oil did fine, and in Texas probably not a concern that it is so thick. A non-Euro 0w-30 or 5w-30...

I’m out of town, maybe for up to a week or so, then need to get at least one of my Subaru’s operational (both are down at moment. I’m down to a Ford Transit van as only transportation). Then, more out-of-town family obligations (I won’t share details). No pictures until BMW emerges from...

Thanks, I will need it. Slow progress, now distracted by more pressing issues. But, I appear to be following or planning to follow the general consensus steps, so thanks for those tips so far. However, bought some cheap Delvac HDEO CK / SP 15w40, since it won’t be in the car for very long...

Let me confirm what I think you said: Though GM says Dexron VI is backward compatible, you’re saying I should use the Dex III instead? Still somewhat confused as there is a “Delco Gold Type III” which I guess is Dexron III??? I want to save money on the initial fill, because as soon as I can...

Bentley service manual (printed ~1991) says * for the power steering, Dextron II…yes, 2! * Dot4 brake fluid. * manual trans needs SAE 80 fluid. Then has a little chart that shows viscosity needed for temperature range, but doesn’t include anything above 40 (???). Weird. ***** Re the PS, it...

Thank you for responding, and I believe you’re right, I just needed to be talked into going the extra step. I am trading one risk for another: the risk that I muck it up, vs that it’s already mucked up inside.

Thank you, I’ll check it out.

Well, now I feel like a tease. Yes, I have this car. Yes I intend to get it running and sold. But I’m just beginning to be mobile myself after breaking my leg & ankle. It’s been miserably hot here, and there are several other projects ahead of this. Some quite big. And the car is ‘boxed...

I guess my question got lost in all this: would it better to risk dropping the pan to get a look at sediment and oil screen/filter changing last 4 qts in process, or just avoid risk and just swap in the last 4 qts I have (for 77% oil change) via drain & fill. 2 ways to swap in the last 4 qts...

118k. I’ll work on getting pictures. 10 yrs of dirt and being ignored. Dang it, I meant to wipe dust off off color label, but blue leather, silver-blue exterior…will get actual color off sticker under hood, was just too focused on figuring out how to pull plugs if the fogging oil is a good...

OK, general topic probably already covered somewhere but multiple questions about how to bring a 1987 535i back to life, after “sitting” for 10 yrs. OK, it’s my “barn.” For years I would at least fire this baby up every so often to keep the motor lubrication condition in check, but that lapsed...

As a fellow Subaru EJ turbo owner, I second the notion that Castrol Euro 0w30 is awesome sauce for our engines. 0w40 probably also OK. Not sure which boutique options would do better. I’ll pay extra to not use Mobil 1 or Pennzoil in this engine family (at least the turbo’s). Local tuner...

Any thoughts on my transmission or the UOA results?

What??? Pretty sure there are plenty of 75w-85 synthetics. Can you name some non-synthetics? I don’t pay attention to everything, so maybe you have a valid point, though perhaps overstated. Redline, HPL make 75w85….i presume synthetic. I THINK Motorcraft 75w-85 is full synthetic. If you...

Keep your transmission fluid clean…ie change it on some regular schedule, and people appear equally divided between genuine Mercon LV vs boutique (the top HPL guy sure was proud of his green ATF, which rumor has it, is “battlefield-tested” in a largely Ford fleet at our southern border, but that...

New style? Does that mean no wire backing? I’m just trying to catch up / keep up with the many changes. Edit: I found this thead first, didn’t realize he’s been CP’ing these for some time now, multiple threads, and one of previous threads had mention of no wire. Correct me if I’m wrong.

Try using Oil Analysers, WearCheck, or TestOil instead of Blackstone. Get a real fuel dilution reading, not a fake estimate. I wouldn’t try to dissuade you from a euro oil. People seem to give this engine a pass on thin oil, given other iterations of it spec’d xw-20, but IMHO you will be...
