    AMSOIL Signature Series 5w-20 5.3k mi; 2019 Silverado 64k miles - used oil analysis

    Does your Silverado specify Premium? I have a TGDI (Ecoboost) in my Transit…different beast, but if/when I go into the mountains, supposedly (per owners manual) I’m supposed to use midgrade vs regular (to stay at/above 87 octane)…regardless of elevation…Ford does suggest premium for towing...

    2016 Suburban Valvoline Restore and Protect 5,500 on oil, 113,000 total miles - used oil analysis

    Wow, yeah, Terry or not, I liked the TestOil lab…and I guess Terry was either sugar on top, or vinegar (😂🤣). But, I have to ask, if you can remember, your 8/14/2019 report was either NOT xw20, or there was a lot of thickening. Surely Terry said something about that

    AMSOIL Signature Series 5w-20 5.3k mi; 2019 Silverado 64k miles - used oil analysis

    Sorry to hi-jack, but what does this “spiking” do for you?

    Ford 6R80 transmission fluid changes

    Wow. Motul is well-respected around here, but I have zero experience or even hearsay about their ATF. This is my suggestion, but I am not a guru: more or less repeating what I suggested before: Assuming you still have 10qts of OEM Mercon LV, and assuming you can buy additional for $13-14...

    Ford 6R80 transmission fluid changes

    Suresh, I bet you understand the difference between licensed fluids vs “recommended.” Are there any “licensed” LV fluids easily available to you? Castrol, Pennzoil, and even Walmart’s Supertech (from Warren) had “licensed” Mercon LV fluids at some point available in U.S. Supposedly, the...

    Ford 6R80 transmission fluid changes

    I have some direct experience with the 6r80 in a 2015 Transit 250 van, and a lot of hearsay, so take it for what it’s worth. It sounds like you know at least as much as I do, so reading this is probably doing you no real good, other than encouraging you to keep trying. It sounds like each time...

    2023 GMC Canyon 2.7L L3B TurboMax (15,261 mi), Amsoil Signature Series 5W-30 (5,318 mi), 3rd oil change

    disc material?? I think I should reset how my comments sounded. I DO think you have addressed your transmission sooner than 99% of people, but that may be a good thing, especially given what you found. It is theoretically possible many transmissions have this “swarf,” but the transmission...

    2023 GMC Canyon 2.7L L3B TurboMax (15,261 mi), Amsoil Signature Series 5W-30 (5,318 mi), 3rd oil change

    And I thought I worried too much. I can’t comment on your transmissionmission “sand,” but your motor seems fine. it’s too early to expect all “factory swarf” to be completely gone yet. On your transmission….i don’t know, maybe normal “factory swarf” there as well, or maybe not. Does GM say...

    Not all Premium Guard / MicroGuard filters are created equal...also Wix XP versus Microguard Select

    Thanks. I almost bought some Pentius online, but Advance Auto had a sale (don’t they always?) and I got several Premium and EP instead so I am good for awhile now. Of course, I still manage to fret about the one for my Subaru, as the CQ valve pressure relief setting doesn’t match the high...

    Not all Premium Guard / MicroGuard filters are created equal...also Wix XP versus Microguard Select

    aren’t some Pentius filters also “in the club?” And for Carquest, is it just their Premium and Premium EP, or are any lesser Carquests in this club, or just those two levels?

    impulse Mobil 1 ESP 0w30 buy - use in what vehicle?

    My reasoning could be flawed, but is: If engine not warmed up, all oil is thicker than optimum. No need to make matters worse with an “even-thicker” oil. One thing I like about the AMSOIL Signature Series, it’s viscosity at 40C is thinner than many. I have no idea how thick any oil is at 0C...

    impulse Mobil 1 ESP 0w30 buy - use in what vehicle?

    Sorry, “Life” interjected recently, not that anyone actually missed me. 4 things to add (or repeat): 1) the soonest this ESP will go in anything is a year from now. I just changed oil(s) before this purchase. The Subie got AMSOIL Signature Series 5w30 and the EcoBoosts got HPL (mostly 5w30...

    impulse Mobil 1 ESP 0w30 buy - use in what vehicle?

    I did get some useful info from this thread. Thank you to those who provided such. One unexpected thing I learned is that one of the underlying questions I had was covered in a Mobil 1 Extended Performance vs Mobil 1 ESP thread that I had not seen before. So to the poster who questioned my...

    impulse Mobil 1 ESP 0w30 buy - use in what vehicle?

    Well, if you don’t mind, if you would, go back and read my 2 use cases (mostly short-tripping Subaru H6, and intermittent RV use, on-road off-road in the Transit Gen 1 EcoBoost, running 8k-10k between OC’s trying to avoid getting oil changes mid-trip in small towns). Then tell me 1 or 2 oils...

    impulse Mobil 1 ESP 0w30 buy - use in what vehicle?

    Thanks. Yes, it’s possible Valvoline Restore and Protect would have been smarter for the Subaru, but, hey, cheapskate (if the rebate comes through). I bought this “low mileage” 3.6, but now it appears it had a rougher previous life than I previously thought. Hence “cleaner oil” might be...

    impulse Mobil 1 ESP 0w30 buy - use in what vehicle?

    Yes, I know, I was trying to be cute. Hoarder: I just changed oil in both vehicles. So the earliest this Mobil 1 ESP would be used is late this year, or hopefully this time next year. Plus I already have some HPL left, probably enough for the Transit, but not enough for the 7 qt Subaru...

    impulse Mobil 1 ESP 0w30 buy - use in what vehicle?

    Thanks for replies, so far. I tend to agree the Subaru running a thick Euro oil is unnecessary (maybe even inappropriate), certainly not sure it would be beneficial in ANY way. I think it would have been great for my EJ25 turbo, but I just sold that baby. The H6 motor is new to me, and I...

    impulse Mobil 1 ESP 0w30 buy - use in what vehicle?

    Here is the point of this post: to ask if there is anything about Mobil 1 ESP 0w30 that is suboptimal for either of my 2 vehicles, and their use case: One vehicle is 2013 Subaru 3.6 Outback: not DI, not turbo, and driven mostly short trips. An annual oil change should be more than...

    Carquest Premium 84502 used oil filter cut open - in service 12k miles

    Heck, I would rather run that used filter (pre-cut) vs a new Fram Ruffles filter. Interesting that I recently saw a Fram Toughgard on the shelf in a home improvement center near my house…in a size I could use. Was tempting. Assuming Toughgard was pre-Fram-implosion. Still, wasn’t really any...

    Carquest Premium 85372 used oil filter cut open - in service 6k miles

    Look, patriot claims aside, this is one example of when we could, maybe should, embrace foreign products. At least the good ones. Compare to Fram / Mann Hummel (is that even USA?). I know that I don’t know how crappy it must be to be an oil filter builder/laborer, but the Korean / Vietnamese...
