    Get ahold of Mary Jane at ADVLubrication. I’ve heard they make it, just may not have it on the website.

    Gear Oil at 20,000 miles in Ford 9.75” Diff

    I’m glad you survived all that! Shoulder surgery is nothing to sneeze at, that’s for dang sure. During the first week, I couldn’t put deodorant on my right armpit and had to rest my left hand on the counter and lean away to get enough space to coat my left one. It looked goofy, but worked, kind...

    post your latest differential fluid change

    I made a post on it, but figured I’d contribute here for posterity’s sake. 2014 Lincoln Navigator L 4x4 Ford 9.75” IRS Differential Out: 2.5qts Amsoil Severe Gear 75w-140 with 20,000 miles on it. In: 1/2qt HPL Differential Cleaner. 1qt Amsoil SG 75w-140, 1/2 qt Amsoil SG 75w-90, 1/2 qt Amsoil...

    Gear Oil at 20,000 miles in Ford 9.75” Diff

    Brother I barely get that sort of MPG completely unloaded with this old beast 🤣. It averages about 12.5 unloaded and about 7.5 when towing the camper.

    Gear Oil at 20,000 miles in Ford 9.75” Diff

    Well I should have spoken to Dave then, lol. He and I have chatted about the results in the primary chain case in my Road Glide. I’m wondering if the Ford spec for mine using the 75w-140 is due to the loads placed on the gears when towing? I’m pulling 7000-8000lbs behind my Navigator with my...

    Gear Oil at 20,000 miles in Ford 9.75” Diff

    So this may be a miscommunication on my part. That “frankenbrew” of gear oils is all Amsoil with the exception of 1/2qt of HPL’s Diff Cleaner. I just used up the last of my remnant bits of SG as a carrier for the HPL Diff Cleaner. I’m certainly not planning to use this blend with the cleaner in...

    Gear Oil at 20,000 miles in Ford 9.75” Diff

    Ford specs full synthetic 75w-140 for this diff, unsure why. I know that during the first few years of F-150 production they spec’d 75w-90 and wrote a TSB bumping the visc to 75w-140 and carried that forward to all production years since. 🤷‍♂️ It was an extensive surgery. 90% torn from the...

    Gear Oil at 20,000 miles in Ford 9.75” Diff

    Hey Subie! 75w-140 is the Ford recommended fluid for this vehicle and differential. As for the mixing, it isn’t going to stay in there relatively long and the Ams 75w-140 was the only 140 gear oil quart I had. Now all I have left is some Royal Purple 75w-90. It’ll be in for only a few thousand...

    Gear Oil at 20,000 miles in Ford 9.75” Diff

    Hello again, I ordered 6 quarts of HPL 75w-140 and a quart of HPL’s Differential Cleaner. I’m two weeks post shoulder surgery, spending too much time on the internet reading BITOG and buying HPL, lol. I decided to drive around for a while then crawl under my ‘14 Navigator, crack the fill plug...

    ULV mercon for ford 6R80 ???????

    I second this. I will add, wear a long, thick rubber grill glove when checking the level. I’ve got a nice manly burn scar on my arm from just brushing against that running cat for a microsecond.

    2014 Lincoln Navigator 5.4 V8 ~150kmi, 5000mi UOA AMSOIL 5w-20, TBN depletion?

    Mind if I pick your brain a bit? I’m still learning a lot about oils, bases, add packs, etc. What is the purpose of boron in an engine oil and what does its depletion signify? I ask because I had a 2019 Honda Odyssey and it depleted the boron in the Amsoil I used in it as well, and that was the...

    2014 Lincoln Navigator 5.4 V8 ~150kmi, 5000mi UOA AMSOIL 5w-20, TBN depletion?

    Addendum to my last post. Per this VOA of Amsoil SS 5w-20, the VOA oxidation is 47. https://bobistheoilguy.com/forums/threads/amsoil-signature-series-0w-20.366584/#post-6424703

    2014 Lincoln Navigator 5.4 V8 ~150kmi, 5000mi UOA AMSOIL 5w-20, TBN depletion?

    Honestly, I like Amsoil and consider their entire product line top notch. It just didn’t hold up well in my application to give me confidence running it again. For some reason, the oxidation level was seemingly very high (though I admittedly don’t know what the VOA ox level is) and the TBN got...

    2023 HD Road Glide Limited. HPL V-Twin 20w-50. 7400 mile analysis.

    You’re far too right. I was thinking “you know, I should be good to go by then! I’m at 2 weeks post surgery today and have almost my entire range of motion back already!” after thinking for a while I had an epiphany and thought “sure I can ride, but if I drop that behemoth, I don’t think I’d be...

    Man I hate to hear that. I feel your pain though. My doc did a fantastic job and the anesthesiologist did as well, I’m just a very fast metabolizer of medications/alcohol/etc. How are you healing up now?

    2023 HD Road Glide Limited. HPL V-Twin 20w-50. 7400 mile analysis.

    Thanks a lot man. It’s proceeding well. I talked with the owner of Lock and Lean and he suggested I take the training at a later date. The nearest date after the Pensacola one is October 18-20 in PA. Having spent my youth in a nearby state and visited Philly a few times, I decided to train...

    2023 HD Road Glide Limited. HPL V-Twin 20w-50. 7400 mile analysis.

    Update: Bike has 12,000 miles on it. Changed with another run of HPL V-Twin 20w-50 at 10,000. Im currently down hard after a surprise emergency shoulder surgery August 26th (day after my bday). The VA did an MRI of my left shoulder after physical therapy failed to improve my pain and...

    2014 Lincoln Navigator 5.4 V8 ~150kmi, 5000mi UOA AMSOIL 5w-20, TBN depletion?

    Hey everyone! Update for you, I just ordered 4 gallons of HPL PCMO 5w-40 since I’ve run out of the last of my HPL 5w-20 on this last change. I had to get a timing service, new water pump, and the Melling high volume oil pump installed on the Gator at 159,000 miles. I had put the HPL 5w-20 in...
