I would just add that 4A seems to behave differently in slippery, sport, normal, or other GOAT modes where it is available. For instance, if watching the “power distribution” gauge on the instrument cluster, you can notice 4A + slippery sending power to all 4 wheels with an even split almost...

yeah, where I live (near the ocean) we almost never get below -20F and 5W should always be good for that. Anything more than about 100 miles inland and you need block heaters even with 0W since -30F is a regular thing. With positive displacement oil pumps supposedly there is no downside to a...

My last oil analysis with VRP 5W-30 came back at Fuel dilution over 5% and viscosity 8.3 cSt. I dumped it at 900 miles in my wildtrak as a preliminary flush run so the next 5k mile analysis will have less residual. We are having a fairly brutal winter with below 0 cold starts being the norm...

So that was a 2,000 mile (since last oil change) analysis? Why’d you sell? Another vehicle catch your eye?

Did my Front and Rear diffs and transfer case for the 3rd time at 30k miles last night, after having done them previously at 3k and 11k. Despite a few 2+ ft water crossings the fluids all looked fine. Will probably just do this every 30k or so from here on out, along with the transmission...

yeah that makes sense. Going down the rabbit hole on ILSAC oils and how the .gov require that the US automakers recommend thin oils for minuscule CAFE/fuel economy improvements at the expense of wear protection is a fun time. The Euro ACEA licenses are no panacea either but at least the euro...

Not sure what Motul Oil 5W-30 you picked but a => 3.5 HTHS MB229.51 or Porsche C30 oil would probably be a good choice with so much dilution, maybe even a C40 (0W-40). What was the resulting oil viscosity? Probably down around 8 cSt? If you are short tripping < 5 miles daily, I would...

Wow, 2.3 or 2.7L engine? Can you post a copy of the report? I have usually only seen Horizon/Polaris/OA analyses say >5% and not give an actual reading if it was above that, would be interesting to see yours. Usually I see the >5% on Hondas but I’ve seen it on a few gen 1 3.5L ecoboosts too.

I was thinking about your fuel dilution: do you think living in Colorado at high altitude could cause the engine to run higher boost more often and therefore have more dilution, than say someone like me at sea level where it is usually cool/cold (denser air)? Also, going forward, what are you...

For some reason the coolant gets low in the first few thousand miles on many/most new broncos like was said above, on the 2.7 and apparently the 2.3. Maybe it is purged air as mentioned, I don't know. Both of mine did it and have held steady for about 15,000 miles since adding about a quart...

The Air Filters become more efficient (better) as they get dirty. At some point they will start to restrict intake flow too much though. I’m not sure why the OEM pleats seem to get spread apart like that, probably not ideal Diesels have a spot for a gauge so you can tell when they actually...

Solid choices! Premium Guard also came out with a new “Ultimate Synthetic” line of oil filters a few weeks ago. Efficiency is specified as 99.5% at 25 microns which is pretty good, with “superior flow” and a 20,000 mile rating...

I can tell you I’ve done about a dozen oil changes on two different 2.7 broncos and the “IOLM” has never done anything but countdown from 1 year or 10k miles. I am skeptical that it does much else. If it does, it must take egregious abuse like sustained oil temps over ~250F or sustained RPM...

I can pretty much promise the Bronco isn’t doing any kind of chemical analysis on the oil to feed to the oil life indicator. That would be awesome if it was true. It counts down days and miles from last reset, divides those numbers by 365 and 10,000 respectively, subtracts from 100 and...

If you went out and checked it right now and counted down mileage from your last oil change, or % into 365 days, what does it say? I am in a pretty cold place and do plenty of sub zero starts, never seems to go down faster. I believe some oil life algorithms can be complicated, I just don’t...

Do you think it actually looks at cold starts and idle time? I think it is just 10,000 miles or 1 year in Bronco. If you drive 100 miles or wait about 4 days it drops oil life remaining 1%. I have varied the amount of idling and cold starts quite a bit between oil changes and the oil life...

That stinks! The stated policy of Oil Analyzers is to not test the fuel dilution if the oil viscosity is within 1 cSt of the unused oil. If you told them it was 0W-40 I’m sure they would’ve tested it, did you put 5W-30 on their form? (I know you were mixing which complicates the form). I...

PUP seems to be doing really well well for you with the 2.3L. I bet Analyzers comes in at ~2.5% dilution for this one.

So, I changed the HPL P+ 0W-30 engine to M1 AFE 0W-30 "normal oil" for about 3 hours/64 miles and took some more pictures. It looks like all that tint in the original HPL pictures was in fact the molybdenum coating from the "Molyvan 3000" (and apparently other molybdenum additives) top treat...
