I’m using studded Duratracs this winter, set to 32 PSI cold. They are OK, nothing spectacular. It is still pretty easy to slide the back end out in 4A while in an icy roundabout at ~15 mph. Better than the 30,000 mile worn in stock Goodyear Territories. Their main advantage is less stopping...

Yeah. What wasn’t clear to me in the original post is if you noticed the low oil level when you first purchased the vehicle (before you changed the oil) or if it was low after you personally changed the oil. If you saw it low before your oil change I’d guess that it was just under filled by...

I’ve cut open most of my oil filters in the dozen or so oil changes I’ve done for my two broncos and there are always some sparkly flakes on the filter media. Most of the time they aren’t magnetic which probably means they’re aluminum. The engine’s front cover, lower block, and pistons are...

Yep, and I have found that a no VII, shear stable SAE 30 oil will only decrease about 0.3 cSt per 1% fuel dilution. For ESP 12.2 - (0.3 * 5) =10.7 so that checks out. PQIA claims Motorcraft 5W-30 starts at 11.1. 11.1 - (2.5 * 0.3) =10.35. So the Motorcraft appears to be shearing by 15% in a...

I agree, 7 would put me over max level (top dot) by at least 1/2 qt. As I understand it overfilling can have adverse implications for the PCV system. 1/2 qt over is probably not going to matter like you say, but overtime overfilling can send more oil through the PCV valve, leading to deposits...

I let my oil drain for 20 hours overnight last time. I even jacked up the driver side and used a MityVac to suck the pooled up residue from the bottom of the pan. Then Measured 6 Quarts into a graduated funnel during my last change in case you don’t trust the Mobil Juggalos to measure...

Yeah, I have heard of phaser failures on Broncos before 5,000 miles since new. Hard to say if oil really plays a role if it can happen that soon. I would guess on higher mileage engines, oil quality can affect the cleanliness of the oil screens for the phasers and play a role. The VRP really...

It might be worth a try to use VRP, I would if I were you! It has been shown to be most effective at targeting piston ring deposits so far and I’ve seen a few try to use it for heavy varnish removal like yours where it didn’t seem to move the needle much after 20,000 miles. Restore and Protect...

Valvoline (now owned by Saudi Arabian company Aramco) definitely has their own engine lab in Kentucky as does Mobil in New Jersey (maybe others too). These companies are allowed to self certify their oils to meet various industry approvals like API SQ, Ford WSS-M2C961-A1, etc. Mobil has the...

Yeah, I’m going to do a short, 1000 mile oil change interval with a “normal oil” (M1 AFE) in the HPL engine to make sure the red/brown residue is just a benign moly coating and not any kind of varnish precursors or depositation. I have been assured that it is not harmful and should rinse off...

I have 2 Broncos with the 2.7L Ecoboost Engine. The first Bronco (Valvoline Restore and Protect) was purchased new in October 2023. At time of these pictures (two days agoa) it has 36,456 and has the following oil change history: 0 - 6914 miles - Motorcraft Synthetic Blend 5W-30 (factory fill)...

Bottom was run on Motorcraft for ~500, M1 AFE 0W-30 for 14,000 miles changed at ~3k intervals, then HPL put in it at 14,500, 15,000, 20,000, 25,000 and now sits at 29,000. Top was the same except VRP 5W-30 started at 20,000 and changed at 24,500, 25,000, 30,000, 35,000 and now sits at 36k...

Thanks! ESP doing well despite the 4.5% dilution. I haven’t seen dilution in my two 2.7’s go above 3.4% yet even during Alaska winter. That 3.4% was on a 500 mile sample in from Wildtrak in February from Polaris/Analyzers. I do have some bad news about the HPL oil I was trying based off...

I thought about you when this video came out! Considering that LSJ formulated the Driven oil it says a lot when he concedes that PUP gives better results in his Porsche. PUP 0W-40 is looking pretty strong considering it probably costs half as much as the Driven. Even so, I think the...

No, it seems the bottles are almost identical. They both use an opaque kind of plastic which I think stand up to heat better than the clear ones. Horizon (associated with Oil Analyzers) has an article about it which I attached. I think they both use HDPE material. I asked Lake about his...

Valvoline Restore and Protect 5W-30 5,000 mile interval on Wife's 2.7L OBX non-sasq from 30,000-35,000 miles. Seems like I’m getting a little less wear with this than the prior M1 AFE or the HPL in the other Bronco. Probably going to stick with Oil Analyzers for a bit from here on out...

It does reduce bugs and redirects rocks to the upper half of the windshield but you will still get chips and bugs. It redirects wind onto the accessory attachment covers above the windshield so you might need to secure them with some kind of tape to prevent rattling. I mostly use the deflector...

From your manual: So yes, I would say that 91 octane or higher is ideal. I used 94 on a recent trip through Canada while the best I get in Alaska is 90. There was a noticeable difference on hard acceleration - the engine responded more quickly when full accelerator pedal pressure was...

Yeah, I do like how the HPL stands up to the fuel dilution but the 2 ppm Iron/1k mi is pretty typical. I just think you might’ve found some magic with the PUP 0W-40. @crenca What is the total odometer mileage on your Bronco? I think it’s cool how between CarbonSteel running the ESP, you with...

Here is the latest report from my Wildtrak at 25,000 miles after its 2nd 5000 mile run on the HPL P+ PCEO 0W-30. Should have my second VRP report from my Outer Banks by Friday.
