Pass a class 1 medical would be your first step. Search for aviation medical examiners in your area. You can use local flight schools or big academies. They each have their pros and cons. Generally you will spend about $75,000 dollars to go from 0 flight time to a flight instructor with 250...

The question has been asked many times and the general consensus seems to be there is no such oil, but you can use a thick-for-grade euro oil or step up one SAE viscosity grade to compensate to some degree for the thinning effect the fuel will have when mixed into the oil. What that doesn't do...

About 20 psi of boost max, I don’t think I’ve ever seen mine over 18. Aggressive highway merge etc it will get into the mid teens pretty fast. It doesn’t need boost to cruise at 70 mph or less unless you’re going uphill, at least in Bronco. Most city driving you can stay out of the boost...

2.7L Ecoboost Tear down and Wet belt oil pump discussion Even though the video indicates some wear in that engine’s belt, I haven't heard of a 2.7L failing from the wet belt drive oil pump and they've been using that design since 2018. AI says Ford has manufactured almost 1,000,000 2.7L...

I got schooled hard on here when I claimed my 2.7 was shearing oil too. They do dilute the oil with fuel in the 2-4% ballpark, so that probably played a role in about half of your viscosity drop. I think most 10 cSt ILSAC oils will drop about half a cSt in service even with no dilution, but...

Just compare the differences in results from a few different labs with the same sample to see the futility of small sample size UOA. On my last sample there was a full order of magnitude difference in the LSJ “were metal per 1000 miles” metric between wearcheck, which reported 0.5 ppm/1k and...

The 0W-30 seems to be preferred, there are a lot of threads on here comparing the 5W-30 to the 0W-30 ESP. The forumlation of the 5W has changed over time. The stated reasons that 0W is preferred are usually that it has Esters and more PAO base oil compared to the present 5W formulation. I...

I got a chance to retract flaps instead of gear at pos rate in a level D Boeing wide body sim yesterday. Not a 787, but fwiw the error didn’t really matter that much. We used the same runway and weather as the accident. Even at structural max t/o weight, the jet pretty much out-accelerated...

You should probably look into the stribek curve. Too thin or too thick can both increase friction and heat. There is a Goldilocks zone for the lubricant viscosity and it is different for different engines. Here is a video about it:

The Ford 2.7L ecoboost engine pretty reliably dilutes the oil with fuel at 2%-5% on Polaris Labs UOA but Blackstone doesn’t use an accurate test for this. For the oil viscosity to drop as it did in the OP’s UOAs (Amsoil says it starts at 11.3) it’s probably about half from fuel dilution and...

Stupid question but my airplane’s filter mounts with the open end down and the filter adapters can be fragile, what’s the best way to make the hole in the dome while minimizing any chance of damaging the filter mount’s threads or structure? Drill? Hammer and Nail? Hammer and Punch?

This isn't the 10W-40 but it's a UOA of the Kohler brand 5W-30; it was drained out of a 2013 38RCL which has a GM Vortec V6 engine. Maybe it can give you some idea of part of the additive package in the 10W-40 as well, but that's just a guess. This was only run for 8 months and about 16 hours...

The plumber said slope and flow were OK, both the first guy that came to clear the clog and the resin coating company said that. They measured slope with their borescope tool somehow and had me run a bunch of water from the shower to check the flow. They said the pipe did shallow out a bit...

Got a slightly concerning Oil Analysis today. Another 24 hour interval; I had to lap the #1 cylinder exhaust valve at about 21 hours into the interval because compression/leak down was 40/80. The lapping worked to bring it back to 77/80 and was still holding 2.5 hours later at the oil change...

On the low-flow & flushing discussions: the clog is happening about 60 ft away from the problem toilet. It’s happening about 3 feet upstream of a 45 degree joint where the guest bathroom and garage drain join the main line for the rest of the house. Plumber said slope and flow was good once...

I don’t think those fuel dilution numbers are abnormal for an ecoboost. I wouldn’t go on any maintenance/repair expeditions based on your UOAs. I’ve been looking more at 2.7L UOAs but 2-4% is common in Polaris/OA ecoboost analyses. My two 2.7’s are usually about 2% in summer and 3% in winter...

Speediagnostix does particle count on a UOA for a $40 upcharge. I’m not sure if that’s the same service as what you’re looking for when you say particle analysis.

We don’t buy those and no one in the household says they’ve ever flushed anything but this TP and #1/#2 down the toilet. I think it’s a Costco brand TP but this is the last roll so I don’t have the packaging any longer.

I’m not sure, but the resin coatings company said I would probably be looking at $60k to remove and replace the old pipes. While I’m not saying they did, I realize that they have an incentive to over estimate that quote though.

I purchased my first house 5 months ago. Built in 1999. There is a first floor garage with an epoxy floor and a drain with a p-trap. So far 3x I’ve come downstairs to a 7-10 ft diameter puddle of sewage in the midddle of the floor. There is one guest bathroom upstream of this drain and that...
