Can you elaborate on what the additive issue was with Mobil AV-1? I might not understand your answer but I’m just curious. It seems a shame that oil for small airplanes evolved this way.

I don’t think there is a group iii, it’s really just Phillips and Aeroshell on the market. A Phillips rep stated a few years ago that they would never use a “synthetic”. I don’t think Aeroshell has changed their formulations much since the 90’s, and that was before group iii was very widely...

Piston aviation engines by and large still require leaded fuel. This allegedly poses a problem for certain synthetic oils, for instance, Mobil AV-1 which was, as was, as I understand it, a mostly PAO/group iv base oil formulation. Reputedly, the oil could not adequately suspend the lead salts...

I would just email Dave at HPL and ask him what he recommends for your vehicle/engine/driving conditions and or any specific concerns you have with the vehicle. For me he recommended the premium plus 0W-30 due to climate. They might not answer if too busy, but worth a shot.

fairing, fiberglass?

Second change/third run with HPL Premium Plus PCEO, 5000 miles exactly. 6th change for this Bronco at 20,000 miles now. Samlple sent to Polaris. Sticking with the Fram Synthetic Endurance cartridge filter for now. Also did a triple transmission fluid drain & fill this interval.

How’re you guys getting to the conclusion of a malicious/hostile actor from “position of the fuel control switches”? Shutting down the wrong engine during an engine failure in a multi engine aircraft is all too common, and the fuel control switches are generally how the crew would do that...

I’ve run Fram endurance cartridges for as long as 7000 mile intervals and even with no heat assisted -30F startups have never seen a filter looks like that, with 5W-30 or 0W-30 in the Ford 2.7. It has been awhile but I don’t remember the OEM Motorcraft from the first oil changes looking...

You can pull the thrust levers to idle by hand in most Boeings even with the autothrottle on. The autothrottle will fight you in certain modes, and try to advance, but it’s much weaker than a human arm and can easily be overridden even if you don’t turn it off. It doesn’t matter how slow or...

The PF where I work puts their hands on the thrust levers after the “gear up” call is made. We’ve had MD-11 autothrottles initiate uncommanded thrust reductions (to idle) at low altitude. After those incidents putting a hand on the thrust after gear up is called was mandated airline wide even...

Planning 22 quarts of Premium Plus PCEO 0W-30! Should last me a year in the Bronco and generator!

Thanks, I asked hoping you’d respond! I’ve actually had that problem with my shc-100 grease gun, it won’t flow into the zerks very well, for refill between cleaning/repacking intervals. Could be a dirty zerk too, and I’ve had some success hearing the zerks with a heat gun. But if SHC-100...

Yeah it all has to be taken apart and cleaned annually, with parts washed in solvent and blown/wiped off so the mixing shouldn’t be an issue. Wanting to know what’s best to repack the tailwheel bearings with, specifically, given the disagreement in the manuals. The mechanics I’ve talked to...

I have an experimental Super Cub type airplane that uses grease for main wheel & tailwheel bearings, stabilizer tubes/jackscrew, and tailwheel steering swivel bearing. The maintenance manual specifies Mobilgrease 28 for all of these parts. However, the tailwheel parts manufacturer specifies...

Well stated. Not to mention being held hostage in Chinese quarantine facilities whenever the geopolitical apple cart gets overturned ala 2020. The availability of “overtime”, which is usually needed to get into those 400k+ numbers for most legacy airline captains is highly cyclical as well...

I found it interesting that the manufacturer of a new unleaded fuel for piston airplane engines was using blackstone anlaysis to assess the relative suitability of their fuel compared to the legacy leaded fuels. Granted they had to use engine teardowns and physically measure parts wear to gain...

EMB-145 for 7 years.

Thanks for following up on that. I would also like to know why SD fuel dilution numbers are only 30-50% as high vs OA/Polaris UOA’s when both labs use gas chromatography (~1% vs ~3%). I’ve only sent 2 UOA’s to both labs so far though. I’m planning to send my next few UOA samples to SD, OA...

ERAU is fine for many and I have a BS in Aeronautics from them, but I earned it through their worldwide/extended campus system which has branches at many military bases as well as online options. I completed it while I was working as a regional pilot many years ago. You can save a lot of money...

https://www.airlinepilotcentral.com/airlines/regional It’s all more or less public record. Take the hourly rate and mulitply x 1000 and you will usually be within +/- 20% of every pilot’s annual gross. Usually holds true for regionals but majors are more complicated.
