Fully agree. While I do hope selfishly that the gains ahold up, it still feels a little too good to be true. That said, if you wear isn't too bad when you check this summer, I am game to try for the inexpensive change. Anything to take heat out of the overall system.

I bought my oil, ... and got stumped by the gasket. I'm under the impression the gasket is 18 mm I.D and 25 mm O.D.
None of O'Reilly, NAPA or AutoZone carried anything over 14 mm I.D

Advice ?

AutoZone and NAPA were no help; O'reilly had a Dorman part that was 18 mm but the outside diameter looked to narrow to my eye.

Advice ?
The list price is ~ $5 a washer.

The son and I drained, flushed and refilled the reduction gear oil today while the front cap is removed on our 2016 Leaf SL with 37K miles. We hope to get it and the complete and mint 2015 SV parts car to the body shop soon.

We drained out the black ATF and cleaned the two lower magnetic plugs and flushed several times using a quart Marvel Mystery Oil until black ATF stop coming out then dumped in a full quart of MMO draining the same quart two more times. Then we added some new Valvoline full synthetic ATF to flush out the remaining trapped MMO and replaced the low point drain plug and added a quart of new ATF then added 6 oz of Archoil AR9100 fluid and continued to add through the top filler plug opening until it started flowing out the middle plug hole then tighten all plugs. It was raining by then so we just closed shop door and called it a day.

you went all out clearing out the old fluid there Gale!

for what its worth, i have reused the stock gasket washer on the drain/fill plugs twice so far, no issues. If you dont have a new washer handy, probably not a problem.

At the same time, on my wife's Audi, i reused the oil drain washer and it leaked this time, after 5 or so oil changes - so there is a limit :lol:

Yes a bit anal I would say. :)

I have been changing fluids for 60 years and have never replaced a plug washer so far and had no leaks so I need to keep my eye on this job. The washers on our Leaf were not crush washers but just aluminum flat washers.

GaleHawkins, how did the magnets look?

.....added a quart of new ATF then added 6 oz of Archoil AR9100 fluid
Archoil says to use 1.8 oz of Archoil in that much engine oil. Could be they've seen foaming with using over 3 times as much like you did. In high-RPM spinning gears, foaming can be an issue. For example, pro racers don't dare deviate from a fully formulated & tested ("track record" is everything with pit crews) oil, engine or gearbox, out of concern they spark foaming (aeration) at high speed.

Tempting to experiment with different stuff in the fluid though. You just don't know what the final result will be, as it must compete with the regular ATF fluid for surface action. I got crazy a few years back & put in some polymer esters into a differential once, just a bit. I only imagined it might make a difference, who knows?

After a year, maybe check the magnets for iron as the only real measure we have of how much Archoil or anything else might work. Even that is subject to many variables, although one use on here (was it Estomax?) had clean magnets after a few thou miles using premium Redline D6 fluid. Some evidence the premium sauce makes a difference anyway!

I think the technicality is that the crush washer is to help prevent leaks and the flat washer is to help the bolt to stay tightened evenly. Even if they are technically the same looking.

Not sure why a distinction is being made. As far as I can tell, the Aluminum washers are crush washers. It's a soft material and at 2mm thick there's a lot of "squish". Not as thick afterwards so looking at a used washer, one might think "just a thin Aluminum washer"? Aluminum is subject to work-hardening and so there's a limit to how many times it can undergo plastic deformation. I have re-used crush washers in the past due to expediency and not suffered for it, but I do prefer to use new ones if possible. There's a reason crush washers are specified, and re-using them is defeating the purpose.
I noticed you're still working with polymers.
