Well, David, whether something is a "waist" or not sort of depends on the
circumstances and your point of view, doesn't it?
Some would consider it a waste to spend $6 plus shipping (twice!) on a paper
decal reading OVERDRIVE RELAY that bleeds into illegibility within a few
months.
I change my gearbox oil twice a year because:
It's relatively cheap and easy to do
There is no filter in the gearbox and overdrive to remove more than gross
contaminants
I grind the gears more frequently than I would like, more due to lack of
attention than the type of lubrication
Grinding gears puts metal particles into the oil
Some particles don't settle out or get screened by the mesh
Bearings and small openings don't like metal particles and contaminants in
their oil
Some years I put as much 10K miles on my car
It gives me peace of mind
It has worked successfully for me for the last 25 years
It feels about the right interval to me
If a Redline change is $56 and I did it every two years for a total cost of
$112, a comparable TWICE a year change with 30W during the same time would
cost $40. At the same cost, I could change 30W oil more frequently than
every two months. That was my question: is the performance improvement
with Redline worth the difference in cost?
Do you have data to justify a 20K interval, or is that just your personal
"comfort zone"?
Cheers!

Why would you change the transmission oil twice a year. That is a total
waist. You might need to change the transmission oil every 20,000 miles or
so.
