Well, I'm saying good pulse and glide taking advantage of your Max's built-in fuel cut out will be almost as good. Big long EOC's like you mention will save you alot of gas, than just lifting off as part of P&G.

I find it really hard to squeeze the last bit of economy out of a nissan V6, it's the price you pay for having the ability to embarass bigger more expensive cars. I've got to work on some aero mods.

Hot tip: I think max's are one car that exhaust mods help economy - theres a nasty restrictive bend in the y-pipe. Known for 10%-15% power right there, and some say a little MPG - as long as rest of exhaust is standard.

Anyway here's the official information from Nissan on the transaxle issue:

FLAT TOWING OF NISSAN VEHICLES
This bulletin amends NTB99-020b. This version includes additional Model and Model Year application.
Please discard all paper copies of the earlier bulletin.
APPLIED VEHICLES:
All Models
1992-2004
SERVICE INFORMATION
This Bulletin contains guidelines for towing Nissan vehicles with all four wheels on the
ground (sometimes called "flat towing"). Customers sometimes use this method when
towing the vehicle behind a recreational vehicle, such as a motor home.
• Failure to follow the guidelines in this bulletin can result in severe transmission/transaxle
Automatic Transmission/Transaxle Vehicles
MODEL
MPH/DISTANCE
All Nissan
Flat Towing will damage internal transmission parts.
(Including
(see notes below)
Murano CVT)
• DO NOT tow any automatic transmission/transaxle Nissan vehicle with all four
wheels on the ground (flat towing). Doing so WILL DAMAGE internal
transmission/transaxle parts due to lack of lubrication (the
transmission/transaxle oil pump only operates while the engine is running).
• For "emergency towing" procedures refer to the limited MPH / distance
procedures as outlined in the vehicle’s Owners Manual.
• Never flat tow a manual transmission/transaxle Nissan vehicle backwards, but
To tow a vehicle equipped with an automatic transmission/transaxle, an appropriate vehicle
dolly MUST be placed under the towed vehicle’s drive wheels. Always follow the dolly
manufacturer’s recommendations when using their product.
Manual Transmission/Transaxle Vehicle Towing Guidelines
MODEL
MPH/DISTANCE
All Nissan
60 mph / 500 miles (see notes below)
Always tow with the manual transmission/transaxle in Neutral.
On 4WD vehicles, place the transfer case in the 2 HI range
(failure to do so will cause the powertrain to bind up).
After towing 500 miles, start and idle the engine with the transmission/transaxle in
Neutral for two minutes. Failure to idle the engine after every 500 miles of towing may
cause damage to the transmission/transaxle internal parts"
Yikes. Engine on or nothing in the case of the Auto.
