OK. I think that should be enough ideas to start out.
I will start experimenting once weather turns a bit better and report the results.

I guess the logical thing to do then, would be to only fill her up half, and save another few 10s of lbs of weight. Which is what I used to do with my 2006 Fabia TDI. The weight gain can only improve your mileage, provided that you don't put in extra miles to drive towards your fuel station of choice. It won't be much, maybe half an MPG at most, but all little bits help.
Plus, of course, your shorter tank intervals should give you more tangible driving techniques vs. MPG results.
I don't consider having to tank more than once a month unreasonably frequent. Do you?

No I don't

Measuring MPG is easier tank to tank though as it gives you a standard point to measure against, and I have a choice (depending on price via the web) on where to fill up of about 2-3 garages under 3 miles from home.

Filling up the exact same amount of fuel every time may be an equally good, if not better point of reference, imho. Say 20 liters (or equivalent amount of gallons, or whichever unit Scottisch stations apply) to the drop at every top-up, in stead of now 41 liters, then 42, then again 41.5, presuming your Fabia has the same 45 liter tank mine had.

That method is only valid if you are running to empty between fillups since you don't know how many of the 20L you put in last time you actually used. Fuel sending units are not accurate enough to base it on needle position.

Still not sure how this works. We use litres here and my car is ventectomied so I can get more than the official 41 litres in. The needle just reads E, 1/2, F with quarters not actual capacity.

It doesn't work, unless you plan to run it til empty before filling up.

I only P&G in 5th gear. Down hills(overpasses here) and on flat roads. My trip to work is almost 60min through town 25mph and 50mph areas. I usually pulse to 5mph-10mph over and let glide to 5mph under. The Beetle is smooth to shift so i don't even use the clutch. 1st tank I tried this I was hoping to get 50mpg, I got 58mpg!!! WOW! I do not shut the motor off while gliding but I did shut it off at long lights. Seems to be mixed reviews about if this saves fuel or not.

Turning off the engine will save a small amount of fuel, but IMHO doesn't justify the increased steering effort and wear associated with restarting.

UFO, I only shut down the motor at long lights, or coasting up to a long light. No turning required. IMO the Beetle is a excellent Pulse and Glide car. The shifting is almost effortless in and out of 5th gear with slight throttle pressure. With my Passat the tranny is a little more sloppy so it makes shifting in and out of 5th gear harder to do without using the clutch.
