Sometimes Walter just plain surprises. We are always hearing fuel economy here and there, and by now you know that we don't pay too much attention to fuel economy unless it really gets obscene. Literally using too much gas or a small engine using too much gas for its displacement.
We also subscribe to "You need gas to make horsepower".
Here is Walter with its V8 doing 9.1 liters per 100 kilometers on the highway. With a brew of Petro Canada 94 and Shell Premium with Nitro.
Here is the deal with Walter and gas:
Walter will run on regular have tried it a few times just for the fun of it. Although Walter sends distinct messages that regular is not part of its preferred menu.
On this road trip Walter just loved the brew of 94 and Nitro.
If gas is a commodity, and premium gas is possibly all the same. Walter has a preference for Shell Premium now with Nitro, or Petro Canada Premium or 94 (not available at all stations).
We were surpirsed at the 9.1 economy, expecting to see 9.8 / 9.7....
Yes a Benz with a V8 remains a superior highway cruiser, if you have never experienced a Benz with a V8 on the highway its a genuine joy. Although Walter is geared to ideally cruise slightly faster than what is an acceptable speed on our highways.
The difference with an old school V8 and a 5 speed, the car is geared to cruise in the 2,400 to 2,600 RPM range and will simply power up without shifting gears. Newer vehicles with an 8 speed automatic will cruise at comparable speeds doing <2,000 RPM and usually downshift at least 1 if not 2 gears to power up.
There is a "cachet" about an old school car that just powers up...
