Much bigger.
Category: Automotivity
I decided to do a little math now that I’m at 1700 miles in the Golf. My average mpg in the Golf so far is 38.9mpg. The TT average is 23.2mpg. So, in the 1700 miles I have on the Golf, I have used 43.7 gallons of diesel … and, now that I’m using B5 (95% diesel, 5% bio-diesel), it’s really only 41.5 gallons of fossil fuels. for that same 1700 miles, the TT would have burned 73.3 gallons of premium unleaded. So far I’ve saved 31.8 gallons of dino-juice. Not only that, but the diesel tends to run about $0.10 per gallon less than premium unleaded, so I’ve probably saved about $85. That doesn’t sound like a lot per mile ($0.05), but it should add up. It’s nearly 1/3 of my car payment, and about $1000 per year.
My second tank was 39.4. I probably had a little more highway use with this tank. It also helped that I got 43.8 mpg (indicated … it seems to read low) one morning on the way to work by sneaking in behind a truck on 114.
So, my “lifetime” average is up to 38.5 now.
I’m trying out the B5 from Green Spot Market for this tank. It’s pretty convenient, just the other side of the lake.
37.7 mpg isn’t too bad for my first tank. I need to tweak a few habits I think, to bring that up a bit. I need to find a spot to put the smaller version of these over in the sidebar…
So the Golf gets 62.5% more miles per gallon of fuel than the TT. Plus the fuel is cheaper (diesel is running about equivalent to mid-grade gasoline & the TT takes premium).
Not bad for my first real morning commute. I got 42.5mpg this morning (according to the car’s computer). And I wasn’t even really trying. ![]()
