Yikes, last tank yielded 13.62 mpg. Usually around 17 in suburban driving mix. Poll? Or not...
I added a bottle of Techron this time as I'll be going in for my 20K service after this next tank. I noticed that the container doesn't warn about how many times you can use the stuff anymore - it says something to the effect of use it twice for even better results, and use it every 3,000 miles too.
