The only thing I could say would be full moving from the fuel pickup causing it to starve - but it'd be a different feeling - more of a fall on it's face type of feeling rather than slowness.
I'd actually think you'd experience the opposite as there is less weight in the vehicle making it easier to move. |

Maybe the way the tank pressurizes affects the ease at which the fuel pump can draw the fuel.
I am with GMTURBO43 - I notice a bit more pep when the tank is near empty, due to less weight. |

Hmm..didn't think of a pressure thing...
Here's an experiment. When the tank gets to half full (or empty) pull off the gas cap and put it back on (make sure it clicks 3 times). See if that makes a difference. |

I've noticed the ride is different with a full tank, but I've always figured it's the additional weight in the back.
Can't say I've noticed and acceleration difference, but considering how deceptive the CVT is to begin with, I wouldn't trust my senses there. I wonder if a GPS has enough resolution to capture the differences... You could accelerate from a known state, and look at the distance/time data points and plot them on a graph. To keep temperature and barometric pressure minimised, you'd have to do the empty tank first then fill it up and do the full one. |

We are still talking "feelings" not facts.
Get something that objectively measure acceleration. G-Tech would do.
I just cannot imagine that heavier car would be more responsive. It goes against physics. But then what do I know..... |

Full or near empty, The Gold Rush is much quicker after she's had a bath.
Probly the molecules are slicker.

How much are they? I guess the problem I have with getting a G-Tech is while they would do the job very well, after I knew, I'd put it on the shelf.
A G-Tech rental for a day, would be good... |

| Are you testing this with the engine and CVT at full operating temp? As you know the CVT is a bit sluggish until it warms up. |

| I find the CVT to be sluggish on a cold start, so I find the car noticeably peppier when its warm. |
