Thanks for the feedback everyone. It (still) seems that we have to eat the bullet on fuel costs while in Canada but may be able to save $$$ in the states with TSD and just using the simple Gas Buddy app for finding better toad gas prices. We've done this trip twice now and generally prepay canadian cash @ the diesel pump but haven't really noticed appreciable savings when doing so.
Thanks for confirming that the Gas Buddy card has a daily limit!I thought it was because I was new to using the card and that the limit would increase with usage. Just hadn't spent the time to call them.What are the discounts like with the TDS program?
Noticed you have a 2009 5.7L hemi GC. Have you hit the lifter issue with that engine?
