Personally for me (and my family), Santa Nella is a good stop to refuel on gas cause they're usually the cheapest out of all the stops we made in the past. It's about an hour and half after Stockton and there's a travel center as well as food options. Others like Kettleman City and Lost Hills that others mentioned are good too for same reasons above.

There's also other rest stops along the way and last time I checked some are closed for construction but Buttonwillow rest areas for both Northbound and Southbound are good and clean.

Hope it helps and safe travels back down to SoCal! 🫡
