now runs the Bradford refinery and they sold the Kendall name to Conoco-Phillips, I believe. Sorry, I guess that really doesn't answer the question, but it might help you track down the answer.
Sheetz Inc. is a family owned convienience store chain based out of Altoona, PA. They have several stores in Pennsylvania and a few other states.I saw the Security Pennsylvania Grade in a store which also sells Brad Penn.
Sheetz is actually a GREAT convenience store. They all have a little restaurant inside with reasonably priced fast food, and I think they're all 24/7.
Nice, clean, well-lit.. they make me happy.
Their motor oil prices are a little steep, but not worse than most places.
The last time I stopped at one it had Pennzoil at a little over $3/qt, and store-brands at SAE HD 30, 5W30, 10W30 and 10W40. Also a house-brand Dexron III/Mercon ATF.
