I hear you on the 7.3. Great reliable engine. Loved mine on a manual transmission! I put 100k on that truck and sold it for 1,000 less than I paid for it.

Loved my tuned 6.4 with a H&S 300hp tune on it. Was awesome!!

Am enjoying my current 6.7 and put an order in for a 2023 last month when the order banks opened. Their high output 6.7 now puts out 1,200 ft/lbs - that's unreal. Praying we don't have a diesel shortage!!

Fuel delivered to stations at a rack price, station operator adds the state/local tax and then their margin = price at the pump. FL had a 25 cent state road tax that was suspended in October due to the hurricane so prices dropped Oct 1-31 by 25 cents. Obviously if a station is at a busy intersection or an expensive town their price will be higher than if its got lots of competition.

Costco fuel is about 45 cents a gallon lower than local station average. The stations on the same block as Costco are about 30 cents a gallon higher Now clearly Costco is running high volume vs. lower margin to get people to come to their stores. In season, my local Costco sells 60,000+ gallons a day. They get a dozen tankers per day to keep them full. 24 pumps/ 8 lines of three each and unless you go early they always have a line. My personal pet peeve: Old lady buying 4-5 gallons of fuel.........WTF you saved $2 but drove here to do it. If you have a truck/suv and get 25 gallons, then you save $9 every time you fill. I can't make it worthwhile unless I'm down there for something else anyway.....if you burn 1-2 gallons getting gas then you really didn't save anything. (drive 15 miles each way for example)
