Oil and fuel prices remained volatile, rebounding in Wednesday overnight trading after recent lows (six‑week closing lows for ULSD and gasoline; seven‑day low for crude). Prices climbed in the overnight trading after US strikes on Iranian targets following the helicopter that was shot down.

Crude is at $89.70
RBOB is at $3.0461
HO is at $3.6048

The markets have been climbing due to escalated issues in the middle east. Market forecasts show crude, gas and diesel going down over the fall-winter months. I say this to warn people of stocking up on products via worrying about supply shortages. Shortages are occurring due to shipping and logistics, but not because of unavailable crude. If we can figure out the global shipping and logistics issues that these wars are creating, we should see pricing decrease once refinery utilization and finished products catch up.

Crude is up at $91.54
RBOB is up at $3.0959
HO is up at $3.6539

Oil supply and pricing: The markets are rising and it doesn’t matter what flag a supplier is flying. All majors and regional blenders are facing the same issues. Supply of crude is not getting to the refineries as well as an extreme shortage in additives to blend with those refined crude products. I have thoroughly enjoyed our partnership with Chevron, as they are the only major that has its own crude stock, refineries and additive company. During Covid, this was crucial as it kept us better supplied than others. I expect that to be the same case during this extreme time period. I have seen multiple letters from suppliers saying this is worse than the issues faced during Covid.

MG Oil makes a strong commitment with regards to carrying inventory. We have over 225k gallons of bulk inventory storage within our two warehouses in Rapid City and Gillette. We do our best to keep them on the top side as supply is also crucial. This does not include all of our packaged inventory. We are here to help you stay running. Please reach out for any information you may be seeking.

Markets are going to continue to climb and supply is going to continue to weaken. I strongly encourage you to change oil based on analysis versus minimal time intervals, whether that be miles or hours. These current oils are not the oils of the past. The base stock and the additive packages are designed to go further. Reach out to us for more information.

We appreciate all of you and are grateful for your partnership.

The markets are up thanks to escalating actions in the middle east. For simplicity, any positive negotiations that hit the news, it will send the market down, and any negative news or escalation amongst the wars going on will send the market up. From an actual supply and demand conversation, their is plenty of supply, just not plenty of routes to get the supply where it needs to go. This is causing a shortage in finished products, as the crude is not getting to the right locations to be refined. Prices continue to soar, it will likely have a downward impact on demand. That being said, we are headed into our higher demand times with travel, harvest, etc.

Crude is up at $96.20
RBOB is up at $3.1802
HO is up at $3.8332

Markets climbed higher Sunday night and into this morning on new developments of fighting between Russia and Ukraine, Israel and Lebanon as well as the US and Iran. The market pricing fluctuation continues on the optimism and pessimism of the news surrounding the oil supply and supply channels. We are hitting a time where we are starting to see shortages in finished l***s, especially those needing group 3 base stocks. Russia just put a ban on shipping Jet fuel, which will start to impact that market.

Crude is up at $90.01
RBOB is up at $3.0902
HO is up at $3.5886

The markets dipped down most of yesterday and the barrel of crude was around $88, but the markets have rebounded slightly this morning on increased instability of the supposed truce between the US and Iran. We took down some drones, and they attacked a military base. This created a slow down/halt of shipping traffic through the strait of Hormuz. Both countries appear to be measuring each other up, and that will move the markets up.

Crude is at $91.18
HO is at $3.6498
RBOB is at $3.1902

05/26/2026

We have more news surrounding the closure of the Strait of Hormuz, along with the US military actions that have been taken. Negotiations are still being had, and hopefully we will see some form of resolution in the near-term.

Crude is at $92.90
HO is at $3.7997
RBOB is at $3.3091

These prices were as of this morning.

Mathematical equation and scientific reasoning for saving money when it comes to gas. Charles's and Gay-Lussac's laws of gas expansion states at 32 degrees F the expansion rate is 1/491.67 for every 1 degree F increase in temperature. I'm not a math guy, but, if you fill up at 6am and the temperature is 32 degrees F, and you park your car and drive it at 2pm, when it is 82 degrees F (change of 50 degrees) you will have increased that 20 gallons of gas in your car by a little over 10% or 2 gallons.

Do I have any math wizards that follow us to verify my calculations?
((1/491.67) x 50) x 20 (gallons of gas purchased at 6 am) = 2.034 gallon increase. 1/491.67 is gas expansion. 50 is the degree change in F. 20 is the gallon of gas purchased hypothetically.
