Gas Prices Rising and Oil Change Costs Also Expected to Take Off

The ongoing military conflict with Iran has put a strain on the world’s oil supply, and in the short term that’s showing up in what Americans pay for gasoline. However, the impact of shortened supply is spreading, and soon vehicle owners are going to feel the pinch even harder.


According to the Independent Lubricant Manufacturers Association (ILMA), a group of its representatives met with the U.S. Department of Energy recently to discuss rising concerns about shortages of base oil supplies.

Base oils are used as lubricants and are categorized in four groups. However, it’s Group III base oils that are preparing to put a bigger crimp on American consumers. Group III base oils are used by automakers to lubricate the insides of car engines in the form of synthetic oil, and they are most affected as the Strait of Hormuz remains closed due to the war with Iran. Sixty percent of Group III base oils are used in automotive applications, i.e. synthetic oils.

Nearly 45 percent of Group III base oils comes from the Persian Gulf, either the tankers unable to use the Strait of Hormuz or from production facilities currently offline in the region. The ILMA points out there are no simple ways to resolve the problem. 

“Compounding the issue, South Korea — responsible for about 30 percent of U.S. Group III imports — relies heavily on crude oil shipments from the Persian Gulf. While Korean refiners may pivot to alternative crude sources, lower yields are expected,” the  group wrote in a recent report.

Exacerbating the issue is that U.S. oil producers aren’t positioned to take up the slack. While they do produce Group III base oil, the additional capacity to make up the shortfall won’t be operational until next year when refineries by Chevron and ExxonMobil come online. These types of oils can be “re-refined” but producers have limited capacity and don’t have the materials or feedstock necessary to produce it.

Few products follow the laws of supply and demand like oil does and supplies are only getting shorter, which means U.S. consumers can not only expect to see the price at the pump rise for the foreseeable future, pulling into the bay to get your oil changed and other automotive lubricants needed to keep a car in working order is going to mean more money out of the pocket of consumers.

General Motors may be first affected as its Dexos oil products rely on Group III base oils, meaning GM product owners may find it hard or expensive — or both — get the right Dexos product for their vehicles. So concerned is the ILMA about this issue, it appealed to GM to allow for “temporary flexibility” for Dexos licensees so they can adjust the blends used to produce Dexos products.

The company offered sympathy, but no flexibility,  saying in a letter to the organization, “We recognize that Group III supply constraints may continue for some time, and we encourage additive companies and oil marketers to submit technically justified alternative group III base oils for evaluation.”

    For all the screaming about gas prices and oil change prices, there is a way to avoid these and still have private transportation. It's called Electric. Yes, many EVs are simply too expensive, but if you're looking for a new or used vehicle to replace your current one, take a look at the EV offerings in your price range. EVs are simply less expensive to operate and maintain, so if the purchase price is comparable and the EV meets your needs, get it. What you shouldn't do is get an EV just to be "green" - that's a guaranteed way to waste your money and be unsatisfied with your vehicle.

    just use motorcycle oil its better than synthetic anyways it still has the zinc additive in it

  • Vid169489471 The technology exists today to produce a variable color temperature (kelvin) LED lamp. It can vary from 2700k that soft orange look to 6500k the bright daylight with the bluish tint.Since everything in a late model car is computer controlled, it would be an easy task to write a few lines of code that enables your vehicle to not only dim down from hi to low beam but to shift color temp down to the 2700k range for oncoming traffic, then back up to 5000k once oncoming traffic has passed. For the operator it would be automatic and seamless. For older cars they could be retrofitted with LEDs that are 2700k on low beam and 5000k on hi beam. As far as standards, there could be a lumens max, and a minimum. Several States already have minimum lumen standards going back to the old incandescent bulbs. Why not update these to national standards.
  • Jam169859557 More regulation is needed for ALL vehicle lighting systems. [list=1][*]The lighting that is most blinding are the rapidly flashing red, blue and amber lights on emergency vehicles. The lights themselves are blinding, flashing so rapidly that it's impossible for even the sharpest eyes to adjust. What's worse, is the nature of the emergency requires a careful view of the area surrounding the emergency vehicle. There is something going on that needs to be seen. More flashing lights is not the solution.[/*][*]Brighter headlights need to be regulated. The tall riding vehicles do not need headlights positioned so high that they blind drivers in lower riding vehicles. And those heasdlights need to be aimed properly. When I first started driving my 2020 Subaru Outback, many drivers would flash their lights, hoping I would dim my lights. This stopped after I performed am easy adjustment that tilted the beam lower. Late model Subaru headlamps are designed with a sharp cutoff that project less glare above the hood line. When the headlights are properly aimed, other drivers are not blinded by the beam.[/*][*]Customized light assemblies make it more difficult to see the marker lights (tail lamps, turn signals and side marker lamps) that have been tinted. There are many municiple codes that prohibit this tinting, but these laws are seldom enforced.[/*][/list=1]Solutions: Tight controls on emergency vehicle lighting. In trying to make these vehicles more visible, a dangerous side effect is reducing the ability of drivers to see the surrounding perils.Headlight design regulations that reduce the height of the headlight assemblies. Just because a pickup truck has a hood that sits 4 feet abouve the pavement, it does not mean the headlights need to be so high. Owneres should maintain proper adjustments to their vehicle headlights.Establish and enforce regulation requiring a illumination standard be followed.
  • Stl170698708 as someone who hates big government, and their interference;but you can add me to the list of people that are blinded by the lights.unfortunately "the poop is out of the horse and no way is it going back in"They have had 5 years to make lights bigger, badder and brighter because in the vehicle work it is go big or go home!Trucks are the worst because so many people use them to express their dominance and that is big, big, big $$ both at the Original Purchase and in the Aftermarket world.If, we are so lucky to get some good government regulation on this it will also take some very good Court enforcement to get the aftermarket people with fines and lawsuits.Much like the EPA did with the Diesel Tuner Industry that felt emission regulations didn't apply to them.This is from someone that owns said pickup truck with the same bright headlights,but i only use the truck when I have too and always turn off the Fog lights when driving in traffic.
  • Art65765977 I saw a porsche 911 with the most amazing headlights from behind approaching the Sunshine skyway in Florida. The pattern was 108 degrees across sweeping the road like a broom. My brother and I were amazed. I don't know what it looked like from the front but i am sure it was better than American cars
