Good observation: that’s how it’s supposed to work. Premium fuel has additives to delay the ignition as it’s mean to be used in an engine that sucks in more air to be mixed with the fuel and compressed at a higher rate.

Profits are made in the margins for volume sales.

That has got to be a seat of the pants estimation. I wouldn’t think 10F temperature difference would play that big of a role, considering that elevation and humidity are also going to be factors taken into account that play an equal role.

Timing shouldn’t be an issue with EFI. But yes, run premium because it means the engine is made to take advantage of the higher compression, producing more energy, and in effect: using less fuel and increasing mileage.

I’ve found non-name-brand fuels can be better for an engine because many of those gas stations will contract out with a company that purchases fuel from older refineries. This is especially important for diesel engine owners (I have a VW TDI) because biodiesel mixes - particularly from name-brand companies - has a…

Your mechanic is wrong. All fuels have additives these days. The higher octane actually has more junk in it to retard the fuel explosion so it can be compressed more. Ideally, with a gasoline engine, a higher compression ratio includes more air mixed in, which allows more energy to be generated. On some cars, the…

I mean, how exactly does one fill their car with gas if someone isn’t around to do it for them?

On a drive back from Marfa, Texas a few years back, I was somewhere in the region along the border with Mexico, in places where I didn’t see anyone for hours. There were a few deer standing right in the middle of the road, watching me drive by. Then I started seeing convoys of pickup trucks, big ones, hauling workers…

Had to double check this wasn’t a sneaky Wes Siler piece about his uber off-road Subaru.

That’s an inherent problem with displays; they are a flat plane that is in constant focus, so we have to strain our eyes to read the information when shifting from a nearby flat plane to an object at distance. That’s even more problematic when dealing with high speed decision making on the go. I know companies have…

I’m doing my dissertation research around augmented reality and building training systems with it. With these kinds of applications, the problem isn’t necessarily in the ability to project and overlay images, but in gathering and processing quality data.

“Fix things” ... as in adding an entire volume of medical diagnosis related to iPhone injuries.

Frankly, I absolutely and 100 percent applaud the move by U Chicago.

No dude, listen, this isn’t an unreasonable fear. It’s not that people aren’t checking their mirrors, it’s that (1) people don’t drive in a straight line so you can’t see straight backwards where someone is coming from, (2) riders break the speed rule all the time and will come up a lot faster than expected, or (3)…

I’m mixed about lane splitting. I’m in the Chicago area and would like the *option* of lane splitting like how it works in California, but this is a lower priority given all of the other absolutely terrifying shit Chicago drivers do, and the utter lack of any law enforcement on the interstate to enforce the rules of…

I understand, but I just do not see a correlation between gender and a diagnosis outside of the realm of gender-specific diagnosis. What you’re essentially arguing is that women are better diagnosticians, and that’s ridiculous.

What you’re more likely encountering is the conservative nature of many medical schools and…

That prednisone can be nasty stuff. My SO is in the other room with a puffed up face covered in acne and a migraine from coming off of having her system blasted with 120mg of prednisone. That’s on top of a 102F fever due to a UTI that came about because the prednisone dropped her antigen levels too low. The long term…

Luckily my fiance is still on her mother’s insurance plan, which is top of the line. She has lupus and a kidney transplant, but her insurance allows her to have private physical therapy, massage therapy, and a physical trainer. The insurance carrier, Blue Cross/Blue Shield of Minnesota, encourages her to see these…

I don’t think that’s fair and I have zero respect for your sexist comment.

The pain management team that was able to help my fiance get through her post-surgical transplant recovery — after having built a tolerance from taking opioids for lupus — was an all-male team.

After complaining endlessly to her all-female…
