Rear fog lights. That’s what they’re there for. Heavy rain, dense fog, any reduced visibility situations. Weak little 4W indicator bulbs or LEDs aren’t going to do anything in poor visibility. High wattage fog light bulbs and LEDs with fresnel lenses have been designed to do this for decades. I’ve had them on every…

I’m in full agreement with the other posters. Driving down the highway in bad rain and surrounded by distracting yellow Christmas tree lights sounds like a great way to cause more accidents. At least the crashed cars will already have their blinkers on though?!

The only time it’s alright to use flashers at highway speeds is if you’re taking somebody to the ER / if they’re giving birth. Turning on the 4-ways for rain is beyond ridiculous, but this is DeSantis we’re talking about here, so color me shocked.

Unless your shit’s fucked up, keep the flashers off.

Turn your lights on though. I can’t tell you how many times I see people driving in the fog or other inclement weather, no lights on.  Partial blame goes to automatically backlit gauge clusters.  My car has no backlight unless the lights are on.

This is a dumb idea.

Ram Hemi “recommends” it.

Look the simple story here is that octane rating is a means to prevent pre-ignition. Any car with OBDII will tell you if you are doing it wrong because it will have knock sensors to detect pre-ignition. The best tuning you can hope for is as much timing advance as you can get before pre-ignition. Thats the point of…

Umm no. My ‘99 Suburban 2500 also has the 7.4l and it will NOT run good on ethanol. And the only way to get E0 in these parts is to buy premium. If I travel out of state (to places where there is no E0) I always end up with an excessive lean condition and a check engine light. SO 93 octane is what I buy. I also need…

There should be a whole article on those who use mid-grade (89 octane). Literally nobody uses that. We need to understand these people.

Even the article image shows that button new and shiny.

Can you camp out at a gas station, and interview the first person who uses 89 octane?

Octane is simply a rating measuring resistance to detonation. A higher compression, higher revving engine is usually going to be designed for a 91 (or 93, if you can get it) octane premium fuel. If you add 87 to the tank, as the revs climb, you’ll notice that the engine is cutting timing, because a modern ECU will…

So, I’ve actually tried this experiment on someone else’s dime, so that was cool...

Definitely do not put premium in the suburban. The vortec 7400 will make no use of it and it is throwing money away. Even with a 7 psi centrifugal supercharger on ours we would run 89 in the winter because it just didn’t need it. No pinging. In summer or under load it was 91 minimum for sure but again... Supercharger.…

European octane is measured differently and not directly comparable to US octane rating.

If your engine is naturally aspirated and not high compression, running anything other than the recommended 87 is throwing money away. It’s that simple.

Sorry Liz, but Chris is wrong. Engines are designed to run on the recommended octane rating, no more no less. Getting premium gas when the engine doesn’t call for it is simply a waste of money and yields little, if any, benefits.

PA’s is bad because of our freeze-thaw cycle plus the fact that just about every truck that’s servicing the heavily populated Northeast uses I 80, 81, 83, 78 and 76 through the state.

PA has two seasons. Winter and Road Construction. But with half the year devoted to roadwork, nothing ever gets repaired.

You can actually play that game going between different counties here. If you’re really good at it you can guess the population, median income and largest industry within the county. It’s amazing how forgotten the “Pennslytucky/Pennslyabama” roadways are, so much so you can physically feel yourself enter them with…

You can always find the state line between Pennsylvania and Delaware because the road goes full Baghdad once you exit Delaware.

“We are the richest country on earth”

WRONG

We are the country with the richest people. “Typical Americans” have been steadily falling behind the rest of the first world for four decades now.

That’s the whole “wealth inequality” thing. Oligarchy. Rigged system. Unregulated campaign finance.
