Maybe it's just that the .liberal talking heads who get their lemmings to complain aren't pointing it out. they did under president Bush, why not under president Obama?
Anything think there is bias?
Yep.
With how much better an engine runs on the higher grade gas, premium is a better buy. Especially if it's only 20 cents more, or less than 20 cents more per gallon.
meh.
My daily driver is a 93 S-10. It's never seen a drop of anything over 87. It has 220,000+ miles on it and you can't even hear the engine at idle.Yes smartass. It runs.
I've owned multiple cars and driven them > 200,000 with zero issues related to fuel composition.
It does, but the tradeoff is loss of power (which is part of the reason you're buying a powerful car to begin with) and gumming up other engine parts.
The reason a no knock sensor is there is so you don't flat out destroy your engine by using low octane. It doesn't necessarily do away with the progressive damage.
English is not his first language.
I'm happy for you. One of my best friends owns and independent mechanic shop and he is probably one of the best diagnostic mechanics in Texas...all the San Antonio dealerships use him as a consultant when they run across a problem they can't identify. He is the one that made me aware of the importance of using decent gas. I'm glad you haven't experienced any problems but he has made millions from the issue.meh.

Hmmm...he's made millions out of an issue. Interesting.
LOL...
Loss of power means lower mileage too. The knock sensor allows the computer to adjust engine performance with the fuel grade. I think we agree with that. Still, the higher grade gas will give you better mileage with such a computerized system, and pay for itself. try it some time. Check your mileage with about three tanks of the gas you use now, then run about three tanks of premium and see the difference.
When gas was around $1.30 a gallon, the 20 cents difference in regular to premium was a ridiculous thing to pay if you didn't need it. That same 20 cents is worth paying with the gas over $3/gallon as it is a much smaller percentage.
Sounds like a very talented businessman.
I'm not a mechanic with a shop. I have been tearing down engines since I was 6 however.
Valero gas specifically was one example. The guys running around buying the cheapest gas they can find end up with a lot of in their gas tanks. Then they go drop a tank of Valero gas in there which has VERY harsh detergents...the crap goes straight to the injectors and next thing you know they just spent $1000+ for new ones.
Like CC says, don't buy the cheapest gas.
When it comes to regular vs. plus vs. premium, the difference is that most newer engines control the power with the knock sensor(s). The higher the octane of gasoline, the greater the energy density. This is what makes the difference. At today's gas prices, this energy density increase is worth the 20 cents more per gallon.
Ummm. no. The energy density is the same across grades.
So these harsh detergents aren't found in the super unleaded at Valero? Only the regular?
That's what I said.
typically less than a 10% variance in mileage tbh.
that gif. cracks me up
Took my toyota easily to 220k, parted with it with the engine still running nice.meh.

Never once put a drop of super. Just made sure the oil was changed regularly every 5k miles.
I think it's another mishap on his english. He probably meant to say that the "energy density" is higher with higher compression ratios (internal combustion engines increase their efficiency with higher pressure).
Cars built for lower compression ratios shouldn't have a (much) problem with 87 octane gas...
I can't tell the difference between high/low octane in my vehicle (except the cost). I guess it depends on what you drive. Unless you are getting gas at some ty gas station that doesn't properly maintain their tanks, I wouldn't think you'd have a problem with build-up.
My car requires premium now, but I remember driving a Mazda in the late '80's to early '90's that was supposed to be able to drive on normal gas.
But whenever I put S regular gas into it the car would just stop dead in the oddest places (like the middle of the intersection!)...I had to use premium gas or else. I think it's worth the price difference for me.
But Teysha, if I were like you and able to fix my own engines, I would probably be happy to use lower grades of gasoline. I've always been impressed with people who can do that. Anything mechanical is beyond me.
