Who is still using premium gas.
It has nothing to do with affording the premium fuel. Its a matter of a choice. I choose not to put Premium in the car. It ran fine with 87. Both of them did.
I only put Premium fuel in my Snowmobile, Dirt bikes, Motorcycles, Waverunners and other gasoline engine toys. Daily work transportation is not worth the extra to me. I would rather know that I am saving a few dollars with each fill up.
And if your paying $200 a month for cable... your either getting ripped off or you need to find a hobby and stop watching so much TV. Maybe try enrolling in some math classes so you cna figure out $200x12-$2,400 not $24,000.

GTM TT kit with GT28's Was at 9.5 PSI, but I'm changing my MBC so I'm back to 6 now. This winter, I've gotten average 21 mpg. Like stated, that is mostly city. Before turbos it was 23 winter rims, and 21 summer, so I'm assuming I'll be on about 19 mpg this summer.

I just decided a few days ago after 8.5 years of driving G35's (2003 and 2008 x) that I'm not using premium anymore. I know I've read the manual (not sure some others on here have) and it states premium is "recommended" and then goes on to say regular is fine but that performance might be affected (which I can live with). I realize the coupe might be a different story with regard to recommended/required but I know at least with the 2003 and 2008 sedans, premium is not required. Statements like "if you bought a G you shouldn't be worried about the cost of gas" are just plain ignorant. Situations change. People change what they consider to be priorities. Just because I bought a G doesn't mean I can't change my mind about what I consider to be important or a priority.
Oh, and talk about engine damage is completely unfounded. Show me some evidence, otherwise I will assume you are stating opinion (likely with no real data or evidence to back it up) as fact.
Nice to see some logic and reason in this thread Kuneff!

The piston begins to move upwards during what's called the, "compression stroke," compressing a mixture of fuel and air.
In a normally operating engine, the spark from the spark plug ignites the mixture of fuel and air, causing an extremely rapid burning of the fuel in the cylinder. That's good. It's what creates the pressure that makes the piston travel down very fast, causing the crankshaft, your transmission, and ultimately the wheels — to turn.
However, it's possible for the mixture of gas and air to burn somewhere else in the cylinder, simply from the pressure (or compression) within the cylinder, and not from the spark. That's called "pre-ignition," and it's more likely in a high-compression engine.
When the fire you want (that's the one from the spark plug), collides with the fire you don't want (that's the one resulting from the pre-ignition), the result is a ping or, if the pre-ignition fire is big enough, a knock. The degree of severity, including the amount of noise generated, is determined by how big that unwanted flame is.
Q. How does high-octane gas help?
A. Compared to regular gas, high-octane gas requires higher temperature and pressure to ignite, so it can withstand higher compression without reigniting. As such, it's less likely to result in premature ignition, and therefore prevents pinging and/or knocking.
In other words, it's a form of protection for high compression engines.
In other words lower grade fuel may cause pinging, early detonation, and this all leads to other problems and also build up inside the cylinders, which then again causes other bad things such as loss of power, torn, cracked, or broken piston rings, which in turn cause blow by and more detonation, again causing catastrophic engine failure. Of course if you drive like an old a$$ lady and never go over 3k rpms then you should trade the G in and get a Buick or maybe a Hyundai.
Besides if you buy 87 rather than 91/93 octane fuel, your average savings would be around $200 dollars a year. If you can not afford that extra $200 a year, then maybe you should get the solar powered Moped, or even a moped in general.

Yea 24k meant 2400. Anyhow, Cable with HD, sport package, and internet = $197.34 a month. I guess I can afford it and that is why I am not worried $0.20 on the gallon.
However I am worried about you and your commute to and from work. You say you spend the cash to get premium for your weekend toy engines, yet the ONE vehicle that gets you to and from work to pay for the weekend toys you do not care about. Man get some priorities, Hell I put premium in all my engines. Chainsaws, trimmers, lawn tractor, etc.

Here is a decent explanation of what could happen when using lower than premium grade gasoline.
The piston begins to move upwards during what's called the, "compression stroke," compressing a mixture of fuel and air.
In a normally operating engine, the spark from the spark plug ignites the mixture of fuel and air, causing an extremely rapid burning of the fuel in the cylinder. That's good.

Also - that $200/yr is fanciful. My savings would be closer to 10 times that. It's not that much because I have switched from Premium for winter driving to mid-range. And because I am no longer a teen, nor do I act like one, I don't need to exceed 3K rpm in winter except when passing. I got over the need for burnouts and donuts 45 years ago.
Nothing but shell premium 93 V-power in my g35, nothing but non oxy in the 89 mustang GT. Gas is not something to cheap out on. Put the best gas in your equipment and it will last.

You seem to be equating higher octane with "best," which as we all know, is simply not the case. The question remains, "best for which engine." The use of the word "premium" is just advertising hype, like "rinse, repeat" on a bottle of shampoo.

^Exactly! I use whatever My engine is tuned for. In My high compression G, all I put in is premium. However for my trucks or anything I am using that is tuned for 87, I will not hesitate to use lower grade.
