Somebody's salty about gobbling up the octane = power bs

http://www.eia.gov/todayinenergy/detail.php?id=25692

quote:

Smaller, turbocharged engines can be used to raise fuel economy while meeting or exceeding the power and torque of larger engines, allowing engine downsizing and improved fuel economy with little or no performance compromise. Turbochargers work by using a turbine driven off the exhaust gas to pressurize the intake air. The pressurized intake air allows a turbocharged engine to produce more power compared with a naturally aspirated engine of the same size.

Because turbocharging forces more air into the combustion cylinder, it increases cylinder pressure and compression. However, increased compression can lead to an increased risk for engine knock (the premature combustion of fuel), which can damage the engine. Therefore, turbocharged engines typically require more design and operational features to prevent engine knock than naturally aspirated engines.

The octane rating of gasoline is an indicator of its resistance to spontaneous combustion. The higher the octane rating, the greater the resistance to preignition, the fundamental cause of engine knock. Use of higher-octane gasoline can offset the increased risk of engine knock caused by increasing engine compression. This higher octane is the reason why premium fuel has historically been required in performance and luxury vehicles that maximize power and torque.

In any case, unless your car is really old or was built in a shed the computer in it is advanced enough to mess with the timings to preempt knock, which will reduce performance and/or fuel economy but also prevent knock from destroying your engine. This goes for both turbos and NAs, its just that with the turbo is the only time I've actually noticed the reduction in performance.

Also modern technology is essentially magic. Mazda only recommends 91 RON (87 AKI) for their skyactiv NA engines despite a 14:1 compression ratio. My 1990s beemer had a ratio of 10.5:1 and recommended 95 lmao

It's not that octane=power, it's that your forced induction/naturally aspirated advice is stupid. Running 87 on a modern naturally aspirated car probably won't hurt it, but the power/efficiency loss is a real thing. It may not be as pronounced as on a turbo car, but it's there. Use what the manufacturer recommends.

Use what the manufacturer recommends.

But why? You've just stated exactly the same information as me, just with a different conclusion. 95 and 98 costs about 11-16% more than 91 RON and in 4 years of hard driving I never noticed any difference despite a recommendation to use 95.

I'll give a more valid criticism of my 'stupid advice'-- that I'm extrapolating from a small sample tested unscientifically. But if you went out tomorrow and filled 91 for the first time after years of filling 95/98 and noticed no significant difference in performance or fuel economy and knowing that modern engines automatically preempt knock, then why wouldn't you save that significant, both psychologically and economically, 11% in fuel cost?

Here's some words (containing some additional qualifications that should be obvious) from people who did actually test it in a slightly more rigorous fashion

http://www.caranddriver.com/features/regular-or-premium

quote:

The results were more dramatic with the test cars that require premium fuel. The turbocharged Saab's sophisticated Trionic engine-control system dialed the power back 9.8 percent on regular gas, and performance dropped 10.1 percent at the track. Burning regular in our BMW M3 diminished track performance by 6.6 percent, but neither the BMW nor the Saab suffered any drivability problems while burning regular unleaded fuel. Unfortunately, the M3's sophisticated electronics made it impossible to test the car on the dyno (see caption at top).

Our tests confirm that for most cars there is no compelling reason to buy more expensive fuel than the factory recommends, as any performance gain realized will surely be far less than the percentage hike in price. Cheapskates burning regular in cars designed to run on premium fuel can expect to trim performance by about the same percent they save at the pump. If the car is sufficiently new and sophisticated, it may not suffer any ill effects, but all such skinflints should be ready to switch back to premium at the first sign of knock or other drivability woes. And finally, if a car calibrated for regular fuel begins to knock on anything less than premium or midgrade, owners should invest in a tuneup, emissions-control-system repair, or detergent additives to solve, rather than bandage, the root problem. Class dismissed.

Alright, for the Saab you get about a performance drop about proportional to the fuel unit price savings, but in an M3 that 6.6% is still about half that of the 10% difference in 95/91 RON, though its likely that anyone who owns a modern M3 would care very much about that 6.6% in lap times while giving zero fucks about saving money at the pump

So all in all the more scientific test was neutral. It doesn't kill your engine.. probably (and lets face it, I've never heard of untuned, unchipped high performance cars made in the last ten years getting knock warning, so this reads like a cover-your-rear end legal disclaimer), and even in performance cars the decrease in performance was at most the savings unit fuel cost.

I gave that stupid advice because apart from many people not actually knowing that their recommended fuel grade is, lots of people buy premium fuel despite knowing that their maker recommends the cheapest 91 because they bought the bullshit about high octane = better performance/economy all the time, or that advertisement where filling V-POWER = little people scrubbing the insides of your pistons as you drive. AAA estimates this unnecessary spending in the US to be in the tune of $2.1 billion a year (http://www.marketwatch.com/story/us-drivers-waste-billions-paying-for-premium-gas-aaa-says-2016-09-20)

A quote from that article,

quote:

(AAA said that only 16% of vehicles sold in the U.S. require premium fuel)

Now, maybe SA really is a forum filled with trust fund babies and billionaires, and by recommending 91 if your car has an NA engine I'm dooming many unfortunate goons to an embarrassing afternoon the next time they bring their aventador to a local lambo club's drag race event, or maybe I've given their ferrari enzos a sentence of death-via-91 RON, but I would wager that its more likely the people reading my post fall into the category of people-who-fill-premium-for-no-reason, don't you think?

FlexFuel just means your engine can run on higher ethanol/methanol fuels than older engines designed for 0 ethanol (that can sort of run but less well on E10 THANKS FEDERAL GOVERNMENT FOR CORN SUBSIDIES ASSHOLES) so if you put premium in it... you'll just waste money

Whole lotta words demonstrating that you don't know. Basically by using lower octane than you're supposed to, the fuel doesn't burn properly. The manufacturer recommends fuel based on compression and they design the engine around a certain octane. If you're trying some scheme to save money, you're just going to burn your valves and it will cost you in the long run.

Quartz Co. Very similar to canada goose in materials and pricing, although I like to think it's a bit higher quality since it's all handmade here om Quebec in a small factory and much less of them are being made and it's not a well known brand so they can't just ride their logo. It certainly looks a bit higher quality (especially the fur which is also removable which is a nice bonus)

Also has the advantage of not being canada goose so people won't think I'm a tool quite as much. Before hearing about this I was thinking of buying a canada goose with the black logo so it wouldn't stand out as much but would have settled for a regular canada goose in a worst case scenario because I'm sick and tired of being cold and other great parkas are fugly or more expensive.

Would you mind coming back and posting a trip report after you've used it for a few weeks? I'm actually in the same position you are - I have a Nexus 6P right now and it's a fine phone, but the reviews on the Pixel XL are very enticing. I've only had my Nexus for a year but I'm wondering if it's worth the upgrade. Would really appreciate it!

Follow up as requested - The Pixel XL is the best phone I've ever used. That being said, the 6P was the best phone I had ever used before that. There are two things I miss about the 6P - tilt to wake ambient display and stereo front facing speakers, although the downfiring Pixel speaker is way better than I expected. If I didn't keep putting my fingers over it I wouldn't mind.

Honestly, unless you're rolling in money, I'd wait for next year. It's just not a big enough leap, especially once you get 7.1 on the 6P (I was in the beta program). It's a shame the 6P didn't get the recognition it deserves.

Loving the camera though, took this shot tonight in downtown Vancouver (no editing, no natural light, pouring rain)
