Who else has fallen for the /regular gas/ meme? I tried Premium

because my car was built for 87 octane

>>16094396
I put premium in everything because I ran actual gas mileage on everything and it's cheaper because the 40¢ spread on $3 is less than the increased mpg.

The only thing I don't use it in is my mc because unless I'm filling a fuel can in the middle of a premium tank I'm pretty sure I only get the last bit of shit gas from the fit before. Fucking peanut tank.

>>16094406
Mine was too and runs on 87 octane. I've been driving it for a year and a half using it but couldn't use it to it's full potential.

The manual says 87 and up and does benefit from higher octanes.

Higher octanes also have more detergents in them to help your engine out.

>>16094416
>I put premium in everything because I ran actual gas mileage on everything and it's cheaper because the 40¢ spread on $3 is less than the increased mpg.

I didn't realize this either. Premium fuel has more energy per unit volume so you get less from more.

>>16094423
You're an idiot.

If your engine knocks, try a different brand of gas and if it still knocks step up to a high enough octane it doesn't. You'll not only get better fuel economy you'll also keep your engine from popping.

If your car runs fine on regular, you're an idiot for putting better gas in it. You may get very slightly improved fuel economy but nowhere near the 10%+ more that the better fuel costs.

>>16094491
>If your engine knocks, try a different brand of gas and if it still knocks step up to a high enough octane it doesn't.

Yes I didn't even realize this. My engine would knock under certain circumstances and I didn't even think to use premium fuel. Now engine knocking has completely stopped and my engine sounds and feels smoother.

Feels good man

What happens with engine knock? At high rpm my engine feels weird and the battery light always comes on in high rpm 2-3 gear driving..

whoops

>>16094527
Engine knock in my case, if the engine was under higher stress like higher than 3k rpm the engine would make a high frequency fast ticking noise. I didn't even know that was what it was called but this happened using regular fuel.

I found this out searching online and found my engine has a high compression. Meaning under higher stress from faster and hotter reactions in the cylinder, the fuel/air mixture would ignite prematurely. This is a problem and the the ECU would try to alleviate it by retarding the timing on the ignition. However using premium fuel, it takes a higher temperature for ignition which leads to a more controlled combustion without having to rely on your ECU to retard the timing.

That may be what's happening with you but I'm not sure about the battery light issue. That didn't happen to me.

>>16094556
Kek once the engine has been running for 5 minutes it should have the same temperature internally whether it's 50 or 90 degrees outside.

The best gas for yor engine is the lowest octane that doesn't knock. End of story.

>>16094396
>So why haven't you joined the high octane master race /o/?

I don't need higher octane because my car was designed for 87 octane. Nor is the computer retarding to prevent knock with the wrong fuel (thus wasting mileage). However, I do use TOP TIER GASOLINE not only for the added detergents, but for its other stricter requirements such as sulfur content, additive content, etcetera.

>>16094406
>Import JDM engine that needs US equavilent of 96 octane.
>Engine knocked on 93 octane till I got a tune
>can actually feel the sluggyness with the pulled timing.

>>16094958
Where do you get top tier gasoline? How can you tell?

>>16094967
Wtf I've never seen 96 octane at any conventional gas station

Would octane matter on an engine (5VZ) with higher miles (215k)?

It uses 87 but recently if im running it for 3+ hours i notice it vibrates a little bit more (knock?) nothing too noticeable though.

The engine runs 3 coilpacks along one side with dual electrode plugs, and the other side are single electrode.

You guys are all complete fucking morons that don't have the slightest clue about automobile engines. Early detonation has absolutely zero impact on performance. All this shit you conjure up about it "running better" is placebo/in your head

>>16095002
Well I would consider an engine using 91 octane that doesn't knock superior to the same engine that does knock using 87 octane

>Because of the way detonation breaks down the boundary layer of protective gas surrounding components in the cylinder, such as the spark plug electrode, these components can start to get very hot over sustained periods of detonation and glow. Eventually this can lead to the far more catastrophic pre-Ignition as described above.

>While it is not uncommon for an automobile engine to continue on for thousands of kilometers with mild detonation, pre-ignition can destroy an engine in just a few strokes of the piston.

https://en.wikipedia.org/wiki/Engine_knocking

Uhh yah I don't want to destroy my engine bub, nice bait though

>>16094984
Hmm I'm not sure, what's the compression ratio on the engine? I would try it at least once and try to notice the difference. For me it was game changing

>>16094932
That sounds complicated, how specifically was it tuned?

>>16094982
Japanese RON 100 octane is around 96 US octane. So if you import say a, SR20DET, RB26DETT, or JDM 2JZGTE & use the Jap ECU out the box without touching the tune, there's a good chance it's tuned for RON 100

All else being the same, 87 Octane will net you better fuel economy if your engine is designed around it, period.

There are a bunch of different reasons why an OLDER car that was originally intended to take 87 Octane might run better with 93 Octane - namely lots of deposits that get heated up during continuous combustion cycles and cause an effective increase in compression. That would be one reason why some cars run better on premium even though they weren't originally designed to run on premium.

Well memed

I'm pretty sure my car would die if I gave it 87. I usually feed it 94 octane, which is like 101 for Europeans

Of all the issues you want to argue, gas quality isnt one of them.

Put 91 in a high compression car that asks for it and regular otherwise. Stop overthinking it.

>>16094396
I drive an '89 Accord with 437k miles, and I'd been putting premium in it just thinking that the additives would be good for the engine (which has never been out of the car).

Two years ago I barely passed smog- hydrocarbon emissions at low speed were right at the limit. My guess was that it wasn't burning all the fuel at low speed, so for the last test I used regular gas and it passed easily.

Not sure what I'll use going forward. I should run a few tanks of each to see if there's a difference in fuel economy, I guess.

Early detonation has absolutely zero impact on performance

it will when you blow a hole in your piston from the severe pressure spike caused by the ping.

and modern engines, what with the fuel injection and the knock sensors, they can sense ping and will retard the timing to compensate for it. Here's a fun fact, fucko; retarded(like you) timing causes loss of power.

Friend has a dyno shop
Got the stock pcm tuned with basically more fuel in the top end and advanced the timing a shitload so i got ~5 counts of knock under boost with a steady 13:1 Afr.
Hooked up the water injection and no more knock at all. For the first month I kept a laptop data logging in the car and beat the shit out of it and never got a single count of knock with straight tap water.
Under 500$ you can get a water/meth system and get a tune with basically just a shitload of timing advance and pull the knock with water.

Your point? That's almost exactly what the difference should be based on ethanol's much lower energy density.

>>16098343
In most of Colorado "regular" gas is 85, then it goes 87, then 89. The altitude messes with the timing or some bullshit so basically you can run 2 octane less than normal without knocking.

>>16094679
The best gas for your engine is what the manufacturer designed the engine for.

>>16094527
Alternator?

>>16098030
Manual says 87 OR HIGHER, it's the "OR HIGHER" part I neglected.

The compression ratio is a whopping 11.5:1 for fuck sake

>>16098716
You get a lower manifold pressure so the air/fuel mixture in your cylindres doesn´t get to a high pressure and doesn´z knockthat easy.

>>16098825

There are engines now that run on 87 with 14:1 compression ratio

>>16094679

Engine wear typically happens when its cold it has little to do with the flow when its cold because even an idiot knows 0w to 5w is basically nothing even when cold.

There is a reason why your cap says 5w30.

Since most cars have knocking sensors and can alter the ignition timing to prevent it it is unlikely to have suffered damage.

>>16101925
Some cars run a high copression ratio right from the factory or have a turbo.
If you use low octane fuel for them these engines will knock.
To save the Engine car Manufacturers build in a device calle knocking sensor wich tells the ECU the engine knocks.
The ECU can adjust the ignition timing and/or boost to prevent knocking wich results in less efficiency and lower power.
If your Engine doesn´t have Problems with knocking you won´t get any benifit from high octane fuel, maybe you´ll actualy loose power due to the lower burning speed of high octane fuel.
I tested this on my Simson S51 wich needs 73 RON octane, on 95 RON it runns 70 km/h, ond 100 RON it only goes 60-65 km/h.

The lower number tells you how the oils viscosity is at low temperetures.
It basicly tells how it compares to a single are oil in the winter, the more fluid it says on low temperatures the better.
The higher number tells you hw the viscosity changes while getting warm, a higher nuber tells you the oil is staying viscose instead of getting to liquid.
Again this number compares it to a single are oil at a certain temperature.

That would be the Grob G 850 Strato 2C, it compresses 45:1.

>>16104000
Did you read the second sentence?

>>16094423
just add clorox.

>>16104482
Sorry, but we in Europe still have 102 octane above that.

>>16104531
You're really illiterate aren't you?
Go back to the first post and read it again.

>>16104540
No, I am not illiterate, our 102 ROZ gas is the best we can get, not 95-98 ROZ.
In your scale it might be lower than 100 but it is still pretty high.

I said LOWEST here is 95 ROZ. How are you not illiterate, if you can't even see this

>>16104575
Sorry, it is almost 0:15 here and I haven´t slept for 18 hours, last night were only 4 hours of sleep.

>>16104587
No problem, man. I didn't really want to come off as rude. Thought you were trolling at first. Seems like we're in the same timezone, too.

>>16104595
Are you from germany to?

>>16104609
Jap, bin ich. Hier auf /o/ sind doch recht viele Deutsche unterwegs, die sich aber kaum zu erkennen geben.

>>16104625
Ist aber auch irgendwie klar das wir auf dem mit am techniklastigsten Board lauern.
KEK

>>16104127
That's a weird looking plane

>>16105010
Indeed, but it is the bigges full carbon fibre plane in the world.
Also it flys up to 26 km high while using a turbine as a turbocharger.

>>16105052
But can it do barrel rolls

>new car
>regular

HEY YOU NORMALFAG FUCKS STOP IT I NEED IT FOR MY SHITTY 85' V8 LANDBARGE

>>16105549
What do you mean?

>>16105533
Every plane can do barrel rolls, if it is buld like most Grob planes it could do barrel rolls upside down.

And here I am filling my 1.0 shit box with 98 octane. Europe master race

>>16107180
>tfw he´s not using 102 octane

>>16107060
A Mi-24 can do barrel rolls

>>16107270
Im scared of 102 octane cuz it can melt steel beams on my car

>>16103668
read forums. My car has a Zetec engine, which is used in several cars, notably the Civic and the Focus, and owners there favor 0w20 and 5w20 for the sake of mpgs over the traditional 5w30/10w30.

>5w cold density at freezing point is a tad over .84
>0w is a tad under .82

Since you seem horribly uninformed, oil is less dense than water at freezing temperature, because you don't want a block of ice in your engine bay overnight.
At the same time, oil is less dense than water at room temp or anywhere up to boiling point, because that's just the chemical properties of it.
Feel free to consult 540 rat blog, bob is oil, or any other source and they'll all tell you: you are wrong, unless you have a displacement monster engine diesel or a track car.

>>16103863
in the US at least, Ford OE wants you to run 5w20 instead of 5w30 for emissions sakes. If your car can handle running thinner oil (IE its newer or low wear) then you will want to do it. Only move up to thicker oil if your car is having detrimental side effects like engine knock, loss of power, premature oil degradation.

>>16107321
Planes use 100 octane rated fuel wich is actualy 110 octane and it still doesn´t melt steel beams.

>>16099112
Who /electric/ master race?

ausfag here i use 95 ethanol blend ron which is like 90 aki?

>>16094396
I did, when I bought a car with high compression that requires 91 or higher. Running higher than 87 in a car that doesn't need it is snake oil, does literally nothing for the car.

>>16107673
I have a modifyed moped wich accelerates insanely to 30 km/h since i´ve modified the shunt.

>>16107690
Enjoy your blown engine from detonation

>>16107690
ignore this
>>16107943
It's early

>>16107956
Yeah I fucked up my post too. Should have said that I used to use regular until I bought a car that requires 91 or better.

>>16095603
