Your friend doesn't know what he's talking about.
Use the manufacturers suggested fuel, it'll be in your manual.
If it fucking tells you to use 93, then use 93.

It burns quicker and more completely, providing better throttle response, cleaner combustion, and greater fuel economy. It may also wear your engine a bit quicker, not enough to be of any notice though. A brand new Impreza sport had better be able to handle it or you've got a serious issue to take up with Subaru.

holy shit, based kilmer

i remember watching his youtube videos on cars SO LONG AGO, when i didnt know shit.

i fucking love that guy. but in this vid you posted he sounds and looks like he's finally aging. even so, hes got that energetic and down to business style that i fucking love.

Well, none committal answer incoming, it all depends on what is used by any given company as additives to adjust the octane, some of the cleanest burning additives are very low octane (think in the 20s RON) they are also cheap. Fuel companies like to make a big thing about the cleaning properties of the high octane fuel, and it is true they add more of the "detergent" chemicals to those fuels, mainly because it's good marketing. This isn't true for all higher octane fuels and isn't directly related to the octane rating of the fuel so much as it's positioning as a "premium" product.

I always put premium, the $2 extra when I fill up won't break my bank. I guess if you're penny crushing, go ahead and put pleb tier gasoline.

Is it okay to mix 93 and 85 octane? Currently driving my parents' 2002 Accord and my father insists that I use premium gas. I fucking know that it's a waste but I can't fill it up with 85 under his watch. I want to "switch over", though. Would this be okay?

STOP RIGHT THERE CRIMINAL SCUM

You can use any octane on any car. Although I recommend 93 at least. Here we dont even have 85, just 95 and 98.

But you can run it without probs with 85 but you will miss some ps.
On some cars you dont really see a difference.

>>14693593
Yes

>You can use any octane on any car

Not quite, but it's very lenient, yes.

>>14693493
The octane-value describes the clocking-resistance of the gasoline. The higher the less likely you get clocking while driving. Octane 93 is more clock-resistant but not more. If your engine is optimized for a higher combustion you will need it. if not it gives you nothing. it is only a value for the purification. But the "unpure" parts are also combustible, not garbage, wich is why you will not gain power unless you rewrite your ESC for higher compression. If you do so you will need it.

>>14693603
You do know we (the rest of the world) measure octane differently to the yanks. Our equivalent to US 85.

>americans actually have octane as low as 85

Oh my god you are all a bunch of fucking morons. Why don't you fucking Google octane ratings and figure it out yourself. unless your engine is pushing 10.5-1 compression, you don't need premium fuel.

Fucking "computer" guy can't fucking Google shit...fuck.

>>14693753
We don't, is the thing.

This guy is correct, only he means knocking or pinging. Pre detonation.

The octane rating is a measurement of how much pressure is needed before detonation occurs.

High compression engines might experience the air fuel mix igniting before spark by pressure at high running temps, hence the need for gas that only ignites at a certain pressure.

High octane baby
