Anyone use regular gas in their Si?

You have zero idea if your car came with 87 in it. The chances are, it did. It's no big deal.

Correct, I guess I would be a bit put off by a dealer who tells buyers they put 87 in a vehicle that is recommended to have 91, that gives off a 'we don't give a damn' vibe. Also, I suppose if you respect the break in period, you should have all of the 87 out of it's system by the time the spirited driving begins

93 all day errr fill up.
My wife's sport we put 89...no need because her car is the commuter. Her oil is the 0W20 Mobil 1 ESP formula. That oil is green lol.

LOL I'm pretty sure he wasn't advocating using 87 but simply saying (like I was) that it won't cause any damage if you did. There's a difference in saying something is OK and telling you to do it.

How long will this thread go on? The horse has been beaten to death and now we're shooting it.

The horse has been beaten, but like an oil thread, it will be beaten, shot, cut into pieces and served to my dog

I'm not a fan of the President (as is probably clear), but vaping has been proven as the cause of several deaths. Anyway, another topic for another time...

Yeah, cigarettes kill 320,000 people every year, but it's cool because tobacco companies have money to pay politicians with so that's okay they can stay and leave less options for a nicotine addicted population.

I'd be worried about Legionnaires.

Premium fuel is very important in a turbo charged vehicle. You want to avoid detonation.

What exactly is detonation?

It's another word for knocking, the fuel/air combusts in the chamber before the spark plug has a change to ignite it on proper timing.

What he said but another way to put it would be when the fuel/air mixture is ignited prematurely due to compression rather than the spark plug as intended.

It should over time but the best thing to do would be to reset the computer to let it adjust for the different fuel.

I'm sure there's already a thread about this... I'll give it a shot.

That's not true. The regular turbo charged Civics as well as the 1.5T Accord both use regular unleaded, as well as the CR-V EX etc. Only the Civic Si, the CTR and the Accord Sport 2.0T use Premium. If you use Premium on these models, you are just wasting money as they do not benefit from Premium gasoline. Again, I am only referring to stock engines. Tuning them might change things

Good to know. I still wouldn’t use any fuel below 91 in any of my turbocharged engines. But that’s my opinion.
