My sister put regular gas in my frs!
 

So I left my sister borrow my car for a couple hours and she told me she's full my tank up and she did. But she put regular gas in my baby 😣😣😣 I'm sure one time won't hurt it. But what's the affects of using regular gas instead of premium?

car will make less power. just don't rev high or put heavy load and you will be fine. you can put a bottle or two of octane booster if that makes you feel any better, but really, don't worry and drive slowly for a few days.

btw, what is "regular"? in cali we have 87/89/91

Regular is the 87 over there. We also have 87/89/91. I'll TRY to keep the speed low lol. It will never happen again doee

You'll be fine, the engine will probably knock a bit but the computer will be able to sort things out for the most part. Just try to keep engine loads low.

Keep in mind that quite a few dealerships fill all the cars on the lot with regular.

Best to stick a bunch of octane boosters in there and keep the revs very low. Like 3000rpm. If you are able to drain it, that is your sure bet.

Buy her a siphon hose and tell her to get to work.

one of the reasons I drive MT

It will knock but not detrimentally to the engine that's what the knock sensors job is detect that knock and adjust the air fuel ratio and other variables to match. Octane boosters are a waste of money on these engines it's not a friggin lawn mower the best thing you can do is wait till less than a quarter tank of gas fill up with the highest octane and go back to normal. So to answer your question you'll notice a drop in power and maybe some knock/ping.

dont buy octane boost it does nothing. Just drive it easy for half the tank then fill with 93.

I'd aim to keep the revs in the 3000-4000rpm range, keeping it too low will load it up A LOT and put it in a big knock prone area of the rev range.

Just keep throttle input light and you'll be fine.

Even if you go ripping around it won't damage it, but you'll definitely be losing power and getting some knock.

What would happen if I just went ham with regular? Just asking. Lol

Nothing its a modern car with a knock sensor you'd just notice a bit of sluggishness and pinging/knock
