If there is premium gas in my Volvo, is it safe to add octane booster to the fuel tank?

The car is a 95 Volvo 850. The engine actually requires premium gas. Last night, I may have put regular gas in it by accident. The regular gas is 87 octane. But the thing is that I am not sure that the gas is regular- it could be premium. Is it safe for me to add an octane booster? It's a small orange bottle of STP octane booster. It treats 21 gallons. I am worried because if the gas is regular, it could severely damage the engine. That is why I want to add the octane booster. The product is STP "The racer's edge" octane booster. It apparently has or is made from jet fuel. Is it safe for me to add this to the gas tank? Thanks.

Where do youtubers get their tour buses?

I see like alot of youtubers whenever they go on your they sometimes have a tour bus like I saw Bethany mota's tour bus and I was just wondering where do they get them do they buy them or rent them thx. (:

You look like a real smart guy and this is a smart thing to do. Just put a dual turbo with nitrous and fuel injection and you will have more horsepower. I sure hope this helps answer your question, because it is a good question, everybody with a 13 year old car with a million miles on it wants more power from that old worn out motor. Hope this helps...

Don't you think the wwe should stop calling themselves,...?

,..the wwe, and instead call themselves the ww, and stop calling it "world wrestling entertainment", and instead just call it "world wrestling"? it's ridiculous for...

This really needs to be investigated by a garage.

It could be tyre treads on one side, or tyre pressures, or faulty shock absorbers, or faulty brakes, or ... well, the list goes on.

For your own safety, get it checked out soon.

Where can I store a car?

My uncle wants to get rid of his old '76 camaro and I want to buy it from him, but I have no where to put it. I have a garage, but its full of other cars that aren't going outside, and I'm not putting a 38 year old classic car in the driveway outside. We thought of getting one of those canvas pop up garage bay things, but our town doesn't allow them for some reason, probably because they look bad or they don't want another structure on your property or something, I don't know. But anyway, there's no room in the garage, and I cant get one of the canvas pop up bays. What other options do I have? I really want this car but this is the only thing holding me back from getting it. Within a reasonable budget too, I don't want to spend more on storing the car than on the car itself. I have plenty of room in my yard too, so space isn't a huge issue. Any suggestions?
