What gas is called for a 1995 Gst?

Some say they use 91 and have issues, so they use 87 or 89.

You're only supposed to use Premium

92 and up i believe

i use 91 highest octane aroudn here without going and getting 110 racing... its better for your compression ne way.

91 or higher is considered premium. personally i never use anything lower than 93 in anything that I run hard (dirt bike, street bike, car, etc) but it all depends on what is available in your area

in california the highest is 91 octane. if you want race gas its about 5 bucks a gallon.

91 octane is good or 93 but no lower than 91.

You guys know how you say its premium gas right, does the gas station matter like say 76, Chevron, Shell vs like ARCO and the family business gas stations?

ive heard that pumps with three separate nozzles are better, i don't know why. and never buy gas if the pumper truck is there, it mixes up all the crap that is in the bottom of the underground tanks.

Correct

yeah, i guess if your running 1 hose for all 3 octanes your going to get a little bit of whats left in the line from before. and for the most part it doesn't matter where. but some places do add a little to their gas like chevron adds techron i think its called, supposed to help clean you fuel system, now does it work, couldn't tell ya.

i stick with what ever is at the top of the list be it 91 or 93.

:thumbsup:

you can use lower octane it will not hurt your car i have use 87 octane for my car nothing happen only thing that it retard timing.

thats when i didn't have cash.

Some "family" places may add stuff to the gas and not disclose it. I like to use the big name brands. Exxon, Mobil. Shell, Ammaco, BP, Citgo. But its all gas in the end, its not like you drive a top fuel dragster. ;)

I think a couple of years ago. some independ gas station (big/brand name gas) was filling like 87 octane in to 91 octane. So you are paying more for cheaper gas.

Which is why I always taste the gas before I put it in my car. I can taste the freaking octane Baby!!!!











No, not really.

yeah a block away, see EMT putting you in their bus and off to the hospital you go.

LOL

I only put 91 but thats because my car asked for it.. When I started uping the HP my car sounded diffrent and I could feel that I wasnt getting the most out of my parts so i went 4rum 87 to 91 and its all good now my car runs like a champ.

Your car will run wiht 87octane fuel..... That is untill you burn out your o2 sensors......

Your choise...... it's only like an extra 10cents a liter for 91 octane in canada....... Not a big deal at all....

What people had problems with 91 octane? It doesn't matter the octane level once your above the recommended octane.... You could put Avro fuel in your car (it's like 140octane) you won't see any power incresement, but your fuel ecconomy will go up by assloads..... the o2 sensors sniff out the octane level and adjust it to accomodate the proper mixture......

Carborated cars on the other had, just shove that crap in and talk about power boost....
