3sgte high maintence :( Options

[Stipt]

From what I heard is that you need to use some kind of race fuel to keep your car bumpin for awhile or you can use premium gas and have it run like **** and die sooner. I never knew that until I talked to a few people. Think it should be posted with the swap info?

[Charlie97L]

no, you have to run 93 or 95 if you have it. but any turbo engine (or JDM engine) is gonna require that. i have to run 93 in my 7afte. yes, turbo engines are MUCH higher maintenance, but that's the trade off for performance. your car won't die with a JDM 3sgte and 93. if that was the case, everyone with a 3sgte would have it not running. who are you talking to?

huh?

the 3s-gte may be a little more high maintenence than lets say the 5s-fe, but the amount of power you make out of the engine is well worth the repairs. and you can usually expect more things to go wrong with a more complicated engine especially on a turbo setup.

As far as having to run race fuel, thats rediculous, you would only run race fuel if you were pushing some high numbers. as far as a stock 3s-gte, there is no reason to ever run race fuel. premium fuel can always help your car run smoother, and I would recommend it on the 3s-gte, but you could probably get by on using some 89 unleaded. but personally I always tend to use 93.

Who told you that you had to run race fuel? did they perhaps say that you needed race fuel if you have an extensive mod list?

Do not use anything lower than 93, and thats even low for a JDM engine. In Japan, the fuel is alot richer, and it goes above 100. JDM engines are built with that type of fuel in mind...thats why you need 93+. Someone on here told me to use octane booster, which didnt even kno they had.

octane booster is a waste of money, IMO.

[Drunken_Style]

I thought the octane scale they used in Japan was different then ours.

Sooo it doesnt work? I've never used it.

[Stipt]

I thought that if I used 93 octane then it would wear down the engine quicker. **** in my Celica I use 93 octane already LoL! So.........it won't be bad if I use 93 octane for daily drivin? But use race fuel if I'm going out for the night and burnin rubba.....

[boosted_K2]

sorry but you are retarted if you are running 93 through your car stock... such a waste of money.

[Stipt]

Why? Its 2 cents more than the 89 octane here.......

[boosted_K2]

2 cents isnt bad, but it adds up everytime you fill up, and theres no sense running 93 through a car designed for 87-89, you gotta remember these things arent performance machines in their US form, theyre still grocery-getters.

[Stipt]

*shruges*...........true.........although I only put gas like once every two weeks

[KAMiX]

So I'm guessing that in the US premium is 93 then. We have 98 octance over in Australia, and as Supersprynt said, the japanese design their engines for high octane fuel - so much so that I often hear of people who's imports are having problems running on our 98!!

Someone else could probably sum up the problems (if any) that low quality fuel will create.. I've never had a 3s-gte (SOON!) so I can't give any firsthand experience. But I always put 98 in my car because the engine feels healthier and the car feels better all round.

[Rivo]

You people are forgetting us folks in cali. We don't get no 93. We only have 91 we have special turbo cars out here. I'll be running 91 with my BEAMS though

Why wouldnt you want to get the best performance possible by using 91 or 93 octane instead of the lower grades? Even the owners manual says to run premium fuel for best performance, (at least in the GT-same reasons apply to an ST). You'll spend a few $$ a year extra, but so what? an extra $1.50 or so per tank isnt all that steep. I have to question someone who would spend $500+ for an exhaust system to try to gain a few HP, then run the cheapest fuel they can get. remember, the computer is retarding your timing when it senses detonation, as in when accelerating hard, so higher octane= more timing advance left in= better perf... (and I've seen whats left of pistons after a little too much detonation. I'm not going there)

[zigy]

yo just go to "Delta Sonic" and fill up some 98 yo..... (it's about $3 a gallon)

i was the one who said that...

you can buy octane in little cans at walmart and auto part stores...probably other places too.

i have used it a few times...not any noticeable gain in performance.

but to get your octane rating up

then you can use that.

[Mage]

I heard 93 octane is too rich for economy engines, and that using it excessively could actually be detrimental

[Supersprynt]

I put 93 in my car when I had the stock engine in it, why? Because i had 185,000 miles, and the higher grade does help to extend engine life. In JDM engines u have to use the high grade because its actually low grade compared to what the engine is designed for, i think thats the bottom line here.

It is...when you see that they have 101 octane over there, that's a research octane number... Here we have the R+M/2 method for octane... motor octane is always lower and tends to vary about 10 points from research octane (so 101 RON = 91 MON = 96 R+M/2)

Not always accurate but it's just a general rule of thumb.. 93 Octane in the states is perfectly fine for a JDM engine... Keep in mind they do have lower octane fuel over there as well. That 101 RON stuff is expensive and a lot of people don't use it. The 3sgte I got obviously never ran on super high octane - there was carbon everywhere in it.
