3sgte gas, What do you feed your car? Options

[Legit94GT]

ok this is for anyone who has a celica that has 3sgte in it...
I am almost at the point of buying my front clip but am curious as to what gas everyone in tha states runs it on. I cant remember where i read it but i think it needs like premium gas to run, or something above 93 octane... so when you guys fill up what do you put in to feed you 3sgte?

It depends upon what ECU your running.

If you have a jap ECU then you should run high octane fuel as that is what it is mapped to run on...if you can get hold of a UK ECU then you can run pretty much what you like as it is mapped to handle lower octane petrol. If you have an after market ECU then you should run it on whatever it was mapped with. On the whole most people like to run the best pertrol you can buy/have access to.

Petrol quality can vary wildly, it does all start from the same point...under the ground...from there it can be different from station to station. The likes of Shell and BP are probably the best to buy.....shell has a higher octain rating and seems to be more resistant to knock than other fuels...BP (I dont know why) produces more torque...both are brewed to be high octain fuels and dont contain as many additives as some of the cheaper petrol...one of the high octain supermarket fuels in the UK is just brimming with additives, its classed as 99ron but contains alot of crap...one of them being silicone which can effect the O2 sensor.
Also the popularity of the garage can help....a busy garage will have a constant supply of fresh fuel...petrol does have a finite life and goes "off" suprizingly quickly. If you want the best possible power from your petrol...pck a brand of petrol where the high octain petrol was made to be that way...not regular petrol with additives...also go for popular busy garages that will have fresh fuel.
