No sydney refinery, Import from Singapore , unless some out of Queensland. Will be the tanks at the servos. niZmO_Man, where do you think Mobil fuel comes from ?

In the 10 years of driving I've done, I filled up twice out of necessity with Caltex. Once back when E10 was being pushed, caused my R31 to stall when cold and ran like shit (yes, E10), obviously burned through the fuel. Switched to Mobil (regular 91), no issues. Floated between Mobil and Shell, got extra 50km from a tank of 50L from Mobil lol (highway driving SW Sydney to Kiama and back). Even tried Mobil E10, same performance as regular but slightly less mileage.

Seat of pants (no knock sensor readings or anything), my cars always liked Mobil fuels. BP is fine but usually more expensive, so don't bother. Plus Mobil is closest to where I lived (and live), and either on par or cheaper than Caltex. Win win.

Brother's experience: Holden Cruze 1.4 turbo 6spd auto, Caltex E10 to Mobil E10, Mobil got extra 20-30km from his normal driving and 'ran better'. Same shit on 2014 Corolla 1.8L 4spd auto.

I've also advised a handful of non-car friends to switch away from Caltex, but they were too random with filling up 'whatever unleaded fuel' they could find. I did have one comment that switching away from Woolworths led to small but noticeable increase in performance but mileage was the same.

But who cares about real world experiences right?

Mobil fuel comes from the same place as the other brands, out of the ground. What's your point? They use the same depot? They're all the same fuel?

Depends what state you are in which refinery it comes from. Since there are no operating refineries in NSW most fuel is imported from Singapore or a small amount comes from Brisbane. Shell is imported , though a small amount comes from Victoria. BP refinery in Brisbane is shutting down soon . So what I am saying is the vast majority of finished product is imported . There is some refinery interchange between companies . Also all fuel has a set of govt regulations to stick to. RON +/- .5 of a number . Yes some do have additives . You also have differing fuel between company owned or woolies / coles. etc .

To say one is rubbish and others are not, is just anecdotal , Depends on where it was sourced, how long it was in transit, how long has it been sitting in tanks etc

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
