| Picking up my N/A tomorrow and just want to know which fuel would be best for it to run on. Would normal unleaded be fine or would I need a premium? |

| Don't run 91, you will be down on both power and economy. Its very apparent in my car, particularly at high revs - it just flattens right off at about 4000RPM. I would estimate economy to be down by as much as 15% for myself (probably because I feel I have to put my foot down a lot more) After much experimentation, I have found there is no noticeable difference in power between 95 and 98, however economy does drop of on 95, so I tend to fill up with 98 when I can, the few extra cents per litre do seem to come back around in extra K's. Note my driving is about 80% open road. |

| I usually run 98, but use 95 on occasion. I might try the ethanol blend 94 octane United offers, which is cheaper than other companies' 91 ULP, in concert with the occasional fill of 98 (there's no United locally anyway). |

| If it wont knock on 91, which it probably wont. Then use 91. |

| Which will just make a slow car even slower... don't use 91, the knock sensors will retard the ignition timing severely so it won't knock, and it'll just run out of guts at about 4000RPM. Also not good for the cat as retarded ignition timing will lead to unburnt fuel in the exhaust. |

| All specs i've seen for cars running the 2jz-ge specify 91 RON. I'm not certain, but will the ECU throw an error code if the knock sensors detect knock and timing is pulled back? |

| The SC300 manual says to use "Premium" - in the US Premium is 89-90 AKI, which is approx 94-95 RON, or 90-94 AKI, which is approx 95-99 RON. I would think the ECU will not throw an error unless knock exceeds the ECU's ability to retard the ignition. |

| i've found that with 91 i get more k's out of it than i do with 95/98, the performance is far more responsive with the higher RON but my one burns through it much faster. could also be because i have the VVTi that may be a difference??? |

Ours is also VVTi, but I've never knowingly used 91 so can't compare mileage (and unless you use the same run to test, and put about 3 fills of 91 through to clear all high octane out, it would be very hard to compare). |

| I use shell's V-Power here in Brisbane which is 98 and I have never put anything els on but I have sound that in some cases I have almost outdone some old turbo/v8 soarers that run on a lower octane fuel and I prefer it, I agree it gives better fuel economy when it comes to this beast. |

| I think all toyota soarers should have 98 fual becouse is a preformance engine an the fual last longer anyway, well for me it might be more expencive tho its more efficient. also mine gets so much power at 4000 revs it just throws you back is good for a 3 L car |

| If your going to driving your car hard most of the time(very tempting) your engine might ping on 91.Use 95 or 98, its realy suprising just how much smoother my car ran on higher octane fuel.But now i have gone na/t i use 98 all the time. |

That makes no sense. Unless you mean more KM/Dollar. With less power you'll use more fuel to travel the same distance.

I read a story like this once, it was by a primary school kid in years 2 or 3 and he was talking about "I think the dinosaurs should be alive because god made them strong". Something along those lines. Except he used better spelling, but you see how I mean he used the same logic. |

| I've just done first long trip (to Sydney and back) that the Soarer has had for ages. Other than first fill in Cobar (Shell 95) I used United Plus (ethanol blend 95 octane) at every fill, and car performed very well and averaged 10l/100km. This is a little better than other trips I've done, and for those I used 98 Ultimate or 95. United Plus is cheaper than 91 or 91E. I wish I could get it locally, I'd use it all the time. I'm tired of paying a 8-18 cents per litre premium for premium!! As a matter of interest, I've just switched from the stipulated Premium for our lease car (Koleos), to 91 or 91E. Again, sick of paying a premium for 95 octane fuel, and on a recent long trip (heavyish load, and roof box fitted for the trip) I used 91 and 91E exclusively. Got the best fuel economy ever for a trip, amazing considering the load (which, in addition to roofbox, also included a full 60l fridge). So I won't be using Premium again! I'd have tried United Plus, but can't have their fuel card with my lease mob. |

| 10l/100km I thought the 2jz would get down lower on a long run like that? To Sydney my vvti 1jz-gte got to about 6.7l/100km though that's exceptional. My 1uz gets 11l/100km around town mixed driving. What else does people with the 2jz get? Interested to know. |

I've never gotten better than 9l/100km, Scott, and I rarely hammer my cars. You have to remember than a trip like this contains a lot of hill work- from Sydney to Mudgee is all uphill, and much of a tankful was around Sydney itself (admittedly mostly motorways). In this case too, I had a heavy load on the return leg (including a dismantled garden mulcher and a huge ball cactus, which I struggled to get onto the back seat). I also sat on a tad (I won't define "tad") more than the 110km/hr limit Dubbo-Cobar. While Soarers should be economical at 110, I've noticed the economy in our Koleos "goes backwards" once we get to 110km/hr consistently. Also, I've checked my odometer- I'm sceptical of readings taken from odometers (and cars with economy displays) with unknown accuracy. The mean economy reading in our Koleos is optimistic by 0.2-0.5l/100km, all the time (and it takes generally about 2l more than what the "fuel usage" reading says). I had two Soarers together on Norfolk Is, and it seemed to me at the time that the non-VVTi car got better economy than the VVTi, although hard to check as I hadn't at that time checked speedos/odos, and they were fitted with different wheel/tyre combos. I guess my point is that United Plus is a good cheap alternative for those of us who have to use Premium grade fuel (pretty much everyone that drives a Soarer, of any type). At around 20 cents per litre cheaper (or more, compared to 98) it makes a huge difference to the cost of a fill. I never paid more than 123.4 cpl for United Plus on the whole trip- I left on Sydney on Saturday when 91 was getting to around 138.9cpl in the "cycle". Shell 95 in Cobar was 148.9 cpl. I passed a United in Mudgee (having filled in North Richmond) where Plus was 139.9cpl, but all other displayed fuels were closer to 150cpl. I'm pretty certain that a 3.0 n/a should get better economy than our car achieves, but other than a cap fix on ECU I'm at a loss to know what else I can do to improve it. Given soot around exhausts, on rear bar, after a long trip in WA I suspected O2 sensors, but mechanic checked them and told me they were OK. This didn't occur this trip. Given that I get 16l/100km around town (short trips) it's exciting to get 10l/100km on a long trip! |

| Yeah, I'm averaging around 9/100 at the moment on my trips from Hamilton to Auckland and back (around 230km per trip) - most of it is over fairly flat land with only 1 large hill to climb, and a big part of it is two lanes each way, so not much overtaking to worry about either. Living in a "small city", and not using the Soarer much around town as we use the Voltz for that, I don't spend much time sitting in traffic, but I'd be spitting tacks if it got as high as 16/100! Even living in Auckland and driven every day at rush hour it was never that bad! |

Matthew, I live 3.5kms or so from work, and when we were in WA about 1.2km from shops (although in WA we did occasional 100km return trip to beach). The car's not even warm before I reach the office driveway! I noticed with Koleos in winter- with front and rear defrosters and heater on full blast, car would only start warming up as I hit the road office's on! That sort of usage is not conducive to good economy...I've done the pushbike thing in the past but too old for that nonsense now. With two cars I can't justify the cost of a motorbike, so will just have to cop the horrible short run economy. It was no different on Norfolk Island, either, it's hard to find a long run on an 8km island |

As mentioned earlier, 16 to 16.5l/100km, pretty consistently back to WA and Norfolk Island. Since we left Norfolk, we've had a lease car which does most of the long runs, so Soarer used for short trips to the shop (in WA occasional runs to the beach). The main reason I took Soarer this time is that I've almost achieved nominated kms for lease car, with 8 weeks left to go in FBT year, and Soarer's due for an oil change (by time) but had done less than 1000kms since last change. Plus, it was a great drive! Actually, with rather infrequent use (sometimes it's 3-4 months between tank fills!) I suspect some of the fuel evaporates... |

I'm not overly happy with 16, but can se little way of improving it. As mentioned, my drives are often short. The Koleos gets the longer trips, but even that car gets only about 14-15l/100km purely on short trips. It's one of those things, engine's not operating properly until temp rises. Your mix of driving situations allows the car's engine to warm up. Mine don't. |

| Ah, that makes more sense. My daily commute was about 16km each way when living in the big smoke. Also if you are running on 3 month old fuel, it will be stale, which will have a significant impact on economy also. |
