100RON will give more power.

However, this is only if your ECU is tuned for the 5% Ethanol otherwise it will run lean.

Consesus is:

It's good if you can program your ECU but the small number of stations that carry the fuel (at this point in time) makes it not worth it to use it.

Put 40 litres in today and after a while i done some testing. My knock has reduced at least 20/30% which is great as a safety feature. Seems to be going quite strong as per usual but if it picked up a few kw's it would be hard to pick, but i will definately will be using it more for the reduced knock

Well guys, even though i used about 1.5 tanks worth of petrol today, I could definitely notice the reduced knock levels, a result of the 100ron fuel.

Id be happy to use it often, but its a pain finding a petrol station that stocks it. Most of them are about a 10 minute drive away, at least

After reading the posts, it seems that Optimax 100 will make engine run leaner. Since my Skyline is currently running rich (usual symptoms such as soot on rear bar, poor fuel economy, etc), will Optimax 100 naturally cure the engine from running rich? You opinions appreciated

    • H2 (for cars) will never happen. It's not reasonable for any number of reasons. It's also not reasonable for almost all of the industrial uses that the fanbois say that it will be used for, again for a large number of reasons. There are some cases where it will be good. But, even those will be massively hampered by the economics. The only way that H2 can be economic is if we somehow manage to get from where we are to the other side of the economic-valley-of-death in which no-one can operate. You need there to be sufficient renewable generated electricity to be available so that it is effectively free. Once you are there, you can do whatever the hell you want and hang the efficiency. But until you get there, the ever diminishing value of electricity makes it harder and harder to encourage businesses to build the new generation capacity, and they will simply stop investing in generation projects. (I kinda think there needs to be just government money spent on building the required capacity in a non-commercial way, similar to how the first fossil fueled grids were built, as national-government owned utilities. And probably some nuclear in there to start. But this all should have started 10-15 years ago to avoid the chasm of death that we face right now). Synth fuels will be much more likely, but will only occur is there is at least some renewable H2 production, because you need H2 to do it. And you need stacks of free (or at least extraordinarily cheap) energy because assembling molecules back into fuels is exactly the opposite process to burning the fuel, and the reason we burn fuels is because there is so much energy squeezed into each molecule. So you're somewhat subject to the same economic valley of death problem as above anyway. That is unless people are willing to pay the current equivalent of $5 or $6 per litre of petrol-ish liquid fuels. Can you imagine it? The squealing at $2 now is bad enough.
    • This is so cool. Get a dashcam that records audio and hopefully you'll catch it.  Maybe there's a brand or some kind of markings on the back ? Are the pics hand drawn? I love it so much.
    • Hahaha yep, point(s) taken. I just like seeing different things and an EV in an R32 is pretty different. I'm not on the EV band wagon, I'm waiting for synthetic fuels or hydrogen personally. 
    • I mean it's probably likely that people overestimate their skills in dialling in a setup and noticing the changes. I had SK shocks and springs, and added heavier springs and got them revalved by Sydney Shocks to suit based upon what I told them I wanted the car to handle like. I got back a completely different feeling set of shocks, which probably (?) feel great on track but holy hell are they rough on tram tracks and the like. The shock dyno actually looks pretty similar to Shockworks (from what I can surmise from a screenshot of a youtube video - and my dyno printout...) Truth be told I doubt I'd be any faster or slower with either setup, or camber/castor combination. I also had whiteline eccentric castor bushes up front of my R34. I removed them and put in poly non-adjustable ones to soothe my OCD (nobody ever set the castor the same side to side, and it'd be near impossible to do) and be happy the wheel is centered in the well now for clearance reasons. Yes I wanted it to move 1mm 'back' :p I've effectively set my castor back to stock, negating all the benefits of that which is supposedly massive. I've probably also altered toe and camber in a negative (detrimental) way. I can't tell any difference steering the car.
