Nulon, STP. ect, add 7-8Ron points, so it should be around102-103 Ron.My car runs fine but is it safe to use and are there any pitfalls?Has anyone got any info with regard to octane boosters.Thanks.

Add directly to the tank prior to filling. Experiment with lower doses to establish the optimum treat rate to stop detonation. Use with each tank full.and http://www.nulon.com.au/products.php?produ..._Octane_BoosterIndicative RON increases:91.5 Unleaded +PSO=96.5 (5.0 RON increase)95 PULP +PSO=98.1 (3.1 RON increase)98 PULP +PSO=100.1 (2.1 RON increase)100 PULP +PSO=103.5 (3.5 RON increase)(When used at maximum recommended treat rate.)
smicky Go Pies!!! Legacy Donating Member 2,852 Member For: 18y 7m 17d Gender: Male Location: Vic Somewhere - Sometimes NSW Posted 27/11/08 03:49 PM Posted 27/11/08 03:49 PM (edited) I have run Oct Boost (Nulon Pro Boost) a number of times over the past 3 or so years, in both the Suby GT and once or twice in the F6...Without any special tune, and found that it does have a slight increase in response... (either it actually does have some positive effect, or its all in my head)!The Pro Boost is meant to give a higher PSO from memory on the back of the bottle is meant to give from 2-7 points and OBC 2-4 from memory... Price difference is about double for a bottle also... 15$ v's 30$ I think... again not sure havent used it for a while now...Last time I ran a full bottle of PSO with about 3/4 tank of 100oct fuel just to play on the weekend, and was sure it had some advantage...I had also spoken to 2 or 3 mechs/tuners, in the past who have said that fuel injected cars such as the GT had a OCT sensor (or something as such) built in therefore, would not require a tune to gain some advantage of the PSO or whatever form you buy... (obviously a tune to that mix would have a greater advantage)... As the car has a OCT sensor the engine management system can and will accommodate for the increase in OCT levels and act/calculate accordingly - hence as the fuel companies say you will get more KM's per tank..... As it effects your AFR.... However drive hard and it will have a higher usage level (I believe the story goes)...This is also why its is not such an issue if you do choose to run 95 in a 98 recommended fuel system, just as it is 'safe' to run E10 if you wish... (mind you some E10 has a higher OCT rating then 95 PUL also)....I am not personally a tuner, or mech, however this is what I have been told, and so far on the occasions I have used such products never had a problem... Having said that - I personally dont believe 30$ extra a tank just to raise the OCT by say 2 points is really worth it to be honest.... So up to you either way!When ive done it in the past its just to be a bit of a tool on a weekend and anything extra 100oct + the PSO is just to try and get that little bit more zoom zoom without a tune...

Iconic Bionic My engine bay is Bionic Legacy Donating Member 3,726 Member For: 20y 6m 15d Gender: Male Location: Freeways Posted 28/11/08 12:47 AM Posted 28/11/08 12:47 AM There is research that I will try and find that has found that most of the ocatne boosters tested caused a 7hp loss overall. However a few of us were in this pickle on the snowies cruse, after a long detour we had to fill up using 95ron but most of us had a bottle of octane boost. I added the bottle and left the car on the 98ron tune and it went like normal. I do believe that they raise the ocatne level, as in this cirumstance but I dont think they raise the horsepower in any way.A bottle now and then may also add some cleaning benefits to the fuel and injector system.I.B.
