Octane Booster...Safe one to use with 02 sensors? - GT-R Register - Official Nissan Skyline and GTR Owners Club forum

Sub Boy · 7th July 2009, 05:20 AM

I have noticed when doing a couple of track days that the knock readings get up there when I'm thrashing it, saw one reach 105 which gave me a scare.

Is there a octane booster that I can put in to protect the engine a bit more on track days, that won't hurt the 02 sensors....And yes I always use Mobil 98 (only 98 fuel available in ChCh)

Use the search, theres a massive thread about octane boosters.

Octane Booster

kismetcapitan · 7th July 2009, 08:19 AM

toluene. loads of it. 40 liters in a tank, top off the balance with premium 98 RON or better. and I run without O2 sensors...I finally found that the car was easier to map without those damned things kicking in and giving THEIR "narrowminded" opinion about fueling (oh lord, do I crack myself up...I'll get me coat)

Cheers...But I'll pass on the Toluene, I find the car runs much better with the 02s still running.

Octane boosters are rubbish!!!!

Consider fitting a Water/Methanol injection kit on the car for track days.

Time is short at the moment, I have a track day this weekend. This is just a quick fix at the moment.

i know that NOS do a 6-point octane booster which has no LRP additives, and they state that it is safe for CATS and lambda sensors. not sure where you would buy them in the NZ but i'm sure a simple search of your local suppliers/websites (google.co.nz??) would yield some results for it.

That should be a short-term solution.

But as NISFAN said, a long-term solution is water-methanol. You can then play around with the methanol mixes so that you can achieve your own desired octane levels.

Cheers Guys, I will find out whats available in NZ, the three to go for look like NOS, Nulon, and NU.

....I will also have a look at Water Meth...But I think the main problem is the factory knock sensors and P-FC are average, Might have to invest in a NZ Made Knock-Link.

You can get E85 from Mobil for around NZ$3.30/litre :P
