Octane Booster
Guys, as I'm stuck with 93oct fuel - Shell V Power, the quality of which varies from station to station, I was thinking of using Octane booster on a regular basis as its much cheaper than buying barrels of E85
Anyone used Royal Purple Max-Boost Octane Booster its said to be safe for O2 sensors and Cats? |

Octane booster isn't close to E85. I personally would buy a barrel and have fun.

Its a pain in the butt to constantly buy barrells, plus they are expensive as well. I'm asking if anyone tried a good inexpensive octane booster and noticed any benefits, such as using the Royal Purple Max-Boost? |

I have not used Octane boosters but I would be very surprised if you saw any benefit from them unless you are putting in gallons at a time. At that point a barrel of E would be way more beneficial.
It might seems like a pain at first but well worth it to just buy a large barrel of Ethanol.

(as you already know Saif cause we talked about that on the log thread, but just for the thread)
I tested a few, but it depends what you say by inexpensive or expensive. The one that worked the best on mine, is the Octanium from VP Racing (i only tested the Unleaded version cause i was still running secondary cats at this time) and it costed around 27EUR per bottle. (I used one per tank, sometime more because it happened that i refilled the tank at half tank with a new bottle + a new gas filling) By worked the best, i mean that with 91oct+1bottle, i was able to run 93oct map without any correction while without octane booster i was using the 91oct with the straight 91 and getting corrections (sometimes lot of). I also recorded my best times (on logs) with octane booster. Other octane booster i tested were in the same price range or a bit cheaper around 20-25EUR(Mecatech TC2 safe for cats, and Bardahl unsafe for cats), helped a lot for timing corrections too. I believe a big barrel of E85 (like 54 gallons for 500/600$ online) could be more or less the same price overrall if you just add 3 gallons or something just to raise a bit the octane and get rid of corrections on regular fuels maps 91/93, but it's not as convenient i imagine ? You have to have a place to store this barrel and probably a pump system to poor it in your tank, or to put it in a jerrycan.

Get Boostane, its better. I use a tiny but each tank and it allows me to run the 95OCT tune filling with 94 Oct. I find it much easier then running e85

54 gallons of it would cost about ~ £850 Just want to reduce some of the timing corrections due to stations with crap fuel quality and that's on 93oct V Power Shell. Thanks thats what I wanted to know, Is there any harmful side effects to long term usage of the Octane boosters said to be safe? |

Water/meth injection if you're absolutely needing to satisfy the craving to squeeze every last drop from your setup. You said you were gonna want to run it regularly, I went down this road years ago being on ACN91 and decided to stop and settle down. Be happy with what I have now, I'm not tracking/racing etc. The purpose of my car is to be a car not a speedship racer so I stopped. You will foul the plugs up for sure and longer term could screw up injectors and other things, your exhaust will turn orange etc.
Another alternative would be to mix in 100+ octane racing fuel.

i think once a month should be fine to use, as long as you go through 2-3 tanks of gas. Again, take it with a grain of salt.

Not after squeezing every last drop of power, lol. I just want consistency in terms of timing corrections. I filled up at a station not too far from where I live with Shell V power 93oct fuel, did a log and tonnes of timing corrections across multiple cylinders. Filled up at the station near my house with the same Shell V power 93oct fuel and only 1 or 2 minor corrections. This is irritating, to be at the mercy of stations. Problem with Race fuel is its expensive and comes in Barrels at about 4 x price of 93oct Shell V Power per litre. Last edited by Saif2018; 07-08-2021 at 03:48 PM.. |

lol no! I did that when I was on OTS, could definitely feel a power deficit, especially mid to top end. I'm on a custom map at the moment and it's mapped on 93oct fuel, I could ask the tuner to do a 91oct map, but that's a last resort, would prefer not to.

Boostane has charts that describe how much to use to achieve a desired result: https://boostane.com/about-boostane/...-mixing-chart/
My tuner recommended Boostane if I wanted to run more than the 91oct we have available here in CA.

So they said i had to put octane booster, that it will be safer, so before i got MHD, i run the car for extended period at each tank fill (during a 1 year at least) with octane booster (i was running the mecatech TC2 that is rated safe for cats) and did not have problem with plugs or something else. No corrections with the octane booster (or almost no corrections) vs corrections, or lots of corrections without... I stopped it using it since i have now the possibility to flash the 91oct of MHD, and buying a bottle of octane booster for each of my tank filling is a bit expensive at long term and is not convenient but i miss a bit the power of the 93oct map, as you said, you can definitely feel a difference. Crappy gas is a scourge...

How bad are your timing corrections?
Some corrections are fine as long as they are not super high.
