Octane Boosters/ Fuel Additives

[MK7GTiPP]

What are everybody's thoughts on adding octane boosters (the kind you get at a gas station)?

My thought is it's a waste of money. Put in 91 or 93 (if 91 is not available like in my area) and you are fine. Fuel additives are a different story and may or may not be valuable depending on the age of the car and the detergents in the gas you use.

Based on your mod list they would be a waste.

I tried royal purple with 92 octane vs. 93 octane. The royal purple should have raised it to 95 octane based on their claims. I datalogged with a JB4 and saw better timing, less corrections and more boost on the 93. The octane booster is snake oil. Use a few gallons of e85 instead. Won't really do much in a stock tune though

i run torco and royal purple octane booster. both feel a little better with 93.

This is a good answer. Glad you went out of the way to do the research.

Just curious. Is there any benefit to running 93 + some e85 on a stage 1 or 2

Agree 100%. Don't waste your money on octane boosters/fuel additives. Just throw in a couple of gallons of E85 the next time you fill up.

problem with e85 is it can change afr. i ran torco and 93 on my 15 gt mustang and was running up to 31 degrees timing advance.

Without more boost or compression the need is really not there. Personally I would just run the 91 or 93. I run 93 even though I have access to shell 91. I found it to run a bit smoother.

I logged a ton of runs with VP Racing Octanium for other platforms. Turns 10 gallons of 93 into 101 octane. Legit non corn alternative.

Where can I find E85? I have never seen it at a gas station before..

Looks like there a bunch near you in Cincinnati.

Holy smokes, thanks man!

Okay, thanks TwinDad for that test. So octane boosters are a definite no-go. What about adding a gallon or so of E85? I saw some conflicting responses from you guys..
