4 gallons of 109 Octane Gas for My E55 = WIN! :)
If you never fed your, "Beast" 109 octane gas, do it once and you will be amazed!
Tomorrow I'll do a 0-150MPH romp in .6 of a mile show you the ferocity this unleashes.
Happy New Year Everyone!

VP Racing says this about MS109 though
http://www.vpracingfuels.com/vp-racing-fuels.html
"MotorSport 109™
In engines that can run on pump gas, MS109 is a direct replacement that produces more power than any other unleaded fuel - up to 5% more than premium unleaded. Recommended for applications with up to 25 lbs of boost and naturally aspirated engines with CRs up to 15:1. Compared to other unleaded fuels, MS109 offers better detonation protection as well. Excellent in crate engine applications."
Not sure how they are coming up with this but I am curious about the claims. It's unleaded so shouldn't hurt anything to run this. I could see the computer getting used to not having to pull timing (if it is pulling it) then regular 92/93 going back in and causing a lil knock before the computer compensates.
• Motor Octane 101
• Research Octane: 109
• R+M/2: 105
Basically I think the extra power is mostly a placebo effect, but probably won't hurt anything. Smells nice though.

I am sure the car feels better because the ECU tunes the knock threshold up and you are actually making more power... Porsche ECU and BMW ECU are very good at adapting to gas... I am sure Benz is the same...
The Best of Mercedes & AMG
In AZ the highest we can get is 91 so with 4 gallons of 109 it probablly mixes to 93 maybe 95?
It does feel MUCH stronger for what it's worth and I'll try and do a recorded 0-150 MPH blast to show you.
Thanks as always.

I now use that little bottle ANYTIME I am racing my S600 just for a little added insurance.
As far as this motor was concerned, BOTH made the same power. Neither EVER hurt my 02 sensors, and both had a lovely smell with No cats.
Hence I believe it 104 octane booster, take it for what its worth.



smells soooooo good.
