-- Yeah, but that's a valid question though..... As a creature of habit I use 93 because everything else I drive uses some form of Forced Induction. Being Naturally Aspirated would make the compression ratio dictate the required octane rating...... so probably some simple goo goo ling would answer that.........4 points worse than 93?
The only "Noticable" difference is going to be your engine possibly running smoother on higher octane fuel but it's not going to make any more power just because you put in some 110 octane. As for 110 Octane, lets hope your not running leaded racing fuel or avgas at a 30% mixture...From personal experience in my LP640 (Yes, I know the OP has a Gallardo) blending 110 octane with 92 octane (max I can find in my State, plus we have 10% Ethanol) makes a noticeable difference in power. You can blend it however you choose....5 gallons of 110 to 15 gallons of 92 for example would equal about 97 octane.
You don't need to waste time trying to convince me because just adding higher octane fuel doesn't make more power all things being equal. And I don't need to re-read your post, I read it correctly the first time.Re-read my post. Not leaded. And your wrong but I have no desire to waste time trying to convince you.
Yes these are good facts on every day cars and it gives you an idea. Your driving a race car actually with precise parts that are not cheap. You can use cheap gas but over the long haul it will eat things. Its called detonation and what do you think that detonation is doing. When you put a m80 on the ground what happens. It takes part of what it was in contact with away or makes a big hole. Do that a thousand times a million times. Yes most car computers will take timing away when knock is detected but barely. When you take away timing you lose horsepower. It can only take away so much. If anyone wants to see pics of what cheap gas does I have some pics of two different cars. I have more but can't remember where they are. Racing fuel is good for tuned cars that are modified to use it but stock cars will barely make a difference. Its a waste of money in my opinion. Do what it says in the manual or on the gas door.To anyone who feels like the entire design of your engine revolved around limiting it to 93 octane (Really? It's a factor of course but not the key component) then you'll probably dismiss this article and others like it as well. Is Premium Gas Worth It? We Test High Octane on 4 Popular Vehicles Why not just try the higher octane and see if you can tell a difference? If it doesn't affect your performance for the better you're only out the cost of the pricier fuel. This thread has more lovers and haters for you to consider.
The butt dyno is lying on this one. Sorry guys. As far as the tires "spinning" probably about 10-20 degrees cooler, if its cool outside my car hazes first pretty good, if its hot it hooks and goes. Also maybe the morning you put the 105 in it was colder out. Colder air is more dense and...www.lamborghini-talk.com
