Not to get off topic, but what is the price of C16 or other race fuels these days?

I always run the cheapest stuff I can find and mix a quart of tranny fluid per 10 gallons of fuel to slow the burn so I won't hurt an engine. Giddy Up CowBoys

I just bought 10 gallons of 114 to boost up my octane after winter storage. It was $4.69/gallon. thats up about $1/gallon from a year ago.

It is kinda strange that alot of Nissan's Stuff requires High Octane .... My 02 SC Xterra ...we have several 240's .. 93,95,97 ..all require Premium ..

And my choice ..... ICEHOUSE ....

I use 93 but could use 89 since I lowered the boost. But I figure it's cheaper to pay the few extra pennies than to but an $8000 motor.

Compression, compression, compression. If you don't run a high compression engine, you don't need high octane. Octane prevents pre-ignition caused by compression. In a higher compression engine, the fuel/air may (will) explode under compression before the piston reaches the top of it's stroke. Imagine the stresses when that happens. That little "knock" you here is your piston being jammed back down on it's up-stroke. Not good! However, as many have stated above, if you don't need it, don't spend the money on it.
Hey Dave ....so what grade you run ? I found on merc site that after 1990 the recommend 87 for the 454's ....I am thinking thats mpi ? I can get 93 for 2.72 or 87 for 2.45 ...at .45/gal savings could add up ... its 2.99 at the marina now ....m

110 octane leaded (VP Red) is $5.75/gallon in my area. I'm using a 110/93 mix to keep it around 100-102. Long, peaceful, romantic cruises are a thing of the past!!!
