Race Gas help

sbdavis1 · 10-19-2009, 09:55 PM

Hey guys I was curious as to how bad 100LL gas is compared to 100UL gas. The low lead is half the price locally. I know the low lead can clog cats etc. but i'm catless now and would love to pay $2.99/gallon vs. $6.99/gallon of the unleaded.

my mods are:
JB3 1.4
AR catless DP's
FMIC
Britalman Catback exhaust
DCI

can I run the Low Lead?

its funny how on the BMW forums everyone is so afraid of leaded race gas. when i raced talons/eclipses i ran race gas all year long not just on the track, never once ate up an 02 sensor.. if your going to only use it here and there for the track. save yourself an assload of money and get the leaded. i would kill for 2.99 race gas. its 7.99 for 100 unl in UT.
