#1 of 5 Regular gas... by vettever Jul 09, 2009 (8:03 am)
Anyone use regular or mid grade? I had to put reg in my 02 ZO6 and it ran fine. Even hard accelration from 900 RPM in 6st, no lugging or pinging. Replies to this message: starrow68 (Jul 11, 2009 8:27 pm) dchalky (Sep 14, 2009 7:45 am)

Replying to: vettever (Jul 09, 2009 8:03 am) Ah, but the question is, why no pinging? The C5's and most newer cars have ECU's that register the grade of the fuel burning and when they get the news that the octane is down, they just detune the car to run with less zip. Not bad for the engine or anything. You just aren't getting the same performance you would get with 91 or higher grade. Then again, for fun you can add 100 octane unleaded at the track to top up the tank, about 1/4 tank to average up to 93 octane or 1/2 tank to get just past 95 octane, it does make a difference. Just make sure you never get to the leaded race gas, expensive to replace the cat's. Randy

Replying to: vettever (Jul 09, 2009 8:03 am) Actually, C5's cannot determine grade of fuel, whether it be E10, non-ethanol, 87,89,91 or 93 octane. What does happen is if engine knock sensors detect any knock, the ecm will resort to using a lower timing table, in effect, pulling timing until knock is gone. The ecm contains two timing tables. Every day driving and no knock, engine will use more agressive of the two tables. If engine identifies knock, it will default to lower table and actually start to learn and blend both low and high timing tables until max timing can be used without knock. Over time and with no knock, engine will try to return to using higher/more agressive timing tables.
#4 of 5 First Corvette by kentmagnuson Nov 30, 2009 (11:49 am)
Wife and recently took control of our first Corvette. Is a 2010 LT2 Coupe, Blade Silver, 6 speed manual with Callaway shift linkage, upgrade chrome wheels, all body-color attachments (door handles, trunk spoiler light) and grill, exhaust and side cove inserts of the screen. Beautiful setup by Harchelroad Motors, Imperial,NE. Thanks folks. Well done. We get great fuel mileage of 34mpg at 65mph and 25mpg at 80mph. Is as much fun to look at, for us, as to drive. We love the car. Takes some jockeying to get the seat comfy on driver side, being one with long legs. At any rate, this is huge fun for both of us. I hope many of you can recall your first...Vette.
