87 octane in an 02 ZO6...

Howdy gang, haven't been here for a while but I just got to shout this out. Took a road trip from Fl. to Pa. and ran 87 octane. No problem, 1000 RPM, 6th gear, floored it and pull, pull, pull. No ping, absoulty no noticeable differance in performance. Gas mileage, 29.3 MPG. I've been feeding "Bad Booger" high test for 6 years and he's drinkin' the cheap stuff (like me) from now on.

Yeah, you can run 87, but you'll eventually get the ping, then all hell breaks loose. You know, I don't know if you can even hear it in a modern car. I'll keep feeding mine the good stuff. 120,000+ miles and ticking...and I'd like to keep it that way.

The std LS 1 engine can run 87 and if I'm not mistaken it's spelled out in the owners manual.

I run 89 in my LS3 and the computer adjusts to the octane in most cases.

I agree. I run only Chevron, Texaco or Shell and have 155k with no issues. I figure that saving $2/$4 a tank isn't worth it to me. Shoot, that's the price of an Egg McMuffin and a coffee.

I'm not sure you would hear pinging unless it is already a severe problem. These engines have knock sensors on them that will pull timing if pinging is detected. Power and fuel economy will normally be sacrificed by retarding the timing. So although you may not hear pinging while using lower octane gasoline, you really may not be doing you nor your engine any favors using it.

Is there any truth to it? Or is it just a way of marketing for the oil comanies to sell you the same product under two different labels and pay more for the exact same product?

Here's a link to what Tier 1 fuel is about and who provides it. It's been around since 1997.

Back in the day I would top off my chevy with Sunoco 260 when pulling in the the St. Pete Drag Strip, did it make a difference. I thought it did. I do know that at 25k mile my fuel gage became erratic and slugish. I switched to the Top Tier fuel based on a recommendation of a member on a dirrerent formum and have never had an issure since.

I often wonder what are the chances that the guys driving the tankers put the gasoline into the wrong tanks when they deliver at the stations. Or in some cases regular gasoline is deliberately put into the high test tank so the station owner makes more profit.
