101 Octane

[Steve Dallas]

I don't know for sure if this is still being sold (the post I read was from 2008), but a gas station in Auburn, WA apparently sells 101 octane.

I was doing a search to see if I could find any that sold 93 octane because most of the places here only sell 92.

I was, however, curious about the implications of using 101 octane in my 2SS.

Thoughts?

If you do, make sure it's unleaded.

I use the VP Unleaded 100 in my Camaro. It has a GM Performance Parts Crate engine that makes 14 pounds of boost.

Depending on your tune too much octane can hurt power. It shouldn't hurt the car but because it has a slower burn rate there might not be any advantage.

Mixing gives different results with the different fuels. It's not like you can mis 92 and 101 50/50 and end up with 96.5 octane. It usually ends up being about 93 to 94.

Really from what I have seen with these cars is that the stock tune works well with 92 octane.

Good luck!

Yes this is a true statement.The 76 Union station on Auburn Way
sells Trick Racing 101 unleaded at the pump. I used it ocassionally in my previous car,an'06 Cobalt SS/SC with mods.BTW that car is on the lot across the street from there at Auburn Chevrolet where I trade for the Camaro.They also have the rest of the Trick Racing gas line available for purchase.

Robin is right on. Anything higher than what the compression ratio, timing, and of course if forced induction is a waste of$. It won't hurt the car, but your power will be down as the higher the octane, the slower the combustion.

High octane fuels are used where we need to control the explosion to prevent detonation and melted pistons due to high compression ratios. 93 is good to 11:1 in most cars equipped with knock sensors & PCM/ECM to controll A/F & timing functions.

With a forced induction application, higher octane can be beneficial when running high boost. On our race motors we target 13.5 to 14:1 and need 116 or better for 900-1000 hp N/A.

at 6.99 a gallon here locally, I'm gonna stick with the 93 octane !

One of the reasons I'm asking this is because I've been reading about the pull fuse issue, and how the car can get set for 87 octane instead of the higher.

My seat of the pants gauge seems to think that the power my car is doing is just fine. However, it's also been a few years since I've driven anything like this as my last few cars have been the Impala and Lumina. Last muscle car I drove was my 73 Dodge Charger SE with a 440 Magnum, and that was back in the 80's. And, it's pretty tough to compare it with a motorcycle as well. So, call me Donnie as I have no frame of reference here.

Anyways, I've been looking for 93 octane here in Seattle just so I could do the fuse pull and ease my mind on that issue, but all I've been able to find is 92...which should work ok...but I also wouldn't mind putting in 93 if I could find it.
