So, with Gas prices hitting $6+ per gallon in Oz for low grade unleaded, it's getting a fair bit more costly per month. Premium is now $6.80 per gallon!

I drive the Cobra as a DD and it gets the odd run in boost, but mostly just potters along. If I take it out on the weekend it might get more of a workout but for 95% of the time, it just cruises.

I know we don't have knock sensors in our cars so I want to know if it's safe to run normal unleaded if I'm not into boost all the time?

Remember that our grades of unleaded are inferior to yours but in comparison, our premium is 91 Octane, and we have 89, and 87. We also now have the 10% ethanol blends creeping in which supposedly bring the base fuel up to 89-90.

What can I run??

Thanks,
Oz

Your car takes premium, I think you would be taking
a huge risk. I run 92 with 10% ethanol, cause that's all we got.
Tuned for 91, I get 10 MPG, Ya, it sucks, but I love my car.
Get a beater, but don't run 87.

 

[OZ Dude]

Yeah, just wasn't sure if I could run the 10% ethanol blends or not. They peg the Octane about the same as our "mid level" fuel and it runs on that quite well.

Can you use the E10 in a Termi?? You don't have any problems with it??

Thanks,
Oz

One has to wonder if threads like this will become more commonplace if the price of gas here climbs to near $6.00 a gallon. Sure would hurt the future of muscle cars. At least the V8 variety. :-(

Too risky in my opinion. .80 X 13 gallons is a $12.40 difference each fill up and a new motor is well over that. Stick to the good stuff, my man.

The ongoing issue here is that the price is climbing weekly. We've already been told to expect $7 per gallon for 87 octane by next week. That'll make premium unleaded up to $7.50 per gallon.

$100 to fill up a Cobra anyone??

Welcome to the brave new world :bash:

You can now get a knock sensor system for our cars:

I believe that a simple tune for you car will allow you to run the lower grade octanes. All they should have to do is retard timing and maybe a couple of other things. I live in Colorado and we have 85, 87, and 91, all with E10. You can't buy any gas from any station here that isn't E10.

Bad idea to run cheap gas. Maybe if the car is bone stock you could get away with a lower octane only tune. Other than that I'd stay with the higher octane

 

[OZ Dude]

Ugh, gas went up 20 cents per LITER today and they say there's more to come. Can you imagine driving in to a gas station only to see the price is 80cents per gallon more than yesterday??

I'm surprised all your fuels have E10 over there. We only have it in limited quantities and then it's only the lower grade fuel. Mobil are the exception, they market their blend as a mid grade.

Tha knock sensor sounds like a good idea but by the time I pay for that, and a tuner, I may as well buy better gas :shrug:

Damn, it looks like things are really getting bad for you down there, Tony :nonono:

Did prices just start to rise?

For me it's gone up $1/gallon since the beginning of the year, which is bad but not intolerable...

why do people even consider this....do ya'll understand how a boosted engine works?

 

[69sta03cobradan]

Supercharger=stay with high octane fuel or the engine will be making lots of strange noises and may even stop working all together... is the savings per tank worth the 7 to 9 k for a new engine (someone correct me if this figure is inaccurate).

Not really. Can you explain how a boosted engine needs higher octane over a Normally aspirated engine?

Maybe you need to fill up a few 55 gal barrels and store them in your garage to hedge against future spikes. Just keep them safely away from the gas water heater and/or gas furnace.

Funny story, a friend's wife threw him out of the house and sued him for divorce. He was getting his stuff out of the house, which included the clothes washer/dryer. When pulling the washer away from the garage wall, he found a large wasp nest, so he threw some gas on it to kill the buggers. The gas soaked through (under) the wall to the gas water heater behind the wall. The gas fumes were ignited by the flame (major bummer). He got the fire put out, but not before burning down half the garage. When she got home, she was pissed. Unintended consequences!

I only run 93 in my car,Its only $4.05 here, I use to haul gas from the refinery to the stations here in TN. about a year ago and my boss told me that ethinol raises the octane levels, My exboss has been in the buisness a long time and he talks to the station managers daily so i think he knows what hes talking about. For instance when we loaded for shell we would put the same gas in the regulare tank as the midgrade tank becouse it raised 87 oct. to 89. You might want to look into this. Good luck man
