Is BP hi-test still the old AMOCO white?

[Rondor]

Based on several threads here this ? comes to mind as it was stated that they had better performance using BP. In the sixties Amoco white was one of the better fuel for muscle cars. I even payed $.38 a gallon for it

Amoco 'White' in the 60's-70's was 100+ octane.

I wonder what the rating would be by todays mearsurements. Now they take the average of two methods, one is Research method and I forgot the other one. I will edit after I look it up.

It is Motor Octane Number.

More info. In Nebraska they add 10% alcohol to 91 and 89 octane. That makes my 252 HP motor like 200 HP. I do not even have the coice of trying out 89 octane, I need the power.

Here is what Wikipedia says "Where the octane number is raised by blending in ethanol, energy content per volume is reduced". It is like not pressing the acellerater all the way to the floor. So when you pass a car on a 2 lane road you may not have the power you think you have

Man, HKS, you really hit it on the spot. Now, because of federal regs, the distributor does not have to tell you how much ethanol is in the gas over a certain amount. I have been running Phillips 66 since I got the T-Bird and over the winter developed a check engine light. Lean mixture, left and right bank. The other day I switched to BP, no light. Interesting.

Here in OK, Phillips 66 is one of the places I can typically find ethanol free gas. Must be all that corn they grow in KS.

I understand from a friend in the business, every company allows a percentage of non branded gasoline to be mixed with the company's blend. Some use more than others. It increases profitability for different locations. Apparently, the 66 business here is using the max allowed by Phillips/Conoco. I am using Amoco for now.

Re: Is BP hi-test still the old AMOCO white? and 89 octane

Does anyone know when the engine knock sensor retards the spark due to low octane fuel, and if you put 91 octane back in the tank, how soon will the engine detect and return to the correct spark advance? Or, do you need to disconnect the battery for 10 minutes for it to reset to normal?

Do you suppose that the computer ocasionaly advances to spark and listens for knocking? This would mean that the knok sensor needs to to tell the computer to advance every so often to find out when it is safe to to go back to normal advance. So, some engine damage is tolerable?

P.S. Hasn't anyone else wondered about this?

The engine is constatently monitoring for fule octane rating and knock. The optimum operation of an engine is very near the point at with knock occurs. In theory, the engine adapts timing and other factors to whatever octane level it senses in the fuel and make necessary performance adjustments. It also monitors knock and then retards the timing as required to avoid knock.
Ford recommends 91 octane for best performance but I think the engine will operate just fine on 89 because it can adapt to the the 89 (no less). However, performance (HP, milage, etc) will suffer if you use anything less than 91.

Dont they grow more Wheat in Kansas and corn in Nebraska?
