A dollar or two saved at the pump is not worth the potential long-term damage down the road.
Point taken but it'* more like $7 per tank at 10 cents per litre more with a 70 litre tank. If it were just $1, no one would use reg unleaded. With a lot of driving it adds up to approx $700 p[er year for me so if I could get away with saving that money I was going to try. No biggy though. Thanks

If you drive 15,0000 Miles a year

and average 25MPG. (mostly a highway car)

that is 600 gallons of gas.

87 is around $2.85 here and Premium is around $3.00

That is 15 cents a gallon on 600 gallons.

That is $90 a year.


Engine Rebuild due to massive KR problem - $1500+

But If I were you I would really use atleast 91.
LOL You would think 8 points meant 8 points, that'* quite the false statement then.

You're reading too far into it.

If it says it increases your octane 8 points then it will take your 87 octane and make it 87.8 octane. The gas can vary in octane more than that anyways so the stuff is pretty much useless.

I have heard auto experts both say no matter and others like many here say you must use it.
Those auto experts are probably talking about cars that don't require premium. Some people think it will help those cars and in most conditions it will not. Now if your car requires premium, the manufacturer isn't going to say it requires premium for the hell of it. The car needs premium.

On the octane needed for a supercharger. The reason behind the octane requirement is the predetonation or pinging. The knock sensor in the engine is supposed to pick this up and retard the timing (cutting power) until the pinging is reduced to a tolerable level. With that said.. a sensor can fail and larger problems can develop.

The required octane is designed to keep the pinging to a minimum to begin with, keeping the car running better.

This thread is a possible issue from lower octane fuel. Note the pictures of parts with holes in them.

You know I have been trying to locate a station in So. Cal that has Octane rating higher than 92. I have only found one station at 92 only. However I do know of stations with 105 and 110 and I don't need this for my daily driver. Just 93. Any Ideas anyone?

Running 91-92 Scan the car and look for KR..

Work with it from there. Maybe upsize the pulley to compensate.
