I bought Shell gas first time in 22 years.
What to expect?

 

Aliphatic hydrocarbons.

 

The more you drive the more you will need.

 

Other than minor differences in mileage compared to other gas (probably more related to subtle differences in driving style/temperature/road conditions), likely nothing.

 

Once you have used a tank or two give us your thoughts?

 

Internal combustion.....

 

For your first post....thats all you got EH!!!!

 

Well you will actually feel throttle response more sensitive and when floored you will benefit from up to 30% hp increase! C'om it is only gasoline man!!!

 

Sorry, couldnt help myself.

 

I like it.
The car warms up way faster. There is more power and the engine runs smoother. The acceleration is definitely different as it is even through rpms. I am used to esso where at low rpms I was getting more power but at 6000 it was stalling.
With shell it is slower at low rpms but it becomes constant later and the power is even to 6400.
