Type of Fuel Question

[rhino 2]

If the computer can combine air , fuel and timing in the right combination, octane won’t matter . BTW , a bottle of injector cleaner might be cheaper in the long run than high test . Ya only need a little at each fill up .

To some extent......Exactly......

Not so sure about that, Rhino. Compression is the great variable. Even if you could get those variables under control of a computer, could an engine run (produce power) with an octane of 50?

There’s a limit to everything….But hypothetically if only 50 octane were available..Then all compression ratios have to be adjusted to run on it..The model T ran on 50 octane in 1908.

And no I’m not an engineer’ I learned stuff mostly by doing and not making the same mistake twice….
