Whats the highest octane you will find at the servo, and the lowest you will find at the servo. In Victoria.

What is the usual amount?

Does it vary alot?

Is there any brand of LPG that has a consistently higher octane?

Is it the more butane added, the lower the octane? Are there any other factors?

thanks

LPG used to be 100 octane, but now, with all the crap that is mixed in with it, it can be anywhere. The usual rating is 98 octane, but I wouldn't trust it too much. I personally believe it is on the same par as unleaded, about 95

I had a 351 Cleveland that was built as a gas engine @100 octane. But I had to lower the compression as it kept on pinging.

I believe you can get bad batches of gas, as you can petrol. Again, use high volume servos.

afaik, no brand is better than another.

thanks for the info creature3. Its a bit dissapointing though. I was hoping the octane would be 100+. So I could run higher compression/boost in an LPG turbo. Oh well its better to know now than after your engine has melted away.

Yeha i always thought it was like 103 or higher. Agreed there are bad fuel batches at some places, but ive heard of people running high compression/heaps of ignition advance on straight gas motors.
