If you were to syphon a quart of gas out of your tank and take it to any bulk fuel plant, they could test it and tell you for sure what the octane rating is.

I work in the fuel industry and believe me, the suppliers do take complaints like this seriously. At the very least, the owner of the station would recieve a warning to train his attendants better.

My 2 (cdn) cents worth.


*edot* Just a thought here, since mistakes do happen.......... someone could have filled the premium tank with regular and your complaint may just save someone else from the same problems.
Our tanks have an anti-syphon valve that prohibits syphoning gas. I'm not 100% sure when they started but I think Bill'* has it.

But you make a good point.

It'* actually a screen IIRC. And yes, it defeated me last year at the dragstrip.

It matters not. This is a low-profit budget station, and there'* really nothing I can do. I appreciate the ideas, but I'd rather focus on the path forward with the engine at this point.

For the last two years, my goal was to push this engine to the breaking point. The good news is that I couldn't. It took someone else'* mistake and my oversight to make it happen.

Thats very scary that such a thing could happen to an engine like that.

Good luck on the replacement process.

I may be commenting pretty late into this, but I have got to have clarified the KR issue. Is it that you had a knock that busted a piston head? I read through the entire thread, but I'm not entirely sure yet.

He was running knock free and a gas station attendant who wasn't paying attention put 87 octane in his tank instead of his 92. And without Bill noticing he drove like normal and popped a piston.

Well, is it the knocking that broke the piston?

Think about a large hard pointed hammer hitting the piston on its way up instead of a soft flat one hitting it on the way down.

That'* a very strange way to have an engine go. I'm really sorry about that.
