Asked by Oct 14, 2014 at 12:44 AM about the 2007 Jaguar X-TYPE Base

Question type: Car Customization

I was wondering how difficult it would be to convert / retrofit the engine to run a lower octane fuel, or even E85. I live in Michigan and E85 is the least expensive fuel, Premium is the most expensive.

You will NEVER EVER recover the conversion cost. Sell the Jaguar and buy a Hyundai.

It's possible but expensive, you have to change the compression (Pistons) & or the cylinder head cc combustion chamber volume to use lower octain fuel. Most cars hi-comp cars like this can get by on 89 octain. I use it in my turbo Fiat & Mini. It's good to use fuel injection cleaner once & awhile.

It might be cheaper to move to a state like Kentucky or Tennessee where the 90+ octain gas is under $3.00/gal.
