Premium unleaded is recommended for the Lincoln Mark series. Apparently you can use regular but I've heard/read of reduced performance and mileage.
I've always used premium in my 93 Mark VIII and it runs very smoothly. For me, the 20 cents/gallon price difference isn't worth risking extra wear and tear to the engine.
Unleaded fuel only , octane 87 or higher ( according to the 1997 Lincoln Town Car Owner Guide )
What kind of companies use natural gas in California?
unleaded
You CAN use regular unledaded gas in the Mark VIII. However, the performace will suffer, as will the gas mileage. When you think about the fact that premium unleaded is normally about 20 cents a gallon higher than regular unleaded, you are going to be out less than four more dollars if you fill an empty Mark VIII tank with premium rather than unleaded. The loss in gas mileage using the regular unleaded would cost more than this in the long run.
16 to 18 cty, 20 to 24 hwy, also factor, if your tires are properlly inflated, how many passengers you have, what the weather is like, and what kind of fuel you use. If your Lincoln recommends 91 octane, use it, using less octane gasoline may reduce gas mileage and engine performance.
