1) Engineers at Ford have designed the motor to use higher octane.
2) It is supposed Lincoln owners can easily afford the higher cost.

What type of gas should I put in a 1998 Lincoln Naviator?


Since your vehicle is a bit older, it could probably use a higher octane gas for at least one tank full. This will burn hotter and clean out some of the crud left from any lower octane gas. I would use the highest octane available for regular vehicles, not racing gas though. If you find the higher octane too pricey to use all the time your car should be fine on the mid octane gas.

What grade gas should be used ?


You should always use premium fuel on the high conmpression V8 engine. Cheaper fuel can cause a PING, and possible engine damage. 87 octane is definitely not recommended at any time, but sometimes you can get by with 89 for a small period of time.

Gas mileage and power will both be down with lower octane fuel, so do not use it all the time.

Developing a ping... not bad gas, low miles


It may not be bad gas, but it could be the wrong octane rating for that engine. Check your owner's manual and see what octane is recommended for that engine. If you're running 87 octane and it requires 91 or higher octane, then you need to be running the higher octane fuel. By running lower octane fuel in an engine that requires higher octane, your getting pre-ignition, the knocking sound you hear. What's happening is that as the piston moves up on the compression stroke, the gas/air mixture is compressing and as the pressure goes up, so does the temperature of that mixture. It's possible that temperature can get so hot that the gas/air mixture ignites from the high temperature and not from the spark plug. Higher octane fuel will help this since higher octane fuel is harder to ignite. I say try running some 92 or higher octane fuel in your car and see if you still hear the knocking.

My 2001 lincoln ls starts hard when the engine is cold, wondering why


One issue is octane. You must use the specified octane, according to Ford. Lower octane is more explosive, many owners were using higher octane and generating yoru complaint.

What type of gas should i use in a 2005 lincoln navigator?


HI. i recommend using the premium in this vehicle. This will ensure optimal performance. The fuel system will accept the regular blend as well but, this is not what this vehicle was engineered for. the regular blends octane level is not sufficient for optimal acceleration and overall performance.

Please rate and god bless:)
