What gas should you burn for a Lincoln Navigator?

Answer 1

For ALL vehicles, Use the cheapest gas your car will run fine on. Usually the factory will give A pretty good indication of the grade of gas for the engine. Usually high performance vehicles need A higher octane than average cars. This is because High perf. engines generally have higher compression ratios than others. A little about gas grading: The 'Octane' rating for gas is quite often misunderstood, The higher the number the more RESISTANT the fuel is to burn. Most people think that 102 octane (racing fuel) is highly explosive, actually it takes conciderably more energy to ignite it that regular pump gas.
