Probably, yes. Gasoline comes with different octane ratings because some engines require a higher octane to prevent pre-ignition ("pinging" under acceleration or on hills). Check your owner's manual. Also, you can experiment with lower-octane (and therefore less expensive) gasoline. If you do not experience pinging with 87 octane gas, then that is all you need.(Technically, a higher-octane gas burns slower than lesser-octane gas, but that is beyond the scope of this question.)
65% of 87 and 35% 93 to make 89 octane gas
That depends on what the car was designed to run on. If it was meant to run on 87 octane, using 89 octane can make the mileage worse.
always run 93oct in dirtbikes, this makes your bike good on gas and 5 mph faster.
87 octane is sufficient.
it will only if your car requires 89. If your car is designed for 87, then 89 will provide no benefit.
87 Octane providing that it does not "ping" excessively - if it does use an 89 Octane
Try 87 Octane, if it does not "ping" excessively you should be OK, If it does "ping" try 89 Octane
87 Octane providing that is does not "ping" excessively - if so go to an 89 Octane
it's a little better than 87 octane but not really high test gas, 91 and 93 octane is the high test.
All V6 engines and the 5.7 Liter V8 use Regular Unleaded 87 octane. The 6.4 Liter V8 requires 89 octane premium.
Depends on what type engine. the 2.7 L and 3.5 L are made for 87 octane fuel but can use 89 and 91. The 5.7 L can take 87 octane or 89 octane but i would use 89 for it. if i had the 6.1 hemi i would use the 91 octane cause it is a more consistent fuel.
Try 87 Octane if it does not ping excessively should be ok - if it does ping try 89 Octane
