A lot depends where you are in regard to altitude, and how well your ignition timing is adjusted.. regular should do just fine, unless you have a high compression engine (above 10 to 1) or in plain English 140lbs per square inch, then a premium
octane fuel might be the answer.first try octane boosters,then check your ignition timing(6degrees to 8 degrees advanced timing )
don't forget to check the plugs coloring , too dark means too rich, too light gray means to lean, and somewhere in between is good! I have noticed good quality gasoline can make a difference, and if you can not afford that type of gas try additives (octane oriented).

my 98 with a 5.9L recommends premium gas only but depending on your engine you should be able to run regular
