Regular Unleaded is just fine.
The correct octane fuel for a 1998 Subaru Legacy is RON98. This is the right octane to be used based on this car's engine for best performance.
a 1999 legacy can drive on both 95 as 98 octane fuel, 98 is slightly more expensive, but still preferred by most legacy owners, since 98 is more efficient and slightly increases performance.
Unleaded; minimum 87 octane for normally aspirated engine

All Subaru SVX engines were designed to run on premium fuel of 93 octane.
The best answer is in your owner's manual. You can be sure the owner's manual will give correct information. Different engines require different octane levels. If you do not have an owner's manual, Subaru provides free access to .pdf files on their Web site. http://www.subaru.com/owners/resource-center/owners-manuals/search.html What it says is 87 AKI or higher for non-turbo four and 91 AKI or higher for turbo or six cylinder engines. There are additional recommendations in the manual and you should read them to see if they apply to your location and fuels available. If you are seeking a gasoline brand recommendation rather than recommended octane, everyone has an opinion and they are of little value.
Not really. Fill up with the "correct" octane when you run some fuel out of your ride.
Try 87 Octane, if it does not "ping" excessively you should be OK
Trust me and just use regular. subaru engines are an 87 octane rating and buying a higher rating will do nothing except waste ur money and is actually bad for any fuel injected engines that are an 87 octane rating. i could be wrong but but higher octane rated gas is for higher compressed engines, like muscle cars with big heads and such. Now if you have an older CARBURator engine, then a higher rating could be better if the engine is old and not running with the soul it used too! but this does not apply with fuel injected engines so follow your owners manual specs and just get a tune up or something jeez.
is it right 92
Most use 87 octane but some use 89 or 91 octane. The correct grade is listed in your owners manual.
