Only if you experience excessive "pinging" at acceleration
Perhaps you need to try a higher octane fuel i.e. 89
A 3vze engine will take anywhere from regular 87 octane, up to 100 octane race gas. However what is your purpose to using higher or lower octane, Using regular, plus, or premium will work well. however higher mile engines would prefer 91 octane!
My 2000 uses 87/unleaded in the manual

No reason to use it. It does not increase power output. Mowers are designed to run on regular octane gas, and do not need higher octane numbers.
need to bleed the lines
I need to change the fuse on the horn and hazzard lights on 1990 toyota pickup, what amp should I use?
yes
the 318 V8 uses 87 octane 383 2 bbl. uses 87 octane 383 4 bbl. uses 93 octane or higher 440 4 bbl or 6-pack uses 93 octane or higher 426 hemi uses 93 octane or higher If you still have the stock heads on the engine and haven't had hardened valve seats put in them you need to use a lead additive in your gas.

You can use whatever octane you want, generally you shouldn't have to go to higher octane unless your car requires it. If your decidin to go higher because you feel a better power increase this is a sign you need tune up
If you listen to the engine under load conditions and it rattles or pings then you should use a higher octane fuel but you should research more on this through these pages to determine the need for a higher octane value before you tear something up.
