style="text-indent:25px">在工程車用油中，壓縮比通常在7.5～8.0應(yīng)選用90號車用汽油；壓縮比在8.0～8.5應(yīng)選用90號～93號車用汽油；壓縮比在8.5～9.5應(yīng)選用93號～95號車用汽油；壓縮比在9.5～10應(yīng)選用95號～97號車用汽油。一般可以在汽車說明書中查到壓縮比，除說明書以外，有的車輛生產(chǎn)廠也會在油箱蓋內(nèi)側(cè)標(biāo)注推薦使用的燃油標(biāo)號。車主應(yīng)嚴格按發(fā)動機不同的壓縮比，選用相應(yīng)標(biāo)號的車用汽油，才能使發(fā)動機發(fā)揮出較佳的效能。如使用比規(guī)定要求低號數(shù)的無鉛汽油，發(fā)動機將出現(xiàn)爆震現(xiàn)象。一般在急加速及爬坡時出現(xiàn)爆震現(xiàn)象，如果由于汽油標(biāo)號低，使發(fā)動機長期出現(xiàn)爆震，將會損壞發(fā)動機，甚至打壞活塞、缸體等。</p><p
