Is it bad if the exhaust smells like gas? If so, then what seems to be the problem with my Isuzu Trooper? For best results, follow the recommended fuel or gas specifications by the manufacturer. Also, using fuel with greater octane ratings than what's recommended by the manufacturer isn't necessarily be better. Using lower-octane fuel or gas could also compromise the engine's optimum performance.
Some of the negative effects described by manufacturers include heavy metallic rapping, which could cause mechanical wear or damage. It's not advised for you to use a lower-octane gasoline or fuel than what's prescribed.

Your owner's manual would serve as your guide for the manufacturer's fuel requirements and recommendations. You should fill your tank and feed your engine with the recommended type of fuel, with the right octane number. What would happen if I use lower-octane gas/fuel on my Isuzu? What would be the effect? Also, would it be better to use fuel with greater octane than what's prescribed by the manufacturer? Before the symptoms turn worse, trace the root of the problem and fix this right away. The nasty odor from the exhaust could be accompanied by some performance problems. Other probable reasons for the pungent smell are a busted fuel pressure regulator and an engine that operates at a hotter temperature. If this is the case, then the converter has to be replaced to eliminate the odor and fix other relevant issues that come with this. The strong odor may surface because of a plugged converter. However, when the converter is broken or the filtering layers become defective, sulfur isn't converted into sulfur oxide, leading to the pungent rotten egg smell. Sulfur is typically transformed into sulfur oxide, which doesn't contain any odor. The rotten egg smell is from a compound known as hydrogen sulfide, coming from a small trace of sulfur in the fuel.
