Would having the wrong octane make a tapping noise in the motor and make the check engine light come on?

Not sure about the check engine light; however, several of the Hondas, I have owned, acted as if they were missing or mis-firing because someone had put 85 gas rather than the 87 required for that specific engine. As I recall I put half tank of the highest octane 91 in the car to blend with the 85 and it solved the problem. This was after several mechanics had diagnosed it as plugs and wires, firing order and distributor problems.
NPR put a program on the air that stated if you were above a certain elevation then puttting 85 in a tank asking for 87, it would not matter. I found that to be inaccurate by my experience at 7000 feet above sea-level, here in Colorado.

What would be the octane ratting for hydrogen in a internal combustion engine?
Pump gasoline is a blend of several hydrocarbons, obtained in the refining of crude oil. A few of these are nonane, heptane, butane, octane, etc. Pure octane is the slowest burning of those used and the least likely to "explode" or detonate in the engine when ignited. Detonation causes mechanical damage and lowers fuel economy. The octane rating of any pump grade of gasoline is comapared to pure octane. 87 octane fuel is lower than 93 octane and will burn faster (not good). 100 octane is equivalent to pure octane in burn rate. Pure octane would be too expensive to use, so a blend of several hydrocarbons is used for various reasons. Hydrogen, I would think might burn way too fast in an unmodified gas engine, but have never read about any studies on this.
Using an octane rated lower than your vehicle?
Using an octane rated lower than your vehicle specification will damage the engine. I would recommend not doing that.
What is the octane rating of a 1995 Corvette?
You wouldn't want to use a low grade of gasoline in this engine, because that will lead to carbon buildup and engine knocking. It would be best to use at least a 92 octane in this car.
Can regular gas go in a Nissan Murano?
The owners manual says that higher octane is preferred for best engine performance, but it also says that 87 octane can be used without damage to the engine. I've been using a mixure of 87 and 89 octane and do not hear any engine-knock or pinging. The gas mileage probably would be better if 91 octane was used, but I haven't run a test on that aspect yet.
would using 98 octane fuel cause check engine light to come on?

What octane does a 1995 Toyota 4Runner need?
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!
What is the best gas to use in a dodge charger?
Depends on what type engine. the 2.7 L and 3.5 L are made for 87 octane fuel but can use 89 and 91. The 5.7 L can take 87 octane or 89 octane but i would use 89 for it. if i had the 6.1 hemi i would use the 91 octane cause it is a more consistent fuel.

Which is preferable 91 octane or 95 octane for Chevrolet Cruze 1.8 engine?
Neither. The Chevy Cruze is designed to run on 87 octane regular fuel. Using a higher octane will provide no benefit whatsoever. No more power and no better mileage. In fact it can cause hard starting. It would be a total waste of money to use anything but 87 octane.
