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 else can I help you with?
What is the Best octane for a 1985 Chevy trk 4x4 5.0?
92 or 93 octane would be the best for that engine.
What would happen if you fill your gas tank with 87 octane and the manual calls for 90 octane what would this do to the engine?
just use sunocco ultra 93 it should be fine.

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.

Is there any formula for calculation of octane no?
Calculating octane is a compex process, but the formula is simple (the difficulty is getting the values from the manufacturer). Gasoline pumps typically post octane numbers as an average of two different values. Often you may see the octane rating quoted as (R+M)/2. One value is the research octane number (RON), which is determined with a test engine running at a low speed of 600 rpm. The other value is the motor octane number (MON), which is determined with a test engine running at a higher speed of 900 rpm. If, for example, a gasoline has an RON of 98 and a MON of 90, then the posted octane number would be the average of the two values or 94. See related links for information about computing octane numbers.
