Let's see........
1. Bent valves
2. Caved pistons
3. Burned spark plugs......need I go on?
DON'T DO IT
You can run a higher octane in your engine if you like without worry about doing damage; except to your wallet. If you WANT to "bend valves" and "dish pistons" Camp Stove fuel will do a great job trashing your engine. It has almost a 0 octane rating.
Read "Octane Rating" http://en.wikipedia.org/wiki/Octane_rating here for more details.
In a nutshell, the octane rating describes a fuel's resistance to self- or pre-detonation when compressed, as in "pinging", "knocking" or "Dieseling". These undesirable effects will destroy a spark ignited internal combustion engine quickly and are hence VERY undesirable. For high performance (high compression) engines a higher octane rating is needed to prevent this pre-detonation.
SO, using a higher octane rating in an engine that does not develop relatively "high" cylinder pressures is largely a waste of money.
One point that the above web page makes clearly is that higher octane does NOT denote a slower burn rate for the fuel. Although slowing the burn rate does anecdotally produce a little more power, since power is developed longer throughout the power stroke. This is generally a desirable fuel characteristic that some have achieved by adding water vapor to the fuel/air mixture, which also raises compression slightly. But this is a very different topic… Fact is, most higher-octane fuels do burn slightly slower, or at least ignite slightly later in the stroke. Effectively this equals a small (almost imperceptible really) retarding of the ignition.
So, unless you're going to milling your heads, putting in a 'hot' cam and a "blower" and running at very high RPM much of the time, you neither need nor want a fuel designed for a high compression engine. It just a huge waste of money. You'd do much better re-tuning (reprogramming?) your fuel/air mixtures and timing curves.
BTW, I run a higher than recommended (87) octane fuel in my vehicle (93 usually) because it MEASURABLY lowers engine temperatures and improves my mileage slightly, especially since I tow often, requiring a rather high throttle opening (higher cylinder pressures).
Good luck.
no
you need a least 91 you can go with lower octane but you will not get the performance plus you will get knock and your timing will be re-tared and lose power and could damage the engine. Hopes this helps.
If it is intermittent it could be your not putting the right octane gasoline in the engine. Normally this will make it ping under load. If it has a clatter from the top of the engine all of the time you probably need to adjust your lifters. This is normally not a problem for today's lifters. Also if the noise is from the bottom of the engine you probably have worn bearings. Hope this helps.
The owner's manual suggests a rating of 91 octane and further comments that 87 can be used but could cause knocking in the engine.
Here is the best answer I can give you on this engine. I don't know what type of gasoline you put in this truck, but if it is 89 or below octane, it could cause this problem. I used 89 octane in my RAM for two years and lately I have had the check engine light come on. I had it checked by the Dodge service department and was told that it had two fuel sensors go out because I was using 89 octane gasoline and not putting any gasoline cleaner fuel with it when I filled it up. I would recommend you try this and see if it helps you out.
motor mount could be bad or broken
it could be your oil sending unit
Yep
i would imagine it could, but not without alot of work, the Buick engine is fwd while the camaro is rwd, you would need a whole different transmission at the least.
I own an 02 Highlander, and sometimes I get a knock when engine is under load, like going up a hill or when accelerating. This is engine knock caused by low octane gas. When I use a mid grade or premium octane, I do not get the sound at all. .
Well for one you could have a cracked head. Or you could have a bad seal on your thermostat though that is were it could be coming from.
It could have an automatic or 5-speed manual
