Asked in American Cars, Decade - 1990s
Do you need to use high octane gas in vortec engines built in the 1990s?
On what Vortec engine you are talking about. The vast majority do not require the use of Premium fuel. Use exactly what your owner's manual lists. Using Premium in an engine designed to run on Regular is a waste of money and provides no benefit whatsoever. No more power, no better mileage, nothing! Anyone who tells you different is buying into the myth, and that is all it is, a Myth. But if the engine requires Premium then use Premium. Using...

Why is there pinging from the engine of 2000 Honda CR-V?
(1) Using fuel of insufficient octane. (2) The engine timing is off (3) the combustion chambers/pistons needs to be decarboned. ...
Asked in Chevy Blazer
What would cause pinging in a 2002 Trail Blazer?
Pinging, knocking and detonation are all terms for a condition known as "pre-ignition,". That means some of the gas and air mixture is igniting in the cylinder before it's supposed to. And when that extra flame front crashes into the normal flame front (created by the spark plug), you hear a noise, and that noise is pinging. Pinging is something you want to avoid if possible. Engine damage can occur if pinging is severe. Pinging is caused by using too low an...
Asked in ATVs, Four-wheelers
What causes pinging in a 2011 polaris 550 ATV?
Try using a higher octane gasoline in this ATV. Many times the pinging is due to not using a 91 or higher octane fuel. A lower fuel like 85 or 87 may not be burning off as efficiently as the 91 octane which in turn will cause the pinging. ...
Asked in Nissan Murano
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. ...
Do you have to use 91 octane gas in a 1996 Cadillac Deville?
Use exactly what your owner's manual states. If it says 89 or 91 octane then do not use 87 octane. Using a lower octane that required may cause pre-detonation or what is commonly called (Pinging). Pinging may be harmful and may cause engine damage. Bottom line is to use no lower or higher octane fuel that the engine was designed to run on. Using a lower octane can cause engine damage, and using a higher octane is a waste of money...
Asked in Nissan 240SX
What fuel is recommended for 1989 240 sx?
I used regular in my '90. Rule of thumb: If your car doesn't ping using regular grade, it's fine for your car. You would be wasting your money on anything more expensive. All higher octane gas does is keeps your car from pinging. ...
Asked in Chevy Silverado
What would cause engine pinging in a 2006 silverado with only 27k miles?
It is probably spark knock from using a low octane gas. Try using a higher octane gas for awhile and see if it goes away. If it does then that is the problem. It will not hurt anything but it can be annoying. Lower octane gas burns faster and sometimes causes a pinging sound while accelerating. Some people say there valves are rattling but that is not the case. ...
Are there any issues with using regular gas vs premium gas in the Buick 3800 Supercharged engine?
Right. If it calls for Higher Octane, use it. :) Unfortunately yes. ...that is...if you FLOOR it... High boost, and load need a higher octane, so as not to "ping" which can cause damage over time.. good luck dave I have a 1996 Buick/Riviera _Supercharged Owners manual recommends using premium fuel, if supercharged. I put "regular gas" in by mistake & It wouldn't go over 55 MPH. Gil Raker I haven't noticed any difference, at least as of yet. With the high price...
Does higher octane produce higher co?
Higher octane is helpful for high compression engines. High compression causes the combustion to take place faster and can cause pinging and a loss of power. By using high octane with high compression you get the advantage of the extra efficiency of the high compression engine and the delivery of the combustion across the power stroke of the piston, with out pinging. ...
How to stop pinging in your olds with 305 engine?
Either find a way to lower the compression, or use higher octane gas. Pinging is caused by premature ignition of the fuel, usually due to compression. Higher octane fuel is less combustible than lower octane fuel, so it's usually a good solution. With gasoline prices what they are today, using premium in an engine that was designed to run on regular is an expensive solution. You may end having to do that very thing but try some other things first. First have...
Asked in Honda Civic, Honda Civic EX, Honda Civic LX
What is the recommended gasoline grade for a 1991 Honda Civic LX?
87 Octane. Using a higher grade is a waste of money. The engine will perform no better and get no better mileage. The only time a higher grade is necessary is if the engine is experiencing pre-detonation, commonly called pinging, and you cannot otherwise cure the problem. As per the original manual you should use 91 Octane. Using lower octane will result in pinging and some time loss of power specially when climbing uphill. If you have high milage on the car...
What could cause a pinging noise in your 2001 Nissan Pathfinder during slow acceleration?
This vehicle requires the use of Premium Fuel, and the use of Regular will cause pinging and eventually do damage to the engine. If you are using Premium, then either it is out of time or has carbon buildup. Have the timing checked and pour a can of Seafoam Motor Tune in one tank of gas to help remove carbon buildup. Can be purchased at most Auto Parts stores. It may take more than one application. Follow directions on the can....
Is it alright to use unleaded plus instead of regular gasoline?
Read your cars owners manual. Most vehicles only require regular gas. Those cars normally do not need a higher grade unless you hear a lot of pinging in the engine. Using a higher grade fuel will not hurt the vehicle in most cases, it will just cost you more out of pocket. Some auto makers do include a warning about ethanol and the maximum % you can use so read your manual. ...
Asked in Subaru Forester
What is detonation?
Detonation, knocking, or pinging in a gasoline engine is caused by an improper burn in the engine cylinders. As the spark plug fires and the fuel begins to burn detonation has the fuel also starting to burn in another location within the cylinder. When the two flame fronts come together it causes the characteristic "pinging" noise like marbles in a coffee can. It happens very quickly. This process can cause engine damage to the engine by the pressure created where the flame fronts...
Asked in Ford Laser
Your 1989 model Ford Laser engine is pinging how do you fix this problem?
All Ford Lasers of this year require Regular fuel except the GT-X which requires you use Premium fuel. If you are using the correct fuel then your engine may be out of time, which will cause it to ping. Have the timing checked by a professional. If it is not out of time and you are using the correct fuel then it more than likely has carbon buildup. Purchase a can of Seafoam Engine Treatment and follow the directions on the...

Asked in Fuel and Engines
What is engine flush?
You add a product to your oil and let it circulate throughout the engine to clean or flush out all the built up grime and gook that occurs as a byproduct of oil. These byproducts can cause lubricating issues in the engine, and lubrication is key in any engine. The idea is to get regular and routine oil changes with quality oil and a filter to avoid these issues. Engine flushes have their place, but be sure you have a need for...
