do you mean "higher grade" as in better quality? If so No. If your talking about the rating numbers(example:10w30) you go by the lowest temp weather your riding will be in and highest temp weather. I don't know how that whole thing exactly works but the numbers deal with viscosity of the oil. Just use what the manufacturer of your bike tells you.
Try to use a higher grade gasoline or dry gas.Could have moisture in system.
Regular gas is the recommend grade of gasoline for the 2000 Corolla. You can use a higher grade, if regular is not availalbe. No damage or performance changes will be present. In some cases, due to the natural accumulation of deposits in the engine, some high mileage examples will exhibit less engine "pinging" under heavier loads or even experience a slight increase in fuel economy.
I don't believe there is a such thing as a leaded fuel engine. All gasoline is unleaded, some just a higher grade.
Yes, using low octane gasoline in an engine designed for higher octane fuel can lead to serious engine damage over time. This is primarily due to knocking or pinging, where fuel ignites prematurely in the combustion chamber, causing increased pressure and potential damage to components like pistons and valves. Persistent knocking can lead to reduced performance, efficiency, and ultimately, catastrophic engine failure if not addressed. It's essential to use the fuel grade recommended by the manufacturer to avoid these risks.
Burning low-grade fuels can release higher levels of pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter, which can contribute to poor air quality and health problems. Additionally, low-grade fuels may produce lower energy output compared to higher-grade fuels, leading to decreased efficiency in combustion processes.
If you mean it ( diesel's ) then eventually shuts off, then this is due to low grade fuel as to where the timing is set on the engine. Two options, change to higher grade fuel, or have timing checked or lowered. In either case, this is not good for the engine.
If the pressure is too high for the grade of fuel, you will get 'pinking' or 'pinging'. This is the term for pre-ignition. The fuel will explode instead of burning rapidly, and makes a metallic rattling or 'pinking' sound. This can damage the valves and piston crown if left to continue. High compression engines need a better grade of fuel, a higher Octane number.
Most likely is knocking. Try next higher octane grade of gasoline.
Yes, higher grade stainless is achieved by cold working a lower grade stainless steel
It signifies the grade of a bolt. For a load bearing bolt where it's failure could cause injury or damage, you should use a high grade bolt. 5-9 are higher grades.
The 2.2 liter VTEC (H22A) engine recommends top grade (premium) fuel due to higher compression. You may use lower grade (lower octane) fuel but run the risk of damaging the engine and will surely reduce engine performance and reduce fuel economy.
