Depends on what you mean by too much. If you overfilled it by say 1 pint then more than likely no damage will be done. Simply drain out the excess. If, however you overfilled it by more than that then serious damage can occur. The crankshaft can make contact with the excess oil and whip it into a froth. This froth of oil mixed with air is a poor lubricant and will provide far less protection from wear than 100% oil. Drain out the excess immediately.
Adding even a small amount of petrol to a diesel engine tank can cause serious damage to the engine. Diesel engines rely on the lubricating properties of diesel fuel to keep components such as the fuel pump and injectors running smoothly. Petrol, however, has much lower lubricity and acts as a solvent. When introduced into a diesel system, it reduces the lubrication, causing metal parts to grind against each other, which can lead to premature wear or even catastrophic failure. Additionally, diesel fuel ignites through compression rather than a spark. Petrol is more volatile and can ignite too early, disrupting the combustion process. This can cause knocking, misfiring, and increased engine temperatures, potentially damaging pistons, valves, and the fuel injection system. If petrol is accidentally added to a diesel tank, the engine should not be started. The contaminated fuel must be drained completely, and the fuel system should be flushed to prevent long-term damage. At PETRO Industrial (petroinddotcom), we emphasize the importance of correct fuel storage and handling to prevent cross-contamination. Proper labeling, staff training, and using color-coded dispensing systems can significantly reduce the risk of such costly mistakes. Always double-check before refueling any vehicle or equipment.
the motor gets lubricated.
I assume you mean add fuel by pressing the accelerator. In which case the engine runs faster.
If you run it that way you will cause internal damage.
The engine dipstick is the only tool you can use to measure how much oil is in the engine.
Does not effect engine's output.
The amount needed will depend on how long the pan was off. Start with three quarts, start engine, shift through drive and reverse. You the check the level idling in neutral. Add fluid slowly until at proper level.
it will go cold
There is software you can buy to add a Blu Ray drive to your computer. However, many software systems are only compatible with specific computers, so you should figure out if the one you want will work with your computer.
It will not hurt the engine what so ever, But it will make it smoke and might fowl out a spark plug.
In normal everyday driving it will add no extra horsepower. In a racing situation at high rpms it will add some but not much. How much depends on the engine that it is installed on.
No distance! You can seize up the engine and require a total engine replacement. Don't even run the engine, but get a qualified individual to look at it. You may simply need to add oil to the engine.
