Because oil is vital for lubrication and cooling of the pistons, and without it, the engine would seize and be ruined.
Combustion engines allow a car to transfer potential energy stored in gasoline into mechanical energy that powers the pistons to turn a cars' wheels. Simply put, engines, such as the high performance st205 used by Toyota, allow cars to move.
Its Sodium Silicate, when this chemical is heated it turns into a glass like substanceThey drain the oil and put the solution in the oil pan and run the car till it hardens and the engine will not run.
Yes, but they make it into gasoline first. Crude oil is not the oil you put in the crankcase. That is oil that is refined from crude oil and then additives are added.
No, seals are cheap, engines expensive.......
The aircraft mechanics usually put propellors on.
Most small engines will run on 30w oil .
most engines take 5w30 unless the oil cap says otherwise
Check the drivers manual, it will show you where the engine oil goes in, how much to put in and what type to put in. Normally the filler cap is on top of the engine itself, on top of the rocker or cam covers. Modern cars have a picure of an oil can moulded into it, older cars may have the name 'oil', or equivalent language such as 'Olio', for Italian cars.
Not recommended. The engines call for 5w30 or 5w20.Not recommended. The engines call for 5w30 or 5w20.
You will be fine with 10w-40 ATV or motorcycle oil designed for wet clutch engines.
You can put whatever oil you want to put in an engine as long as it is the right weight (10W-30, 5W-30 etc...) and it says "made for gasoline engines".
No not the oil filters, just the fuel filters You don't have to. But I put oil in them when I can. Just the way I was told to do it when I first started working on engines.
