Nothing, unless you live in Alaska or have a really picky car. Both would work equally well. The numbers indicate the weight of the oil or range of weights. 5w-30 would be a little better in cold weather. The "5" indicates a lighter oil, less thick. Oil thickens when its cold and thins when warm. Again, both would work and usually cause no problems. Just be sure to use a quality oil.
Almost a common misconseption that 'W' does not stand for weight. It actually stands for 'Winter'. So basically as stated above...
5W - Can be used for Negative 20 Degress
10W - Not for Negative 20 Degrees
Hold it - that's a bit misleading - thinner multigrade oils are now common in modern engines. The Ford engines now require 5W oil to operate the hydraulic valve adjusters, using 10W has been found to cause hydraulic locking of the adjuster resulting in loss of performance and valve damage. Synthetic oils are also now specifed as the oil does not break down so quickly. This allows longer service intervals typically 12 months instead of 6 months when using mineral oils.
Always use the oil specifed - apart from advertising a particular make, there is always a reason for the grade
10W30 would be used in cold climate. 10W40 would be used in hot climate. 30 and 40 means the thickness viscosity when warmed up.
I would use 10w30 and for high mileage 10w40 would work best
What happens when your heart stops? The motor would seize, thus no more motor!
why would you want to? Yes you could, the viscosity will average out .
If this is an AC motor nothing will happen but if this is DC motor then the rotional direction is reversed with reverse polarity
SAE 5W30 or 10W30 I would recommend the SAE 5w30 synthetic blend.
5W30 would be fine, I believe that is the recommended viscosity for the Mitsubishi motor in that vehicle, also 5W20 or 10W30 would be fine during the summer.
I would stay with 10W30 oil. If you are using alot of oil due to engine wear, try 20W30.
you can put castrol 10w30 but i would a brand made for motor cycles like motul or the factory oil
I know the 4.0l 6 cylinder suggests 10w30 motor oil, but I'm not completely sure for the 2.5l 4 cylinder. 10w30 would make sense for that engine, but check your owners manual for more clarification.
Ford recommends using 5w-20 so why would you want to use 10w30? Do you know something about this engine that Ford missed? Use 10w-30 at your own risk.
they will die
Long as your only unsig it in your lawn mower then no problems. Just don't leave it sitting around for weeks as normal motor oil will separate from the fuel faster than 2 stroke oil.
The motor function supplied by those nerve would be impared.
The owners manual recommends 5w30 or 10w30I would not use 20w50.The owners manual recommends 5w30 or 10w30I would not use 20w50.
If the motor is synchronous, then its speed will not change as the load changes.
The motor would operate above its rated RPM. The motor would start to get hot as the current draw would be greater. This might eventually burn the insulation off of the windings and cause the motor to short circuit.
loos of motor function
If the recommended oil is SAE30 why would you use SAE 10W30? Some mowers recommend either of these weights but if your recommends 30W then using 10W30 will cause it to use oil.
if the power wires for the motor happen to be hooked up backwords
That would happen when a three-phase motor is used. It can be connected in star or delta dependig on the manufacturers' instructions.
No, it requires 5W20. Using 10w30 would cause improper operation of the variable valve timing system.
I would use 10W30 unless it burns a lot of oil, in which case I'd use 10W40. Any brand should be fine.
You can, but I would not recommended. Due to it's not a new truck and high mileage. You can put 10W30 or 10W40 instead. I think the 5W30 may hurt your engine.
You can but I would not advise it. Use only 10w30 or straight 30 weight. I also highly recommend using Synthetic in an air cooled engine.
