I'm seriously naive and can't really be bothered to understand the concept of which oil is good and which isn't. So, I'll just simply ask; is Castrol Edge 4L 5W-40 Engine Oil a recommended product to use?
I think it's Fahrenheit rather than Celcius but that's correct. Lower number before the W (which means Winter) means a more "fluid" oil; then the same applies after the W but I think that's at about 200F.It just means how thick they are below 0 degrees i IIRC.
so thickness depending on temperature.
doesnt really matter too much tbh as long as its fully synthetic.
cant go wrong with anything inbetween.
Im sure someone will be along to contradict shortly as i may be talking absolute balls.
