as above, my options are:
Motul 8100 X-cess SAE 5w - 40 (100% synth)
Motul 8100 X-max SAE 10w - 40 (100% synth)
from my understanding 5w means that it has less viscosity at -18 C than the 10w. so with 5w its easier for the engine to start up relative to 10w?
cheers
yup! 5w operates better under colder temperatures, it flows more easily to coat critical components more quickly. Thus making it easier to start
Summer is coming up soon though so i would go with 10w - 40. :)
you don't start your car at -18
either will be fine
entirely depends on your engines internal condition. if it burns oil at an abnormal rate on something like a 5W then use a 10W, or a 15W. if it doesn't consume at an abnormal rate then stick with it. :)
my vti-r hated motul X-cess lol.
Pretty good oil currently using the xcess 5w40. Next change is approaching and It's made me consider weather going back to RP is worth it...but to keep on topic both are fine as said above.
I'm exactly the same, started with RP in my DC2r, tried out Motul and cant justify the extra $25 for what is probably very similar oil, and I definitely cant notice any differenceQuote:
