how many quarts of oil for 400EX?

[cyba888]

How much oil do you usually use for a 400EX? I just bought some Castrol Oil which is 4 stroke oil, 20/50 Its kinda of chilly(around 65 degrees)where I live so I guess it should be ok?

65* isn't chilly, I guess in L.A./Taiwan it is lol!

When changing the oil and filter you sould need to add just under two quarts. 10/40 should be good for your temps.

The higher the weight means it is thicker and its used for colder temperature riding?

No...... the numbers 10 - 40 or whatever combination the first number is the viscosity (thichness) in cold or at start up.... the higher number is what the viscosity goes to when it heats up....
So lower the first number better for cold weather it flows better. Higher the second number better it holds together when heated.

I would suggest you go to some sort of syn. oil ..... it takes the heat that you will be generating when you ride hard and the area you are in does not have really cold weather ...

I would suggest Mobil -1 since you can get it most anywhere.... or my choice is Royal Purple... runs about $6/ quart but you do not have to change it everytime ya ride unless you get it to some deep water......

I would also suggest a temp gauge for you oil tank gives you and idea when to back off and let the oil cool a bit .... most concern would be in the sand ... when it will be working the hardest....

Oh with oil filer change just under 2 qts.,.... if you rebuild it will be allmost 2.5 check it then as you do the break in.....:p
