How many hours/miles before you change oil?

[Chris142]

I have a 1990 kawasaki KLR250. It's watercooled and uses the same oil for the engine and trans. I put some temperature stickers on the case and the radiators to keep an eye on temps.

I have never seen the engine oil past 160F.

The rad does have a cooling fan that comes on @ 185F. I have seen it get to 212F which is touching the red on the stock temperature guage.

Anyway I really don't consider 212F hot an I have been running Rotella 15w40 in it. Been changing it every 300 miles or so.

Should I keep doing it @ 300 miles or go longer?

if the bike is street ridden 300 mile on the oil is nothing, tripple it

I'm wondering how long to run 4oz ARX in my engine, AC Suzuki 750, the sight glass is clean, bike is very clean,23k. Rotella. I figure just run as long as possible, all summer???

300 miles seems awful short. Unless that is all off road miles I think you are wasting good oil. If you aren't running all that hard I would change it every 1000 miles.

I realize that it's apples to oranges, but I usually change the oil in my GSX-R600 every 1000 - 1500 miles.

Oh I forgot to mention 99% dirt/Dust.

I let the airfilter go 1000miles W/O checking it and could not believe the dirt on it. I don't know how it was breathing through it.

what is the sump capacity?

I always believe that clean fresh oil is always better. Especially if in very dusty/dirty conditions.

1000 miles and cleaning the air filter regularly would be wise.

Just under 2 qts.

on my crf i change about every 2-3 rides. motor side is 690ml, transmission side is 600ml. so around 1.5 quarts.

I change out pretty regularly as under a quart on each side is not very much, so I prefer to have fresh oil in there pretty frequently.

The same type filter on the street will go 10,000 mile easily

but if your talking offroad 4stroke about every other ride on the oil
