I have a Honda gx390 powered 4gpm pressure washer. At maximum power it runs 4,000rpm, has about 30 degrees of ignition timing advance and runs wide open throttle.
Seemed like it ran pretty hot. So I found a oil temperature gauge that goes in the dipstick hole to see how hot.
I ran it on a nice 80F day. The oil topped out at 260F. I figure on a 100F day that could make for 280F oil.
That seems a bit hot.
