Checking oil on a Rebel

This should be a sticky thread because it keeps coming up.
To check oil on a Rebel, Remove the dipstick and wipe it dry.
Stand the bike up straight or sit on it with the bike straight up and down.
Insert the dipstick in the hole without screwing it in.
Withdraw the stick and read the oil level.
The wet sheen of the oil should be somewhere up on the crosshatches on the stick.
Do not fill above the cross hatches. This risks blowing out the oil seal on the crankshaft, and/or coating the paper air filter with oil.
Do not allow the oil to be so low that it is below the crosshatches or off the stick. This can ruin your engine quickly.

Thanks for the information. That's always been on my mind since I always change the oil while the bike is on the kick stand.

I always check my oil warm. Oil, like everything, expands from cold to hot.

I highly recommend having the oil level at the very top of the crosshatch area. The Rebel doesn't hold much oil, and if the level is already low, and it burns a little or leaks a little, it's bye bye engine. I don't believe the oil level affects the pressure. The crankcase is vented. It is a 360 degree twin, and unlike a 180 degree twin, crankcase volume is constantly changing while the engine runs. That's why having a properly operating crankcase vent is so important. But, when the engine is running, especially at highway speeds, most of the oil is being circulated through the engine, with very little in the sump.

Does anyone know roughly how much oil it takes to get from the bottom of the crosshatch to the top? In case it matters mine is an '86 Rebel 250.

In fact, the Honda Rebel owners manual says to check the oil level AFTER warming up the engine.

On my 2016, using 10W-30 oil, the difference between the cold and warm readings seems to be 1 1/2-2 hash marks on the dipstick.

Not sure, but would guess about half a pint or so. If you are changing the oil, it's just easier to pre-measure 1.6 quarts and add that. That should bring the level up to at or near the top of the cross hatches.

Keepin' all the left over parts. Gonna use 'em to build another bike!

Thanks for the reply! I'm not quite due an oil change yet (been about 2,300 miles) and noticed it was on "add" today when I checked. It took roughly 12oz. to bring it back to nearly full.
