Using oil

Postby jtimgrant » Mon Nov 04, 2013 11:15 am



My '87 has 85000 miles and is using oil. It did set up for around 5 years. The amount of usage varies from barely negligible cruising around at 55 mph to as much as 16 ozs in 300 miles at interstate speeds. Absolutely no leaks. Cylinder compression is 155 on all cylinders.The plugs are clean and there is no smoke - ever. On start up or cruising. I had the exhaust off to replace the crush washers and the headers are dry. But the signs of oil usage is evident. Dirty residue on rear of bike. Sooty exhaust. And of course the level drops on the stick.

Now, here is a theory or the musings of a madman burned on an Craigslist purchase . . . since the plugs show no fouling could the oil leak be at the exhaust valve stem seals allowing oil to leak into the exhaust stream and be burned by the exhaust? That would explain the soot and the clean plugs. I'm also wondering too if the valve covers should be pulled to check for an obstructed oil return since this bike set up for several years.

Thanks

If it were mine. I would try running 8oz of MMO or seafoam in the crank case with your regular oil for a couple hundred miles and then change the oil and see if that loosened up anything... May have a ring stuck on a piston or two. Then again could be a leaking valve seal..... Let us know what you find.
Enjoy the ride. They are all good, just some better than others.

Mooseman,

Thanks for replying. I ran some seafoam in the crankcase for approx 500 miles back a couple months ago and what I got was very black oil so it seemed to need cleaning. With this oil change I decided to try something different. I changed to 5-40 Rotella syn to see if the bike just doesn't like the 15-40 rotella. I have 300 miles on the oil change with no usage yet BUT I have not been on interstate. What I did find quite by accident is my front right and rear brake calipers were sticking of course causing the brakes to drag ever so slightly. I rebuilt both the front and rear calipers along with the rear master cylinder. Cured the problem. Checked my mpg's today after a 200 mile ride. 48.2 mpg where it had been running 40 to 43. Maybe the drag was causing some lugging? Again, just a guess.

I will report what I learn as to oil usage after a trip down the interstate.

"I changed to 5-40 Rotella syn to see if the bike just doesn't like the 15-40 rotella."

I have used the diesel oil's since I picked up my wing a few years back. The bike had 20 k when I picked it up. My first couple of oil changes, the oil was dark with crud. Now it stays golden till just before changing every 5k.
Let me know how you like the 5-40? I have always used the 15-40.
Enjoy the ride. They are all good, just some better than others.

Not seeing any change in the oil usage. Both rotellas are consumed the same. A recent interstate trip at speeds of 70 to 75 for 150 miles consumed 12 ounces. The return trip of 150 miles through the country - 55 to 60 - very little if any usage. Plan to replace valve seals. Riding buddies following say they see no smoke. Exhaust pipes are sooty with a sticky soot.

I would never use an oil that is made for a Diesel engine in a motorcycle.Diesel engines are very low revolution,the oil will breakdown at high revs.It is not even recommend for autos.I would bet if you would use better oil like Castrol or other oil recommended for your Honda,it will quit burning oil. Thanks

Hi Dale,

Thanks for replying. I have used rotella in all my bikes for the last 10 years without any problem. This goldwing is the only bike to ever use oil. But i do intend to switch to castrol at next oil change in hopes oil usage will drop. Also i am replacing valve seals.

Again, thanks.
