I just changed my oil from HD – 360 20w50 to screaming eagle syn3 full synthetic 20w50 now the problem when I start my bike which is a 2005 FLHRI the red oil light comes on and the oil is full. When I speed the engine up light goes out. Now when the engine is warmed up the light doesn’t come on what do you think I need to do? It never happened until I changed oil and went full synthetic.
If your oil level is correct, the light should only illuminate while starting, or when the ignition switch is on and m/c is not running. Changing to S/E syn 3 should have no bearing on anything. There may be an underlying problem.
Does this engine have high miles? What is this engines history? Has there ever been any work/upgrades done to this engine? Make sure it is not just something silly. Check, or change your oil pressure switch. Be sure that the wire/wires for the switch and indicator are ok, and not pinched anywhere.It never happened until I changed oil and went full synthetic. I was just talking to a friend he said it might be because it has just under 78,000 miles no work ever done. Do you think it might be the change from H – D 360 20w50 to the screaming eagle syn3 full synthetic? You should not have this problem using 20w-50 weight oil. Doesn’t matter if it is synthetic, non synthetic, made by: HD, Spectro, AMS oil, or Mobil. There is something else causing the oil light to illuminate. May be as simple as a dead short in the oil pressure switch, or indicator light wiring. Or an engine problem. If you switch back to the originally used oil and the light stays off, the found problem is not fixed. Look for any Harley error codes. Related Videos: Troubleshoot with Harley Error Codes
i have a 2016 hd tri glide trike. the oil came on as i was ending a ride and pulling into the garage. i checked the oil and it's full. after letting the bike cool i went out and when i turn ignition on the oil light comes on but goes off after starting and running but comes on after bike is off and ignition is still on. why???
I have a about the same problem, I have a 2005 harley road king twin cam, runs super for the last 5k miles ive put on it, So i switched to amsoil synth and after 1500 miles oil light comes on at idel only... What could it be???
I own a 2017 Road Glide Special with 17,000 on it. the oil light has come on now 4 times within the past 2 months. The oil level is fine. Fresh oil in it. I HATE this feeling of "oh no, can I trust this bike for the next trip."
Have 2016 FXDL, Sat for 5Mos, 1650 mi, Sat for 5 most indoors, Tank full, oil full,It has an oil light on and won't even turn over,Oil prime issues? Oil reset? Been into MC's since 10. ?????
Oil light stays on bike won't start. When I checked the oil there was none, I just had a oil change done, there is no way it should have been empty.
Heads up, if you are running an oil filter that is not made by Harley, that will cause a drop in pressure. Harley uses 5 micron filters. Great for increased pressure and keeps all the crap out of the oil, to a point. Spend money on a pressure gauge, then you will know if you have a pressure problem, or pressure switch problem, looks great also, custom!! Good luck, Larry
According to API: The American Petroleum Institute, The same viscosity test is used for both conventional oil and synthetic motor oil. In other words 20-50 Valvoline mineral spirits motor oil and screaming eagle 20-50 full synthetic must meet the same standard for viscosity to be 20-50w. Having said that don't out think this. Start with the simplest things first. Check the connectors and the wiring, Change the switch. Check the error codes. If it were me and I found nothing unusual and had replaced the switch I would check to see if it is wet sumping no matter which oil is used. The only thing I have ever had against full syn is it's tendency to leak. It is not a superior lubricant if it does not stay in the machine. If it stays in the machine it is definitely a superior lubricant. 78,000 and no motor work is not a bad thing. If there is a reason to do work you'll do it. Do not play with oil system problems they can get real expensive fast. Hope you get it on the road again soon.
How do I remove exhaust slip on that have been welded together from heat?
I have an 05 ultra , I bought an electronic oil temp/level that replaced the original dipstick. It worked fine with H-D oil , when I changed to Amsoil it quit working-I just wonder if it IS the oil?!
I had the same problem. It was the switch.
