I'm one day into an oil change on my Road King useing M1 5w-50 and am a we bit nervous about this venture. Appreciate any solid feedback you may have out there!
There's several reasons why I'm running this, the main being I'm in SE Asia and availability. I've met a few others here useing it with high regards but would still like some thoughts from you guys.
So far I can't notice any difference from the dino oil I was useing except for start up oil pressure (a little lower wich is fine by me). Hot idle & cruising rpm's seem to make the same pressure as the dino oils.
I will continue to moniter & would love to hear what you all have to share on this. Thanks in advance!
 
Yes, 5w-50 for gas engines. I think it's an oil Exxon/Mobile distributes on this side of the globe. I didn't see it on the US web-site. The only other M1 available here is 15w-40 for diesel's.
Thanks!
 
Run it, I dont think it will hurt anything, top end may br noisey though. Lots of prople run 15w40 in thier harleys. Motorcycle oil is a waste of money for your engine. I use 15w40 rotella in the primary.

The only 5W50 i can find is Castrol Edge & Redline.
 
That's the stuff DuckRyder. I agree RoadKingnc, always ran M1 15w-50 in the Eng & Primary back in the States. Noise isn't an issue yet but a typical ride here will have you coming off the highway into stop & go traffic for great lengths of time, and it's hot here. We'll see, but in the mean time I'm confident that startups are much easier on the engine. Here's the data;

Thanks!

Your engine surely will not blow up on the 5W/50 but beings Harley recommends 20W/50 in most cases - that is what I use. I've used 15W/50 years past fine - but 5W/50 just doesn't sit well with me.

True. http://www.harley-davidson.com/pna/pa_chart_oil.jsp?PRODUCT%3C%3Eprd_id=8455244420907


But doubt he is riding at 40 and under. 20W/50 is still the better choice.

Go ahead and use it. It's a 50 grade at operating temp. I've used that exact oil in my Harley once. Because of the grade spread it MAY shear a bit quicker than a 20w-50 however there is no way to tell without a uoa.
Forget the naysayers. Your bike will not blow up.

Just to clarify, I'm from MN but have been living in Thailand; hence the availability factor. 9 months out of the year here are just plain hot as [censored]. Now coming into a cool down period (winter?) where mornings may see 50's-60's soon, but days still get in the 90's with a heavy humidity all year.
I've installed a Tmax ECU so my maps are not lean. Also installed a substantially bigger oil pump & have a small oil cooler coming off the filter & a medium size oil cooler off the engine to pan line. Both coolers are on the crash bars so no engine air is choked. Also have a parade fan. So my engine temps aren't going to get crazy hot but never the less, it gets miserable on the asphalt at times, especially in traffic.
At this point with the M1 5-50 I've noticed a little (ocassional) ticking in my front rocker box that wasn't there with the dino oils & other then a lower start up pressure, oil pressure's are the same.
Also to clarify, I was using Pulzar (used to be Penzoil here) SAE 20-50 CF-4/SG and Mobile Delvac 1350 SAE 50 CF/SF. A 50/50 cocktail.
I always liked M1 15-50 back in the States and would love to take a run with Redline 10-60 here http://www.redlineoil.com/product.aspx?pid=130&pcid=21
unfortunately the guys with the shiny black shoes love it when forieghners bring in things like oil, tires, ect.. Not worth the hassle & expense so I'll use what I can find on the shelves here.
So with the clarifications I;d appreciate some more facts & opinions. Great forum by the way!!! Thanks!
 
A couple of fellows I know have been using Castrol Edge 5-50 for a long time with no issues. It used to be a 20-50 oil and then was re formulated and is still recommended for older flat tappet engines. According to manufacturer they have added more zinc to it.

I don't know if Mob 1 5-50 is the same but thought I'd suggest what another brand was doing.
 
edge on my bike? [censored] no.

if you hi rev / hi temp the bike, stay the [censored] away from edge, it sucks for hi rev/temps.

last thing you want to see is an iron rose on your magnatic oil drain screw.

I learned it the hard way.
 
Update on running M1 5w-50.
This oil looks great, hi VI & many API's including a diesel & SN rating (lot of ethanol here). Problem is it seemed to be getting through the breathers & down the throttle body. Even with the oil level on the lower side. I'm sure the larger volume/pressure oil pump helped it along also. I ended up removing 2/3rds of it, replacing with Mobil Delvac SAE 50. Seems to be ok now???
Any opinions out there on the Delvac 1350? It has the same API's (cf/sf) as Delo SAE 40 which I read many good things about on this forum. No Delo 50 here though. The Delvac 1350 is the only SAE 50 I can find here. By the way, Harley does say diesel oil is a safe alternative.
There is Harley oil available in Bangkok. Personally I've never had any interest in using it in the past and am not going to start now at $13.50 a quart. They stick it to you even more over here
