Thanks for the info, Kaudette. I've never seen 5W40 Mobile 1 here in the states. |

I had never seen it either before but I guess with the cold weather here in the winter it should be OK - I haven't found the V-twin mobil 1 15W50 yet - only Motul...
Anyone know why one should go for the 15W50 over straight 10W40 - is it for the very high temp or something? |

Yes, the Buell (and most air cooled twins) need 50W due to higher running temps.
Mobil One 15-50 is the tix for the Buell engine. I use 75-90 in trans.

What test are you referring to? (Forgive me I am new to this board.) I would like to see this comparison. Where can I find it?

HD recommends their synthetic 20W50 in the primary now. Has anyone used Mobil 15W50 in their primary? |

I've done a little more searching through the archives and found that some people are using 15W50 in their primaries.
Any of you people care to comment? Are you still using it? Switch back to a gear oil? Yes? No?
If HD says to use their 20W50 and there is just a C-hair difference between 20W50 and 15W50, I'm thinking there isn't any reason why I shouldn't use Mobil 15W50 in my primary. Thoughts? |

hoot.. i use the mobil syn gear oil 75w85? something like that. about the same viscosity as 20w50 but without the additives for engine oil. i do see where a lot of folks are using the motor oil with good results. |

I'm now using Mobil 1 20W-50 V-Twin in both the crankcase and primary/trans. No difference in shifting (compared to Mobil 1 gear oil and Mobil 1 MX4T oil) and it's just simpler to pick up the one item at the auto parts store.
If you are still using dino oil and semi-syn SporTrans, you should switch to synthetic now. The brand doesn't matter as long as it's a major brand and you change it regularly along with the filter.

I've been using either redline or mobil in the engine, and sportrans in the primary. I used redline heavy for a while, but a few years ago I quit and switched back to sportrans. |

22,000 miles on Mobil One 15-50 in both crank and engine, no problems. Change every 2500 miles. Tried the Mobil One gear oil, but could sense no difference, harder to find, twice the price. I watch for Mobil One on sale at $4/qt and Ford FL1A filters (or equivilant) at 2/$5. |

i think any synthetic 20/50 is good enough but i only use the best. for the last 39,000 miles i've run red line 20/50 and 75/90 in the tranny of my sportster. the tranny runs much quieter. the reason red line is better than mobil 1 or harley synthetic is because those brands are a blend of synthetic stocks but red line is made of only estor stock. the reason companys like to use a blend is because it's cheeper. even so harley oil costs more than red line. red line has come out with a new 20/60 just for harleys but i have'nt tried it. |

Just because Redline is not blended stock (I don't know if that is true or not???) doesn't make it "better". The best oil is one that protects, cleans, cools, lubricates, and maintains it's viscosity the best.

Mobil One claims that it is fully synthetic and even sued Castrol when they apparently were using that claim but were using blended synthetics.
In any case, I have used Mobil One 75-90 in my trans since 300 miles and it shifts better now than any bike I have every owned.
15-50 in the engine.
I will likely use that 20-60 next summer for added heat protection. |

mobil 1 used to say tri blend formula on the front of the bottle. they changed it to now to say supersyn anti-wear technology and on the back of the bottle in small print it says "with a unique combination of high-performance fluids", this is code for blend.( i run this cheap stuff in my truck) hd syntheytic is named syn3.
there're two kinds of blends. one kind of blend is synthetic blended with dino oil. this is not what i'm referring to. oils like mobil 1 can say they are pure synthetic and still be a blend because there are three kinds of synthetic base stocks that they can use. the best of the three is estor stock. it's also the most expensive. going with a blend is cheaper and still better than any dino juice. red line and also amsoil are made of only estor stock. mobil 1 and pensoil syn are blends. i don't know about castrol syn but it's probably a blend too. when my 88 sportster was new i only used hd 20/50 and sportrans fluid. i always changed it every 2000 mi. but i changed it at least three times before the first 2000mi. at 28,000 mi the roller bearing on the intake lifter of the front cyl failed. i told my wife it failed because hd oil sucks and the motor needed to have more hp. that was only half true but it made it a lot easier to get 50% more hp after the repair. i found plenty of wear in my motor. at this time i switched to red line. about 20'000 miles later i was getting paranoid about the lifters so i tore it down and replaced them. i found almost no wear then, even on the high wear oil pump pinion gear. at 69,000 mi it started leaking oil between the block halfs, sucking the tranny oil into the crankcase. this is the only time this bike has been in the shop. it was torn down by their best machanic with instructions to replace anything that looked worn. total of all parts replaced, the rings and the cylinder studs. even the oil pump pinion gear still looked good. this has made me a believer in red line, but probably when you change your oil as often as we all do it makes little diff. sorry to blow so much wind but i love my bike and try to take the best care of it that i can. |

Good stuff. Thanks.
PS-did you ever read the 1 Million mile story on the BMW with Mobil One. Interesting stuff. |

biknut - ANY major, non-snake-oil brand of full synthetic oil is better than HD 20W-50 (dino) and HD SporTrans (semi-synthetic), whether it's a blend or not. I can't argue that HD oils are inferior, but let's see the proof that oil alone caused the failure of the "roller bearing on the intake lifter of the front cylinder" on your bike, after all it is a Harley! A testimonial by your wife would not constitute proof.
You sound like a charter member of the AMSOIL or Redline Cult because you believe all of their hype!
You don't even like Buells, so what's up with that?

Redline is not hype. They make damn good oil. It's just 2X the price. The only reason I don't use it anymore is because I have to mail order it or drive 60 miles to get it. |

I'm thinking of switching from HD recommended fluids in both trans/engine! There has been some discussions regarding clutch slip when u go over to full synthetic.
Is there a reson for worry or should I just get on with it??
Thoughts on this would be appreciated!

Clutch slip is a myth. Just get it over with and run synthetic oil. Your bike will thank you. Also, HD does recommend the use of synthetic oil in both engine and primary. |

i have'nt noticed any clutch slip from red line 75/90. i did have some problems with clutch slip from over filling the primary. my bad, i was just filling it up till oil came out of the leveling hole on my 4 speed, but after changing the wheels and suspension on my bike i forgot the angle of the dangle was changed. after i poured in the correct measured amount i discovered it took about 4 more ounces to come out of the leveling hole. the clutch did'nt really slip but just before it got to the red line it would just let go. i replaced the whole clutch before i figured it out. oh well just more spare parts for me. |

Been using Mobil One 75-90 in my trans since mile 300 and no slip. Great improvement in smoothness too. |

Well back in the day, I ran Mobil 1 for V-twins in the motor and Redline Heavy shokpruf in the tranny. The Redline made a real diffrence in the tranny. I too had to mail order it, kinda pricey but I felt it made a difference. That was in a S1W that had been Nallinized. |

I am running Mobil in my motor, Harley in the tranny. I am switching to Amsoil 20w50 soon. If you check the net you will soon notice that Amsoil challenges any other oil to outperform it for reducing wear and tear to moving parts. However, that being said, any synthetic will outperform standard motor oils, since they have very little breakdown contamination. The only worry in using some brands in the tranny are "friction modifiers" which in making the oil slicker, can also effect the grabbing effect needed with clutch components. Neither the Harley or the Amsoil have friction modifiers, so they can be used in the tranny. I have not looked into the Mobil 1. |

amsoil 20w50 v-twin oil was designed for HD engines and primaries, I'm just waiting to get 8000km of break in done with dino oil then switching! |

How much is Amsoil 20W-50 per quart and where can you get it? |
