FE/FC Favorite oil?

Hey guys, first post here! So I recently picked up a 15 fe501. I'm coming from the ktm side of things and was wondering what oils you guys like and have had good results with. I've always been loyal to running rotella 15w40 and constantly looks new on every tear down. I have been reading good things about the Mobile 1 0w40 euro formula. I run that in my car but don't really trust anything that thin in my bike, yet.

first post? welcome!
Starting with an oil question? Are you nuts?!

There is a long oil thread in the 4t section dedicated to M1. What I can say is I've been using it in my 2015 501 basically since new. No problems with it. But I haven't torn down the motor yet either, so I'd have to say it falls somewhere between "the best oil ever" and "catastrophically horrible"...I think its about as good as any other more $$$$$ motorcycle specific stuff, but its oil, so there will be 1,000,001 opinions!

After you digest the Mobil 1 info, if you need to kill some more time with another controversial topic, dig into the 4CS threads here and elsewhere. That'll give you reading material until about June!

Have fun on the 501, they are great bikes!

I like Shell Rotella T6 5W40 in all my bikes.

Paw PAw

I like peanut oil.

Olive is good for general cooking.

I'm with Reveille on this one! Olive oil has a lower flash point, peanut oil is better, specially for fish frying!

Castor oil is my all time favourite but it doesn't taste as good as it smells....

Put in Mobil 1 0w-40 n stop all this madness lol. It's a great oil/blend n you won't look back

Come on, don't ruin the fun of the oil thread!

Nice huskynoobee well stirred...I sure miss Tinken and Kelly along with some others. Had valves adjusted recently and everything looked well, that's it I'm switching to 50w gear oil...

So just out of curiosity I did a search on the Mobil 1 and came across this. Couldn't find anything on fc race bikes being damaged by Mobil 1, thanks huskynoobee for peeking my OCD, this just seems too thick but what do I know. I remember tinkin saying something about thinner oil equals more flow and better coverage and oiling for tight tolerances. Kelly said he's been running it for years with no issues. Ok ok I'm done lol sticking with Mobil 1. Haven't tried amsoil or royal purple but a buddy of mine told me they used royal purple in their generators in Alaska for major oil companies and seized every one. Switched to Mobil 1 and never had another issue

rotella

My two cents-sense and personal results:
1996 Dodge 4x4 gas motor - 320000 miles with all original drivetrain
2000 BMW M series Z3 - all original drivetrain with 295000 miles
1997 XR400 - 10 years off-road with 2 Baja runs, original motor
2004 KTM450 - 9 years off-road also with two Baja's

All running Mobil 1 - the new 701 will have Mobil 1 in it!

Thanks for the imput guys, I actually found a couple threads of the Fc top end failures a few days ago and now I cant seem to remember where I found them But I think I decided on Rotella 15w40 as I have always ran. In a few hundred miles we'll know if it was a good choice of not!

this oil thing is truly crazy. what about what the manual recommends? These bikes have been built for a long time. The engineers that design these bikes I would think know the best oil to run in them. I would think that whatever they recommend in the manual should work well. I own a 2015 FE350 with 2600 miles and all I have used is Bel ray 10w50 that they recommend in the manual. I hesitate to go against what the people that design and build these bikes recommend.

0w40 is only thinner than 15w40 when it's cold. Same same at operating temperature. 0w40 will flow better through a cold engine upon start-up.

I discovered today that there is now a 0W40 Rotella available. Has anyone used that? Any comments?

I have ran it in a few VW diesels i've owned over the years. Same oil as the 15w40 just thinner at start up obviously. If you're comfortable with the 0w oils then you should be happy with it. I decided to keep running the 15w40 in my new fe501. couldn't be happier.
