Which is a better oil?

I'll have oranges. You can have apples.

Spectro.


Cant stand amsoil. Nothing more than Castrol in a fancy bottle and costs $5 more.

I've used both and like Mobil 1 a little better simply b/c I can get it almost anywhere and don't have to order it (father in law is a dealer) when I need it.

Rotella T

And I prefer Delicious apples, but I can't eat them with skins anymore because of my allergies.

rotella t????. lol  i like mobil one but i use problend additive. lately trying royal purple. supposed to pickup hp on a dyno.

No joke.  If the weather is good enough, I'll break in on SAE30 Rotella T, but in colder weather, 15W40.  Then move to Rotella T synthetic 5W40.

you need to try the problend it's the best snakeoil i've found. used to sell it a few years back the only thing is the wet clutch. it's a coating i think it has a lot of zink in it. i know it works though

Mobil 1 MX-4T improved trans. shifting by 20%, and is good with the clutch.
Tried Motul, not as good in my opinion, back to Mobil 1.

Rotella T is what we run race or street .
Please worry less about oil than starving your pick up .
I cant remember last race motor that had oil related failure.
The stunt bike squids doing wheelies starve the motor of oil and burn Babbitt's
(crank bearings) And kill 2nd gear.
Bikes at the track may have pickup issues on breaking ,that doesn't last to long .
Long stopies, long wheelies are your only oil concern.
I've seen 10 street bikes have oil trouble maybe 1 race bike!!


Racers care enough to change there oil .
I don't think the type much matters

I use Elf Moto 4 XT Tech

100% synthetic base
10W-50
100% PAO
JASO MA
API SG
Anti-clutch slippage
Very high endurance performance

I have an Elf connection in St. Louis. If anyone is interested.

Silkolene

Those oils are so dam much money .
If you change the oil often your wasting your money .The big come on with sny.oil is the time between changes!
I know I've read all that shit , about why you should us it .
If I was selling it I would brag it up also.

Syntech!!!! 

The big selling point to joe consumer is time between changes. The typical cager driving to and from work is actually in the severe service catagory, racing is well above an beyond any catagory. Further our engine oil, in most cases, is shared with the transmission. I run 9 race weekends a year and change every other weekend. That's $125 worth of Amsoil a season vs $45 if I went to the parts store and bought good dino oil. $80 is more than worth the peace of mind I get knowing I am doing the most I can to protect the  internals against the abuse I dish out every weekend. Hell, I pay more to get in the gate than I spend on amsoil each weekend. The old saying holds true, "Pay me now or pay me later".

I like Amsoil, I have seen it demonstrated on the timken machine against a good dino oil and the difference was truely amazing. I can't do justice to the test in words, you have to do it yourself to understand.

Anyway that's my 2 cents.

i go two race weekends in my 748 mainly to check the screens then pour it in the 900 then it goes in my service truck from there it leaks out on the highway. pissing off everyone on 2 wheels that rides in the middle. the good part it doesn't smoke near as much as organic oil.

My general view is buy who is supporting you, so I use Silkolene products.  But....any good oil should work as the other folks have said, race bikes get changed so often that the oil should not be breaking down.

I do one other thing that I believe helps and tells me more about whats going on in the engine.  Every 2 or 3 oil changes I take a sample and send it off for Oil Analysis, I get a nice little report back that tells me what is in the oil and if I have any parts/bearings wearing etc....  It costs 15 bucks a shot if you buy it in 6 packs.  The first report won't tell you a whole lot but will be your baseline.  Make sure you tell them everything when you send in the sample, oil type/brand, fuel used, etc..  They will really give you alot of detail.

Money well worth it.

I also do my diesel truck 1-2 times a year dependent on use.

1. That's very cool.  I sent for a test kit. 
2. Look at all those metals.  No wonder we can't eat fish anymore!

Repsol rocks

Yeah, if you run U4 or other you will get really really high levels of lead, which can seem like a bearing, so getting a good base line, running similar conditions is the best way to get a good result and to really tell you whats going on in the motor.  Seems like a good way to help make that "do I need a rebuild or not" kind of decision.

  Amsoil 20W/50 Racing Synth. raced successfully in BMW, Honda, and 2 Suzukis. Drain after a few weekends and put it into the wife's car. Great shit.

  Rotella Synth in a pinch.

I use Spectro (can't remember the name but it is the synthetic blend type).. works good and I can't justify using full synthetic as I change the oil after every race weekend.

Haven't really seen a real difference in oils personally, but if someone has done some testing I would love to hear the results....

I've run Silkolene for years now.  Companies like Silkolene, Motul and Repsol have both the research capabilities and involvement in racing at the premier levels that allow them to both develop and continually improve their product.

The Silkolene importer told me that a racebike running their Pro 4 Plus oil should only need to be changed every four weekends of sprint racing.  I still change every weekend if I'm running endurance and I now go three weekends running sprints.

I sell all three brands in my shop but I don't generally waste any time trying to get customers to switch from automotive oils or other brands of motorcycle oils.  It's like talking religion, people have too much emotion invested in their choice to objectively look at alternatives.  The biggest danger to the average bike is not the brand of oil, but the lack of proper maintenance or the owner's attempts at working on their bike.
