Amsoil vs Mobile One

[resurection]

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.

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.
