TELL ME WHAT YOU THINK .
If you bothered to actually read it, you'll see where it says the tests were run by independant SAE ( sociaty of automotive engineers) facilities.I like oil test comparisons but really that comparison and test is put out from someone who sells amsoil. You think they would say hey our product is crap. I'm not saying amsoil is bad just saying i feel it would be very biased.
Castrol does make a MC oil. It is the Castrol 4t 10w40, 20w50. Not sure they make a synthetic version though. I will say it is the cleanest oil I have poured out of a bottle.This post will turn into a religious post on this subect, All I can tell you is that a lot people use Amsol oil and stand by it Golden Spectro and Rp oil. Pesonaly I would say do your own math and come up with a conclusion. But I picked RP because my Mech uses it have been using it for years in all my sports bikes so I said hey it works good in this I'm going to put it in my. Vtwin. My mech races has some records and if your in the area his name is know Gleen stickels have brole some Records in the area motorcyle and snowmobile...yes. snowmobile....I agree with everyone else all oils are not created equal... but Mobil 1 I wouldn't evnen run that in my car.... Personaly if castrol made a MC oil I would be sold. So do some serches and come up with your own conclusion... Ask around mike bikes a 06 may be when it 10 years old if I still have it you can ask me how she is holding up and what oil } have been using. Untill then like some one said on this form the oil use today is better than what was used 30 yrs ago ...so use what you want.. hell try supertech(synthic) from walmart I just think you will change it more often.Buddy of mine just used valvoline 20/50 and I know they have a record of mixing a good oil. And he Rides.... JMTC
I've been riding motorcycles for 46-years and have used about every brand of oil in my motorcyces and I can tell you that I haven't noticed any remarkable differences between any of the different brands that I have used. A lot of what's posted is just preceived differences. Some like one brand of oil because they buy it at an auto parts store vs. Walmart so they think it's better or one brand costs more so it must be better. Your buddy races so what he uses must be the best. In my opinion, most all motorcycle oil will work well in your motorcycle if you change as often as you should and you ride it the way it is built for.
I've used Amsoil synthetics in all my vehicles for 25 yrs. I have used the extended drain intervals and have put over 100K miles on several of them. I run my bikes for 10K between changes and change the filter at 5K and top it off. If I buy it new I wait till the 3rd service to change. I ride hard an put lots of miles on my bikes and I wouldn't use anything but Amsoil in any of them. I have put over 40K miles on each of 6 different bikes in the last 10 yrs and not a single problem. Several were still running like new with close to 3 times that when I sold or trade them.
In my long and varied experience with Amsoil I have found it to work exceptionally well. I use it and all of their products in my $50K corvette Z06. It just works.
I don't have hardly any pics of it and none on a web host so can't paste in a PM. Besides it's for sale and I sould let every body know.:droolegasus i did like yopu untill I read your post about haveinga Vet z06 now im hateing... lol I love that car still working to get one. Pm me a pic.And if you run Amsoil in that with no complaints I guess your right stick to it.:bigthumbsup:
How did he measure that. If he was going by an oil temp gadge that's a good thing. It means the oil is pulling more heat out of the engine, which is what you want. That means that the engine componants that don't benefit from contact with the coolant are running cooler because the oil has absorbed the heat. The only true way to measure oil cooling effectiveness is throught the coolant temperature, without a thermostat, which regulates the temperature of the engine. If it is an air cooled engine you need a head temperature gadge to measure it.I run Mobil 4t 10w40 and a local member ran the same and then tried Amsoil 10w40. With the Amsoil in it, it runs 10 degrees hotter. Don't know why but it does. But he told me that he is going back to Mobil 1 4T 10w40 on his next oil change.
