What type of oil to buy?

[vitrox]

i put synthetic into my r1 at 600 miles, no ill effects except more power.. 8k is way too long for an engine to break in. Ride it like you stole it and its ready to rock in 50 miles. If your rings aren't fully seated by 50-100 miles, then you have a messed up set of rings. I'm going to put yamalube into the fz6r for its first oil change. Its wayyyy cheaper than the amsoil the r1 gets.

I put synthetic into mine at 600 and it runs like a top. I think the idea of putting synthetic in your bike after say 6000 miles is a wise tale. If Yamaha didn't want us to use it in our bikes after 600 miles it would be in bold print in our manual.

I just picked up a gallon of Repsol and a K&N. Gotta do an oil change tomorrow as well as a basic once over with the Lithium lube and torque wrench.

Just got a torque wrench on sale for $27, oil pan and funnel. Now I need to go buy my K and N oil filter and oil.

That's why I'm switching to Repsol. I liked only paying $18 a gallon but if there's a chance that what I read is true, I'd rather spend the money on oil I know will be fine than possibly a new clutch.

That was a rumor spread because the Rotella bottles didnt have the JASO-MA rating on them. They didnt run the testing required because of the Ph levels I believe and everyone thought it was because of friction modifiers not mixing with wet clutches. I can tell you 100% that the new white 4L bottles of Rotella T is JASO-MA certified cause I'm staring right at it. Apparently they went ahead with the JASO testing once they reduced their additives that hurt emmisions systems and due to consumer demand or something like that. I read that Rotella never has been energy-conserving or friction modified. If I find the info from bobistheoilguy I'll post it. Going riding

This last oil change, I put Royal Purple oil in it. The version that's especially made for motorcycles and it's actually been great. But I just found out I get my oil changes for free from my dealership so they might put Yamalube in it(I hope so anyway, and not cheap stuff). My first oil change I put Yamahalube 25W-50 in it and that stuff was actually really expensive. $15 a quart. OUCH!

Holy Cow! Thats expensive even for the semi-synthetic!

I'll stick with Mobile 1 Synthetic at $10 a quart.

There are a lot of good oils out there, some better than others, in specific areas. Any oil designed for a wet clutch application is an appropriate oil. (Meaning automotive oils will not work).

Please allow me to share a little personal experience with you. I race competitive motocross with my race team. I used Yamalube, Mobil 1, Motul, Bel Ray, and Royal Purple in my race quads. We still had to tear down our motors for a rebuild after about 3-4 hard races. I received an Amsoil sponsorship, and was asked why I didn't use it prior. I told them 'it is too expensive to run with all the quads'.

After changing to Amsoil, we tear our motors down after 18-20 races, and replace less than 1/2 of the parts we use to. My race mechanic was so impressed at the lack of wear, and corrosion, that he switched to Amsoil for all the drag quads and bikes that he builds for other people.

We change our oil after every 3 rides or races, whereas we used to have change after each ride or race. The money spent up front, saves 3 times in the long run, if not more.

I have a lengthy SAE test of all the motorcycle oils from research that I have done, with comparisons in many areas. If anyone is interested in this, feel free to email me at teamtrigger525@msn.com.

As for the break-in process, it is important to NOT use synthetic oil during break in, as you want the friction to seat the rings, etc.

So my guy who works at cycle gear sold me Castrol Actevo X-TRA 4T. SAE 10W - 40.

Part Synthetic

Like many others though I asked about full synthetic and he said I shouldn't do it until 8k and about how it isn't until the rings are seated etc.

So how many miles is considered 'break in'?

Also, do you 'break in' the quads with something other than Amsoil? Because its a new engine every time you rebuild it.

I use Yamalube to break in my quad engines. We break them in a little different than most people. We ride them about 60% throttle, staying off the rev limiter for about 30 minutes on a motocross track. The on/off/on/off the throttle, while riding up and down the jumps helps seat the rings. We then check all the bolts, look for any leaks, and they are ready to race.

We will also break in the quad motors on a loaded dyno, just not loading them down all the way, if the weather does not permit outside riding.

Once the break in process is complete, out goes the Yamalube, and in goes the Amsoil. (This process works well for us, each person has their own thoughts on proper break in though.)

For obvious reasons, I do not want to contradict the Yamaha service manual, but in my personal opinion, I broke mine in the following way:

I rode in city traffic, constantly varying the rpm's, but staying way below the rev limiter, but not lugging the motor either, for the first 500 miles. I changed the oil, it was disgusting. I dumped another 3 quarts of Yamalube and a new filter in it, and started a little longer rides, mixing highway speeds and city driving for the next 500 miles, and changed the oil and filter again. The oil was dirty, but not terrible like the first time. I dumped Amsoil in it after that, and have about 1500 miles total on it now.

Keep in mind, that I rode the bike from the dealership to my house (6 miles), swapped out the pistons for some prototype aftermarket piston and rings, changed out the cams, had the heads ported and polished, all when it had less than 10 miles on it. Then I broke it in....
