Engine oil?

I'm at just over 3,500 km. I haven't changed the oil since 1,600 km (first service).

I now want to put in synthetic. Are any 2002 owners putting in synthetic even though they have a catalytic converter this year? I heard the higher phosphorus levels in motorcycle synthetic oils damage cats. And, of course, these are oils without friction modifiers.

Is anyone just running Yamalube? I figure changing it ever 2000-3000 km with Yamalube should be good enough? But nothing on earth beats synthetic.

I hope your not on crack, thats bad shit. Anyway I just switched to the 20w50 amsoil synthetic race oil. My mileage was 3700, I'm at 4000 now and no problems so far except how to keep the front wheel done cause I swear I picked up a couple extra ponies after switching, Amsoil :rock

I'm at 800 kms on my 2002 and I've done two oil changes so far (regular oil). My plan was to change to Semi-synthetic at 1000. I called my local Yamaha dealer to get quotes on Semi-Synthetic oil and they said NOT to put any kind of synthetic oil in the bike until it is FULLY broken in at 10000kms. That seems high to me but then again, regular oil is cheaper, so changing it more often will definitely not harm the bike. I won't get the added horsepower some people claim to have when going synthetic but at least I'll be safe (as per Yamaha). Why risk it, I plan on keeping my bike for a long time. I'll stick with regular oil until 10000kms and change it every 2000 until then. That's my plan, you can verify with your Yamaha dealer to get their feedback.

I know guys who have been using Mobil 1 MX4T 10W-40 and they have ridden thousands of miles with no problems. Go to their web site and read up on their motorcycle oils. It gives far more protection than conventional oil. I would suggest waiting at least 1500 miles before switching to synthetic, but I've heard of guys using Mobil synthetic from day one and they haven't had any problems. I don't listen to dealers any more. Most of them usually don't know as much about bikes as people think they do.

OIL

You know if you drain your oil and fill it back up with water it will run cooler and pick up a few Hp.......just won't do it for long...lol

I have always believed and always will that how often you change your oil and filter is far more important than who's name is on the bottle. I would use a name brand oil that has a reasonable (to you) price and keep it changed often.

As long as it does not say "Joe Bob's oil company" then I think you will be OK.

:hellobye I used Castrol SBK full sythethic.Smooth:thumbup

I have just about 1200km's so far and have yet to change the oil yet.

Supposed to be done with first service the dealer told me:confused:

Should I change the oil right away or should I wait till the first service

I do have a jug of Yamalube 20-40 and a filter that I picked up for later on......

What do you guys think?

Whoa

YamaKid, did you read that off the Castrol Website or something? If not that was pretty good.:D

I can see the long term effects that syntec would have over regular oil as far as wear and tear is concerned. But if you took 2 identical bikes (one with syntec and one with regular oil), and put them through a barrage of speed and dyno tests, I would doubt if there would be any difference. I can see maybe 2 bikes with 50,000 miles having a slight difference if 1 had used syntec the whole time and the other regular.

Oh well, it will remain to be seen. I'll go the syntec route at about 4,000 miles.

the response,in layman terms is:

oil doesnt GIVE horsepower;

different quality of oil will KEEP the available HP level.

too thick can reduce from the base line
too thin can reduce the base line

good text nonetheless.

I was flipping though a recent Hot Rod magazine while waiting to get my hair cut. They did an article about a crate motor they were modifying, making this change and that change and dyno'ing it each time to see the difference. When they had acheived their best dyno numbers, they decided to change to a full sythetic oil to see if any differences were apparent according to the dyno. Think they used Redline oil. Anyway, they immediately picked up something like 12 HP or more on that motor by simply going to the synthetic oil! Pretty cool.:thumbup

LOL!
I wouldnt take that as gospel though...

This is a highly repeated subject and the answers are basically simple.

Friction is drag which absorbs available horsepower. If you use friction reducing oils you will realize higher output levels. These days most oils are awesome compared to oils of only five years ago. You can run any decent oil and if you change it often enough youll be fine. The way you build or run the motor, and the type of oil you use will dictate the change interval.

We all run our equipment pretty hard, so I feel most would agree to change out the petroleum base stuff at 1000-1500 mi. and the synthetic 2000-2500 mi. Cars get more miles because they dont have a transmission whipping up their oil like a blender. Youll always have different opinions on oil type and interval so read up on your preffered product.
Thicker oil reduces horsepower because of the drag on the oil pump, and its harder to pump through todays tighter tolorances. Thinner oil is easier to pump thus yielding higher output. If you use a good quality synthetic oil with a lighter weight you will realize more horsepower "guaranteed". When you upgrade your oil youll also expierence easier shifting. This should tell you something.

Because of the high film strength of todays oils, 20-50 has turned into Grandpa oil except for maybe Harleys.
The old school thinking of using thicker oil to protect better works in conjunction with old technology oil and loose operating tolorances. At startup when your bearings are most vulnerable a thicker oil has a harder time getting to its lubrication points, while thinner stuff gets there quick.
You would be amazed at how light you can go with viscosities and be completely safe.

Sorry, as far as the origional question of Will synthetic motorcycle oil take out the catalytic converter?
Maybe you should have your dealer contact your Yamaha district rep. and find out.

People have been using synthetics in cars with catalytics for years, so use the car Mobil One 10-30.
Ive been using it for years with complete confidence. If not some of that snake oil may just do the trick.
