when is it time for syn?

Postby hotflash44 » Wed May 10, 2017 7:45 am

Hi,guys thinking on switching to redline synthetic, but the bike only has 1800km its a 2016 gu. I don't want to switch until its fully run in. At what mileage is it safe to make the conversion?

I don't use synthetics in any of my bikes but they are all a bit old/long-in-the-tooth. Personally I'm surprised the new one's don't already come with syn in them like pretty much all new cars and bikes.
Not sure if it matters when you change over? For older motors there was and is always the belief that once you go syn you can't go back. I don't know if that is true or not?

Castrol has a High Milage blend of syn & dino that I started using on a BMW r1100rt years ago after it broke 60,000 miles. My only foray into syn. with a bike.

Our cars a 2013 Jeep and 2017 Lincoln both came from the factory with syn so that's what they get at oil changes. I really don't see any difference but obviously the more modern engines must do. Your Urals engine design ain't exactly anymore "modern" than my 2007 or older models even with the EFI slapped on it. Personal preference.

Thanks, as i under stand the vehicle world, other than Ural uses syn oil, but the tolerances and machining are modern. I think of the Ural as i would a 1960 ford. they all needed the careful 500 mile break in to do the final machining that the factory didn't. your right i hear that Ural may start sending the bikes here with syn oil? I don't want to introduce syn oil to soon, if the 2016 engine isn't broken in, as some say the break in process will stop when syn is added.

If you must, probably wait until most of the fuzz stops collecting on the magnetic drain plug. That should be a sign the engine is pretty well broken in. I run syn in the winter because it flow easier in freezing weather, makes starting less of a chore. But in the summer I go back to good old cheap Castrol 20/50.

A Ural engine finally gets broken some where around 10,000 kilometers. Many of us that have owned Ural that long will tell you that someplace around 10,000 kilometer their bike seemed to get into it's happy zone. On my current bike it was closer to 15,000 kilometers. One day you get on to go for a ride and it is WOW is this the same bike I parked yesterday? I don't know for sure what happens or why but it sure is a joy when it does happen.

Unless it's specifically designed as a syn 'break-in" oil. Conventional syn is pretty slippery due to the additives(detergents?) I suspect break-in designed syn has less detergents? On initial break-in you want some scuffing to occur to seat the rings properly. On a new motor of any brand I wouldn't switch from dyno to syn motor oil till I had at least 2000km on the motor. On my 06 R1200GS, BMW recommended not switching to syn till 6000km.

Using regular oil is good enough. Just don't forget to follow the recommended oil change interval.

If it helps, my dealer uses semi for the first two changes, because he says full synth "is too good, you need to rub the rough spots off first". Full synth after that. I.e. 3rd change onwards. Made sense to me anyway.

Friend Tony at Racewayservices put synthetic into my rig at 500km. I went back to mineral at 2500. It took until 18.600km after the second engine seize that the engine started to come free- Since 21.000km you could say the engine is running well.
At now 37.500km I still stick with mineral oil in the engine for to keep motor brake, as the experience for those 2000km with synthetic showed that the bike would push downhill like a 2 stroker.

As long you feel with each oil change that the bike performance improves stick to mineral oil in the engine. Probably 15.000km or more will pass by then.
For transmission and FD I use synthetic with the result that Sophie marks her terrain from there.
