Hello all, I have a 2009 repsol 1000rr. Had it 2 years now. I done last oil change and used motul 5100 10/40 as I used it previous R1 and was advised not to use fully syn. Bike burns no oil. I only use bike as a week end toy. Might do a couple of track days later this year. Seen posts on here ref 10/30 silkolene pro4. I would like a smoother gear change. Should I change or stick with what I am using. Not bothered on cost as its only changed once per year.
I am not sure on the oil grade to be used, but personally, if you are doing trackdays, I would advise on changing the oil more than once in the year. At the least, change it after every other trackday, but ideally, I would drop the oil after each one.
Hey mate give the Pro 4 a go you won't be disappointed but if you don't like it you can always go back to Motul but remember our bikes should be running 10w30 oil! I'm not sure why people advise on running semi synthetic maybe it was advised whilst running in the engine of the so-called oil burners and it stuck! I Donno but it's the grade & viscosity of oil thats really important! Anyhoo try Silkolene Pro4 Energy 10w30 let me know how you get on!
Well, going to give the pro 4 a go. As you say if I don't like it I can always go back. Any advise on where to buy it. Got my genuine oil filter yesterday so don't need one of them
I thought there was engine flushes needed between switching from synth to semi synth and back again, so I was told, but of course that could have just been bike shop bull sh1t! They said it was critical to get every drop out before using the other, they also said the same between dot 4 and dot 5 brake fluid, could be the same crud again of course? I honestly have no idea but would like to know either way on both counts?
You really should never use any flusher... It's not needed. You can mix semi and fully synthetics just fine. Just use a high quality fully synthetic in the bike and you'll be fine. You don't need to change it every other track day either ... That's a waste of good oil. A decent ester based oil will have a good molecular base which will not start to break down for thousands of miles. So much bullshit when it comes to oil.
I buy mine from my local bike shop they order it in for me I got some a couple of weeks ago it cost £52 for 4ltrs of 10w30 energy! You could probably do the same or chance it of eBay
I use Castrol 10w30 fully synth on my 08 blade. Just did a 900 mile round trip to th TT and it's used about half a cup of oil, and there was plenty of hard riding in there. £31. Delivered, it's on ebay.
semi synthetic was a marketing ploy introduced many years ago. The producers put in 5~10% synthetic into mineral and called it semi and sold it as over twice the price of the mineral but cheaper than fully synthetic. To Joe public it had the word synthetic and was cheaper than the real stuff. High profit margin means it get recommended a lot. The motorcycling fraternity has been very much behind with synth oil and there is still some traces of psychological barrier for some. I've been using it since early 80's (cars only) when Mobil rally 1 was the only one available in the uk. I agree with changing the oil more often than once a year if you are doing track days. I would also go for 10/40 or 10/50. With track days and 10/30, I would change the oil every 2~3k miles. either way, full synth all the way
