i see all these threads about people using 10w40 and 20w50. however the manual says to use 20w40 or 20w50. is it ok to run the 10w40 in my 2010 R1 or should i stick with 20w40? i use mobil 1 in all my vehicles but would have to settle on another brand as mobil doesnt make 20w40. thanks.

cool. i found some 10w40 4T at advance auto for 9.98/qt and judging by the prices online going at around 13.50, i think $10/qt is a good deal.

Are you 100% sure it says 20W-40 and not 10W-40?

My '09 manual says 10W-40 or 20W-50... There's no reason for Yamaha to change their mind unless it has something to do with the CCT. I use 10W-40.

20W-40 is rare/impossible to find. Yamalube doesn't even make 20W-40 anymore that isn't marine oil.

im 100% positive my manual says 20w40 - 20w50. i even asked my wife to read it to me. i used mobil 1 in my honda cbr1000rr and i plan on using mobil 1 in my 2010 R1. i also use mobil 1 in all my other vehicles and i have for the last 6-7 years. i just like it for some reason. anyways, ill take a picture of my manual to document my info and see if it coincides with anyone else on here.

i dont know what the deal is. its definitely strange and a little frustrating not knowing why. im going to use the 10w40 4T mobil 1 oil when i do my oil change. thats what ive used in previous cycles and i dont know why they would change recommendations without changing engine specs. it just doesnt add up. if they found something out midway through production of a model, you think they would let the rest of the people that have already purchased know whats going on.

I have an 08 r1 and the bike dealer told me to use 10w 40 so I did only to find out immediately afterward that it specifically calls for 20w 40. Should I swap it out? Also they said it calls for 3 1/3 at n I'm above the sight line quite a bit. Bout the very top of the site, will this cause harm to my bike? Thanks for reading

i think the 10w40 is fine but make sure its motorcycle oil. 4T racing or yamalube or the honda oil or whatever. as far as level, it is important to have the correct amount in there. either drain it all into a clean container and refill until it is at the full line or drain and put new oil in.

think i can just drain a bit and stop it? i prolly have only ridden it about five miles. Ok and so my next question is can i drain the oil just leaving the bike on the kickstand. Obviously i can cause thats what i did but maybe it doesnt all out without standing it straight up. That would explain the extra oil in the bike. let me know what you think, thanks!

oh and its deffinately motorcycle oil. all of the information and product was advised and givin to me buy my local dealer, (M.A.P.). Thats why i dont i understand why i had to much oil and the wrong called for weight.

i just did my oil last night. while i had mine on a stand, i think i would have benefited from taking it off the stand, and leaning it to the kickstand side a bit to get the little bit left in the pan. thats what side the drain plug is on. yes you can change it on a kickstand. its just easier to put it on a rear stand for maneuverability. as far as oil, ive used mobile 1 4T racing oil in almost every motorcycle ive owned, 3 to be exact. my book says 20-40 or 20-50. im not sure about the yamalube discontinuation but the 09 is the same as my 10 and they use 10-40 so it shouldnt be that big of a deal, atleast to me anyways. one thing i did do was change it with yamalube 10-40 for the 600 mile change for break in, and ill change it again at 1000 -1500 miles again with another round of yamalube 10-40. then at around 3k miles ill be switching over to the mobile 1 4T racing synthetic for the remainder of the engines life. just personal preference due to mass reading and research.
as far as draining a little to lower the level, it can be done but gets VERY messy Very fast trying to put the plug back in while oil is draining out. thats y i said just drain it into a clean container and refill to proper level. give it a shot and if it doesnt work, u can just drain the whole pan. good luck bro.

Has it occurred to anyone it may just be a misprint too. after all they screwed up big time on rear sprocket nut torques on the 04-06 and never changed anything.
Not giving a recommendation for temps below 50 degrees is a major oversight, or maybe the new ones aren't meant to be out of the garage when it's chilly :lol

you should be able to Download a pdf of the manual from yamahas website. google 2011 R1 manual and you should be able to find a link. ill do the same.

just looked and yamaha only had up to 2010 owners manuals. i guess a call should be in order after all.

I don't see what the big deal is. Run 10W-40 unless it's summer in the desert then run 20W-50.

I wonder if they changed it because of the CCT issue, thinking that a thicker oil and startup would alleviate the CCT noise? I tried 20W-50 in my '09 and it made no difference in the CCT noise.
