Rotella it is...

Recommended Posts

jbone
Been using Mobil 1 since new , as I do all my motor vehicles. My dad is a long time auto tech and always swore by it and told me he'd beat the stupid out of me if he caught me using anything else. In the FZ, it seemed smooth but felt there was much room for improvement. So, I switched to Rotella T6 last week as a lot of people swear by it, and I gotta say, I noticed a big improvement. I always thought shifting from 1-2 was noticeably less smooth than 2-6 and just figured I sucked. Rotella fixed that issue and then some. Anyway, thought I'd share my experience in the event any of you are having similar issues and consider switching oils.

Diesel oils are fine for motorycles - they are made to run very hot with turbos spinning 100,000 rpm or more in addition to suffering heat from very high compression.

also look on page 97. the oil specifications are on that page and the rotella does not meet either of yamahas requirments for oil types 
https://www.manualslib.com/manual/837941/Yamaha-Mt-07.html?page=97#manual
 
Recommended engine oil grade:
..API service SG type or higher..
..JASO standard MA..

It meet all the requirements.  It's all I've ever used in my Bikes (road and MX), ATV and car.  I even use the use ATV oil in my lawnmower and pressure washer. 
but It your bike.  Use what you want.  I'll stay with the Rotella T6 in eveything

I was running T3 15-40 which was Jaso-ma but it appears shell discontinued the t3 and replaced it with T4 which only lists Jaso-dh2. I'm going to miss my $12+filter oil changes :(

I know a lot of people using Rotella. just because it says Diesel it scares a ton of people away. lots of R1 users even use it for racing.

rotella is API type CJ4. yamaha calls for API type SG. the other from rotella is JASO standard DH2. yamaha calls for JASO standard MA. im not trying to argue im new here but have been down the oil discussion route in powersports many many times. at a minimum you want a wet clutch compatible oil which rotella is not. now i have no idea what kind of consequences will come from using rotella if any but why would you use a oil that is not designed for our engines and doesnt meet any specifications? im not going to argue. just trying to state the facts is all.

Rotella T4 15w-40 and T6 5w-40 synthetic ARE JASO MA/MA2 rated. 
 
I've used both T4 and T6 in all my bikes with no issues at all. Save money and change it often and keep that fresh oil feeling without breaking the bank. A jug of the T4 is like 15 bucks or something at wally world.

ok here is the live web page. the data sheet originally posted was from 2013. on the current web page it does list its JASO MA/MA2 but does not meet the API service SG so even at that it only meets half of the requirements and is not wet clutch compatable.
