i used Castrol Full Synthetic 4T motorcycle oil and could definitely notice a smoother shifting, plus got a 6 pack for 44$ including shipping off Amazon. Everyone has an opinion on what type though, im sure if you search oil you will get a million threads.Hi guys,
I am coming up on my first oil change. I want to use rotella t6 5w-40 synthetic oil. Is this a good option, or are there better oils for my bike out there? Thanks
I use Mobil 1 4T Full Synthetic which is very similar to the Castrol only more expensive and can definitely second much better shifting. Mine is 10w-40, but like brands everyone has different opinions on weight.i used Castrol Full Synthetic 4T motorcycle oil and could definitely notice a smoother shifting, plus got a 6 pack for 44$ including shipping off Amazon.

Agreed, manual says 10w40, but think there is another weight listed. It depended on ambient temp. I run 10w40 in some chilly 40 degree Temps up to 100+ with no issues. Have to say that switching to full synthetic made a huge difference though.Weight should not be a matter of opinion. Bearing and ring tolerances are set with a certain viscosity of lubrication in mind. There are only a few weights that should be used and changing is determined by the conditions (oils perform differently at different temperatures). IIRC yamaha has 10w40 spec'd for MOST conditions, but I would have to check.
Rotella is a good oil; I personally use Amsoil in all of my vehicles as they are a sponsor of mine (auto racing). Anything good quality and meant to work with a wet clutch should be fine, but using the correct weight is important and you will see no benefit from straying, only increased wear over time due to poor lubrication.
(should be noted before anyone tries to say otherwise, thicker oil won't penetrate bushings/bearings/rings as well, so too thick is just as bad as too thin.)
i cant remember what the Yamaha manual said I put in 10w-40 but in my cruiser the other option was 20w-50 if you lived in high temp areas. Since the Castrol Vtwin specific oil was 20w-50 and I do live in a hotter area I went with that.Agreed, manual says 10w40, but think there is another weight listed. It depended on ambient temp.

yes, as a matter of fact it can go stale! gotta taste it to see if its good or notWhoa, wait... you're supposed to CHANGE the oil? Why, does it go stale or something? Every time I check mine there's lots in there, so it's not like it's going anywhere...
+1 I went to Mobil 1 4t full synthetic as well at first oil change and am also changing to Castrol 4t full synthetic. $20 less a case and all reviews for both are 5 star. Many went from Mobil 1 to Castrol for same reason. Think it's like $43 for a 6 pack case. Mobil 1 is $63ish. Figure with a k&n 204 an oil change runs about $34 roughly.I swapped to Mobil 1 full synthetic at the first 600 mile oil change, and then swapped to Castrol synthetic at the next one cause it was on sale. I noticed a difference when I first went to synthetic, both oils feel about the same.
Just get the cheapest quality synthetic you can find. Just make sure it's 4-stroke for bikes.
