Anyone run Rotella T6 (5W40 synthetic) year round?

Postby IdahoRenegade » Thu Jan 26, 2017 12:17 am

I should know better than to start an oil thread. I really, really should. But here goes.

I run Rotella T6 in everything else I own and am picking up a 2007 Gear Up over the weekend. I like it for my other bikes since it has no friction modifiers, is OK to use with a wet clutch and is motorcycle rated. I also run it in my diesel tractor, diesel pickup when I had one, and my gas cars. Never had an issue with any of them.

I know you're supposed to run a 50 weight (20W50) in warm weather, and that dino oils are OK. I have to wonder, is the difference between a 50 weight and 40 weight a problem in warm weather? Especially given the performance of the 40 weight synthetic. I know a lot of people run it in the winter. I'm hoping it's ok, first because I only have to keep one oil around, because I don't have to worry about timing my oil changes, and because it's a very affordable, quality synthetic, for about $22 a gallon.

So what's the consensus? I did quite a bit of searching on Rotella, but didn't find a firm answer.

eta, bike is used with about 18k miles, so no break-in issues.

I run that in the winter in Wyoming . I will ride down to Colorado or Nebraska to 4000ft and maybe 70 degrees F in the fall and spring... a lot . I have noticed the oil blows by or something when it gets too hot . I won't burn any of the 20/50 during The summer but seems like that 5/40 just 'disappears' when I run it in warmer weather . I'm like you I would like to just have one oil! I was going to try some 15/40 in the summer and see how it does . I am sure someone is going to be negative about this because it is an oil thread . But, I just can't convince myself that it isn't just the luck of the draw if These beasts last or blow up . Time and time again you read about someone who goes the extra mile and never abuses their rig blows up with low miles on it . Where another guy will run it on whatever oil is in sale and 5000 rpm for years without a problem. I can't wait to see this thread roll !

With the frequency of oil changes (1550 miles!) just by a jug of 20-50 Castrol and keep it for the summer. A gallon will do 2 changes. I run Rotella in the cold months, but it's usually due for an oil change around March so I switch back to 20-50

Just changed my oil after about 1300 miles on the 5w40. I had some shiny tinge to it again . This is maybe the 3 rd time in 2 years I have this or at least that I can see when the lighting is right . I can't remember if it was the thin oil and winter riding that it happened last time ... well I'm just gonna ride the $#!+ out of it and if it blows then so be it . I put 5w40 back in . I don't give a $#!+ if it's too thin the 20w50 won't even pour out of the quart in the cold when I change the oil .

Well, that's not encouraging! Rotella for the winter, and 20/50 for the summer it is. 5 qts is cheap enough on Amazon not to worry about it. Was hoping to get away with synthetic and extend the change interval a bit.

Rotella T6 made the shifting 'notchy' on my Yamaha Venture. I have no use for it. In fact I dont like synthetics for the short duration oil changes that our motorcycles are supposed to have. If you plan on riding it in the sands of the Sahara for 10,000 miles with no oil changes, or ride all day in the southern Arizona heat in the summer, then maybe you have a case.

But your only reason seems to be so your garage shelf wont have 3 bottles of analog dino oil sitting there next to the Rotella?

Just FYI: Urals have a dry clutch and can use automotive oils that meet the specs.

Castol GTX is what Ural recommends and I use it. It works great. Why mess with success?

Or so it seems to me...
