Shell Rotella Snythetic 5w40 oil in CB1100

[Ulvetanna_imp]

I am quite sure Shell Rotella T will not hurt your motor. Too many people on too many forums using it with no adverse effects.

I don't care what any one eldse uses in their motorcycles, their business. Shell, Amsoil, Honda, Yamalube, oem filters, K&N filters, Bosch filters, they all have their advocates and detractors but bottom line is it's more important that it is changed on a regualr basis than what it is changed with or to. I am not personally aware of any catastrophic engine failures due to oil or oil filter types in the last 45 years.

I can tell you up until Dec 31, 2006 Honda recommended 10W40 for all of their 4 stroke motorcycle engines. As of Jan 1, 2007 Honda has recommended 10W30. Why that change of recommendation and why on that date is any body's guess. Some has said it's for emissions, or for gas mileage. Who really knows.

All I know is that for my 2006 ST 1300 Honda recomends 10w40 and for the 2007 ST 1300 which is identical other than paint, it recommends 10w30. My 2014 CB1100 DLX they recommend 10W30. ALL Hondas since Jan 1, 2007 they say 10W30. Why? who knows. They do make allowances in the owners manual and service manual to allow 10W40.

Bottom line, I recommend that you use what you have faith in and are comfortable using.

Yep just make sure it's the correct grade and JASO-MA. If in doubt use exactly what Honda specifies.

Forgot to mention Yamaha will now provide 20 years or 100,000 miles warranty if you use only Yamalube oils. Maybe there is something to the OEM recommendations.

Nope, it's a money-grab and a marketing campaign, plain and simple. This tells me that engine longevity doesn't depend on oil brand. Simply follow the manufacturer's recommended maintenance schedule and you'll be fine.

It's funny that nobody agonizes over the brand of piston ring or big-end bearing in their engine, the wheel bearings in their front hub, the bolts holding their cylinder heads on, or the circlips keeping their transmission together. It's simply because oil changes are easily accessible by the consumer and the marketers know we're easily influenced and easy prey. It's the same with aftermarket exhaust systems, air filters, spark plugs, tires, clutch plates, brake levers, foot pegs, etc. We conveniently ignore the components we can't get our grubby little hands on, like critical engine internals, but we're all experts on consumables or the stuff we can tinker with. Marketing!

Marketing! I very much agree with you about guys fretting over all kinds of things like oil, filters, O2 Sensors, and the like, whilst paying zero mind to all those inaccessible components. Out of sight, out of mind.

I don't see the Yamalube Warranty as a money-grab though. Yamaha just took first and second place in the French MotoGP, so I expect they know something about performance and durability.

Secondly, the Yamalube warranty costs nothing, and the rider gets a 20-year power train warranty just by using the Yamaha product.

I was choosing Yamalube for years because of the quality; one thing a guy notices is shifting ease, and Yamalube was at the top of the heap when it comes to shifting.

Now, I realize that if a guy is shifting at 1500 RPM perhaps he wouldn't notice, but snapping quick shifts up and down at high RPM, one can tell the difference. Honda oil is the same, very good. I choose OEM oil over Motul or any of the other brands because they work well in the transmission. That's really the only indicator that's palpable. Kawasaki, Honda, Yamaha oils.

The Yamalube warranty is a cool perk and I'd have no issue signing up for it if I'd just purchased a new Yamaha. 15,000 redlining miles on my current Yamaha and a very, very clean bill of health so far. My reflash bumped the rev limiter up 500 RPM, engine seems to be loving it.
