Totally agreed. The UOA's on this site for those oils in Motorcycles has been indisputably outstanding.

The OP's Shadow will get along quite nicely on them.

I have a $20,000 Goldwing in the garage loaded with Rotella T 15W-40 and I sleep well at night.

I have UOAs on this site to prove its effectiveness.

I ride in Tucson summer heat ... no worries.

I've been using Rotella 15W40 in my Bandit 1250 for over 9,000 miles..Runs nice and smooth.

Petro Canada's Duron HDEO's carry all three ratings...Diesel, gasoline, and JASO MA all on the same bottle of oil.

The hdeo's will work fine.

Some people just have to have oil with a picture of a motorcycle on it to sleep better at night. Do what makes YOU feel better. If you run amsoil or any other motorcyce specific oil, get your moneys worth. Dont change it out at 2000 miles, especially if you do long highway miles like I like to do.

Is the oil that much better with the picture of a motorcycle on it? I personally dont think so. Is it way more expensive?? Yes.

I used to run the older Mobil 1 mx4t 10W40, heard about running rotella 15W40, it was cheaper, it is still a 40 weight when it thins out at operating temperature, so I am not concerened.

this is going to be my last response to azsynth-----

OK--so it's not $12/qt. It's $12.65/liter (list price for Motul 7100). My Yamaha's owners manual recommends Yamalube ($8/qt at my dealer), and VOAs show it to be nothing special. BTW, one of the reasons HDEOs work so well in motorcycles is that they share many of the same issues of diesel engines i.e. higher temps temps and localized hot spots. Plus no/low moly in HDEOs for wet clutches.

Maybe it's time you read what most of the participants of this forum are saying, rather than reading Hollywood brand oil labels and propaganda.

Show me any manufacturer that does not recommend their own brand in preference to others. Also, show me one manufacturer that says "do not use HDEOs.

I'll tell you right now. You're wrong. I run Rotella T in many motorcycles, ATVs and automobiles. Been using it for years. Dollar for dollar, HDEO's (Rotella in particular) provide lubrication protection more than adequate for small high performance motorcycle engines. I've run 15W40 Rotella T in air cooled ATV engines that performed flawlessly in very difficult conditions for over twenty years. I run it in two Suzuki liquid cooled ATVs, a liquid cooled Kawasaki 650cc dual purpose m/c engine and in a Honda Valkyrie engine. I've NEVER had an oil related engine problem.

You can say what you like about the Hollywood brands. However, when you mislead participants into thinking that the HDEO's aren't good for motorcycles and ATVs I feel it's necessary to challenge your uniformed comments.

Ducati recommended Shell Advance lubricants for the GT1000 in the owner manual. Ducati does not have its own brand and I don't see Rotella or HDEO any where in the manual.

Maybe it's time you read what all of the oil manufacturers and motorcycle makers are saying, rather than reading internet oil labels and propaganda. HDEO will work but it is not the best for motorcycle. I have said it before and I will repeat here for you: go to any professionally sanctioned races and you will not see HDEO or diesel oil in the winner circle. If you are just putting around on your bike then any thing will work, including car oil.

Depending on what we mean by "best," this is a defensible statement. So general agreement here.

That may well be true, but it does not prove the inability of HDEOs to hold up well under even stressful conditions.

That description fits my riding style quite well.

It also fits the riding style of 99% of the amateur bikers on the road today, including those who fancy themselves hard riders of their machines.

* * *
On a more positive note ... I caught a race on the Speed network. It was held in Italy somewhere, but I can't recall the location.

At any rate, I had not before realized how critically important braking ability is in those races. They showed slow motion of the riders coming into the turns, and it was obvious the riders were braking hard prior to the turn. The winner of this particular race -- he won by something like 5 seconds over the second place finisher -- was seen to pull a small "stoppie" braking into a curve.

I'm not a racing expert ... but it seems the key to those races is braking ability into the curves, ability to hold the tire contact in the curves, and acceleration out of the curves. All that is way above my skill level.

Soooooo, whose racing? I don't see anyone asking for oil advice for their Moto GP or Moto Cross bikes. Do you?

Do think that Honda, Yamaha, Suzuki, HD or Kawasaki branded oils are good for motorcycles? It's been proven on this forum and elsewhere that they're not as good as HDEOs. That kind of takes the support from your position. Wouldn't you think?

You're missing the point.

We don't need to spend $12.00 for a quart of oil when perfectly suitable oil is available for a fraction of the price. I find it objectionable that you would insinuate that HDEOs aren't good for motorcycles. You are flat wrong in that regard. You can continue to make donations to the designer oil manufacturer of your choice. I'll spend my money on other things. Like more motorcycles.

By the way, as I've said earlier, I've got thirty years of motorcycling experience with NUMEROUS machines. I was working on motorcycles twenty years before there was internet. My knowledge is gained from experience. Not oil bottle Labels or Hollywood oil propaganda.


I've never had an oil related problem and two of my machines were air cooled and flogged hard for well over 20 years before I sold them. They're twenty five years old now and still running well with their new owners.

I own eight motorcycles as well as two liquid cooled ATVs and tons of other small engined machines. I build motorcycles for a hobby and I don't settle for mediocrity. I think I've been around long enough to know what works and what doesn't. What are your qualifications?

In your mind, how many hundred years should an engine last to prove that HDEOs are perfectly fine for motorcycle engines? If I get that kind of performance with a good quality inexpensive HDEO, why would I spend several times more for Hollywood oil?

Over the years, I learned that some people see the light early on in their lives. On the other hand, some don't even know there's a light to be seen. This message isn't so much for you. It's too late for that. It's for those who are willing to accept logical advice from experienced motorcyclists about what is a good oil for motorcycles. HDEOs are perfectly fine.

That's it!

Those guys are nuts. I couldn't do that stuff to save my life.

But I will say this ... based on what I saw, I can see how such racing would be the very limits of abuse on the bike and the lubrication within the engine. It's not so much the flat-out high RPMs for long durations ... it's the slamming on of RPMs coming out of the curves, over and over again throughout the race.

And I would imagine those guys are shifting the you-know-what out of those bikes throughout the race.

So ... cranking on the RPMs, shifting all the time, slamming on of brakes, rinse, lather, repeat.

My guess is an HDEO would probably survive that for a race ... and has been said, they dump the oil nearly every race, so extended OCIs doesn't really apply.

What's not clear is whether the weight of the HDEO would rob the bike of a fractional bit of horsepower. Someone said they typically run low-weight racing oils ... 0W-20? ... with the full understanding it may not be providing optimum protection, but it may be maximizing power for that race duration.

Believe it or not, power is generally not an issue with modern race bikes. All make more than enough power to be competitive. The key to motorcycle racing success is hooking up all that power to the track. Power delivery is more critical than absolute available power. In line four cylinder race bikes make very abrupt power when the throttle is applied while exiting a turn. This often leads to wheel spin and not gaining the forward motion due to loss of traction. Ducati and other big twins running against the fours are usually given a substantial displacement advantage to be competitive with the in line fours. The configuration of the twin and larger displacement provide a more linear torque curve than the four cylinder engines which makes them relatively easier to manage when rolling on the throttle out of a corner. As a rule, if all other aspects are equal, the twins will win in the corners where the fours will eat up the straights. It takes a very skilled rider to master either of the race bike configurations. You can pretty much bet that the guys running the peaky powerful fours will be working harder to win than the guys on well set up twins. However, it takes a very well set twin and a very good rider to consistently win.

What I find neat about the races with twins vs. fours is the different sounds. Wailing fours and bellowing twins make for quite an entertaining cacophony.

The guy doing the stoppie slowing for the turn was/is American Ben Spies, on a Yamaha R1. A great rider. So, is Mobil 1 15/50 Auto a good oil to use in my relatively low revving speed Triple? It hasn't blown up yet, and seems to be fine.
