[R J]

I'm using the auto version of Mobil 1.

Someone will say I'm firkin up my clutch and going to make it slip, I'll just say it has many many miles on it, and it is a stock Honda.        It has enough miles on it, I'm looking for the rivets to go again............   2nd clutch, original and then this one in 240,000+ miles.

15W50 mobil 1  is what I've been using for years in both my bikes. It doesn't have any additives in it so the clutch likes it better. I run mine 5000 miles between oil changes cause it is easier to remember when to change it.

X2.       I just switched from Rotella T Synthetic.  Previously I used Mobil 1 M/C 10W40.  I heard more noise using the Rotella.  Plus with the 5 qt jug of Mobil 1 15W50 it is cheaper than RT.

....okay...so I went to Walmart..(25 miles away)....all the 15/50 or 15/40 they had ...said on the container it was for disel trucks or had a pic of a semi on it....and no Shell Rotella 15/40....does Mobil make 2 different kinds of 15/50 ?

Why the change?

....cuz I used to use Mobil 1 gold cap...then they did away with it....so I started using Rotella....then I saw folks saying they were using Mobil 1 again, and I just preferred that oil...so I figgered Id switch back...

[Robert]

Mobil does make more than 2 types and some I have heard use the suv/diesel one without a problem because most of the diesel oils dont have friction modifiers.

[MP]

The truck ones are OK, in fact the rotella is a truck oil.

Use in my interstate  >>>   Mobil1 SAE 10W-40 MX4T full synthetic motorcycle oil   (Stated to have Optimized Wet-Clutch Performance), no clutch slippage issues, under heavy load/acceleration.

To X-Ring,
I believe the correct description for the Rotella T6 is Synthetic 5w-40w (not 15w).
It says heavy duty motor oil for extreme temps.  At least I hope that is the correct one.
By the way, for the forum members with clutch issues, oil does make a big difference in the "friction zone" of the clutch.Wrong oil will grab with almost no apparent play.

I put some regular old 10-40 in to winter over and the clutch grabbed right now and now with the Rotella, back to normal.

asfltdncr, why don't you read my post again.  I NEVER claimed RT was 15W40.  In fact I didn't list any weight for it as it is only sold in one.    The only oils I mentioned by weight are Mobil 1 10W40 M/C oil and the Mobil 1 15W50 I am using now.

I have tried many brands, but ended up with Valvoline DuraBlend 10W40.
It`s very dark (black) used, so it cleans the engine well. The other benefit is the reduced transmission noice.  

If you want to get an argument started about motorcycle oil, just ask a group of Valkriders whether Synthetic or Dinosaur oil is best for their engines.
You'll find some very, very strong opinions on these issues.
 
The fact is that the choice is yours.
There are very good automotive motor oils that some of my friends use in their motorcycle, while others wouldn't even THINK of putting something in their engines that didn't say clearly on the label that is was created specifically for motorcycles. Some of my friends are completely sold on the fact that synthetic motorcycle oil doesn't break down as quickly and wouldn't use anything else - in their motorcycles. Others choose to stick with the dinosaur oil. As long as you choose a top-of-the-line oil product that meets the specs for your engine, the choice is yours.

[Red Diamond]

Both Rotella syn and Mobil 1 15-50 or turbo 5-40 are excellent oils for the Valk. If you want to hear more whine, use the Rotella. If you want quite and smooth, use Mobil 1.

[PharmBoy]

+ 1 on the Mobil 1 Turbo Diesel Truck 5W40...(or should I have said +2?)

[John U.]

Every time I read a post about oil, Mobil is mentioned by it's weight, 15w50 or 10w40 while Rotella 5w40 is always mentioned as synthetic.
This is not true. Rotella is a highly refined dino oil while Mobil is a true synthetic, though of course Mobil also makes dino oils.
I've tried Rotella in my bikes and diesel truck (which is the stated purpose of Rotella). They both made more engine noise and, though I drained them way early because of the noise, the oil came out with a viscosity more like water. I've never used it again.
I've used a variety of dino diesel oils (15w40) that performed better in my diesel truck at even less cost. They don't have friction modifiers and I've used them in a blend with Mobil synthetic oils in my Valks. The result is good clutch grab and reduced engine/transmission noise.
So is it just price and the word synthetic that has created so many Rotella fans? Rotella seems to be discussed/recommended much more often than any other oil and I am at a loss to understand why.
Just my 2 cents.

John, Rotella T6 5W40, in the blue jug and bottles, is a full synthetic just like Mobil 1.  Mobil is dino oil just like Rotella T in the white jug and bottles is.

And with a Budweiser beer can for an oil filter cover.

I am running the Mobil 1 15w50 automotive fully synthetic oil that comes in the bottle with the grey cap.  My local Wal-Mart doesn't carry it and I have to go 30 miles to another to get it.Whatever you buy, make sure it doesn't say "energy conserving" in the little digram on the back of the bottle as those oils have the friction modifiers that can harm your clutch.

[Crazyhorse]

Used Mobil 1 red cap, then gold cap and Rotella T. Back to Mobil 1 bike just seems to like it best.

I used Mobil1 15W-50 gold cap until they quit making it, simply because the previous owner of the first Valkyrie I owned recommended it.  He was very knowledgeable on the Valkyrie and everything else he recommended proved to be good advise.

I now use the Mobil1 15W-50 gray cap...it appears that many others on this board do the same.

Marty, I'm not a chemist so my opinion is based in part on what I read from reliable sources. My understanding is that Rotella 5w40 "synthetic" is a highly refined mineral oil.
"Hydrocracked/Hydroisomerized = API Group III base oils. Chevron, Shell, and other petrochemical companies developed processes involving catalytic conversion of feed stocks under pressure in the presence of hydrogen into high quality mineral lubricating oil. In 2005 production of GTL (Gas-to-liquid) Group III base stocks began. Even though they are considered a synthetic product they are still mineral base stocks and counted as the mineral part of all semi-synthetic lubricants. Group III base stocks [with certain amount of mixture of PAOs and esters and Group V] are considered synthetic motor oil ONLY in the United States. Group III based lubricants are not allowed to be marketed as "synthetic" in any market outside of the USA."
I've read similar explanations of group III oils from many sources, I don't think there is any question that what is called Rotella synthetic is a group III dino oil that has been hydrocracked.
Is it as good as Mobil synthetic?   For my money the answer is no, but of course there is a price difference. Your experience may result in a different decision.
It seems beyond doubt that motor oil has improved greatly over the years. Any good diesel oil (no friction modifiers) will probably do a fine job in a motorcycle.

[Robert]

I agree with John on this one and its the same with Castrol I did use the Mobil one motorcycle but recently just switched to the Redline 20w/50 and there is a difference. Not only with price but also with noise and just the general feel of the oil it seems to be much better. I will do a oil analysis and see what it comes up with and report. Like said so many times before you seem to be able to use anything short of cooking oil and have the Valk do ok so a really good oil is just overkill.
