There are 15w-50 oils for both superbikes and cruisers, what would be the difference?

I know cruisers and tourers require long distance riding at high speeds.

Superbikes on the other hand are revved higher for shorter distances.

How is this related to select the correct oil for the same grade?

prolly about the same + i use real synthetic PAO 15-50 in my 106" victory + 650 cc bmw thumper + 895cc triumph bonneville. for my weather in Pa it works well, hotter climates can use 20-50, 15-40 diesel is quite popular as well. most any decent oil is fine if changed regularly. air cooled bikes usually need thicker oils + many crotch rockets with some water cooling use 10-40's quite a lot.

Long distances at high speeds doesn't mean the engine is doing a whole lot. With a cruiser you might be turning 2500-3000 RPM. Even a superbike you're not turning that high of an RPM overall unless you're absolutely flogging it.

The hardest thing on a motorcycle oil is the shared sump, in terms of shearing. I don't know what bikes other than Harley that are cruisers that split the engine sump and transmission in two separate units.

20w50 V-Twin Mobil 1 went over 5000 miles in my ZRX 1200 shared sump this past summer and held grade right in the middle of a 50 weight. Can't ask for any more than that. Mobil 1 10w40 4T was the oci previous to that, almost 5,000 miles and held just below a 40 weight in grade by less than half a point. 4T starts as a light 40 wt so relatively speaking shearing was not worth mentioning.

With that said, Mobil 1 20w50 V Twin does show thickening in air-cooled non-shared sump engine such as the Harleys. Never been proven harmful but no one has a real explanation for it.

I'm really sold on those two oils. I would like to try Mobil 1 15w50 another time, however my UOA's show noticeably lower zinc and phosphorus than what Mobil claims they put in that oil. As well 15w50 did shear down to a 40 weight. Granted I like mobile 10w40 4T however if I put in a 50 weight I would like to have it come out a 50 weight. If I want a 40 weight that's what I'll put in it and the Mobil 1 4T pretty much does that.

The 4T at the time showed less zinc vs 15w50 by Mobil specifications however tested at higher zinc vs 15w50 in my UOA's. Even though wear numbers are basically no different between the oils, shift quality did hold up better with motorcycle specific versions.

There are others. Off the top of my head, BMW, Indian, Some Ducatis, one older Honda model had a separate gear case, Victory, and others
I don't know details about might have separate transmissions.


My 2¢


There's no such thing as:
Too big of a battery,
Too large of a gas tank,
or too loud of a horn,
or too bright headlights.

Victory/Indian (Polaris owned) all have shared sump motors.

WITHOUT a shared sump, my Burgman sheared 10W-40 to 10W-25 in 3000 miles.

I switched to 15W-40.

And older British bikes.

I said "I don't know what bikes other than Harley that are cruisers that split the engine sump and transmission in two separate units". The operative term is "cruisers". BMW and Ducati really don't do cruisers however many newer BMWs have wet sump systems now. I wasn't thinking of scooters as cruisers either... Victory used and Indian still uses a semi dry sump, which shares the oil between the transmission and engine but compartmentalizes it and it flows between them, for a simple way of saying it. It is still subject to the forces of shearing of a fully shared sump.

There is little difference between Veedol Auto and Veedol Super 4T oil
to make any appreciable difference in engine longevity let alone the
difference between a Sport and Cruiser oils except as always the
limited quantities of motorcycle specific oils cost more for the
manufacture to produce and market... Technically speaking either
Veedol 15w50 will meet and exceed your mileage expectations...

Yeah that's a good post. The OP was asking if there's a difference in similar weight oils that would make him choose one or the other for a different type of bike and engine combination.

What is Veedol oil? Never heard of it, where does it come from, who makes it for them, etc?

I maintain a synthetic, like the Mobil 1 MC specific oils, does maintain shift quality for at least 5000 miles in a powerful shared sump engine. Only basing that from my personal experience, there may be conventional oils that do as well for some folks. I love to hear about those oils.

With respect to the oils in the above post, what would be the rationale for a much lower TBN on the MC specific well? That does seem to be an appreciable difference. As well, it shows a marginally higher viscosity despite being of the same weight yet the pour point is lower.

Their starting TBN of 6.0 is lower than either of the Mobil 1 motorcycle specific oils after 5,000 miles in my engine.

My post was not related to Veedol oils specifically. The confusion comes from the fact that my motorcycle requires a strong but basic oil.

1. It is a 500cc torquey single which makes its power below 4500 rpm. Usually 500-650cc bikes have a twin cylinder where each cylinder would be 250-300cc but making power at 8000-10000 rpm. That should definitely have a bearing on the oil we use.

2. My bullet has a shared sump vs. a seperate sump on many British vintage motorcycles. Thicker oil is definitely needed. But I had best experience with a thin Elf moto4tech 10w-50 followed by Veedol take-off 15w-50 mineral followed by others including shell advance4t full synth. So, a Veedol mineral has better shifts than a Shell Advance Ultra synthetic which is surprising. The only explanation is that Veedol says that it is specifically made for my Royal Enfield ( meaning additives?). Shell has active cleansing agents which may have removed the necessary sludge from gaps rather than smoothening the drive.

So this led to me asking whether there are different oils for superbikes (I used Shell advance Ultra Ducati edition ) vs. Veedol Take Off which is a basic mineral oil but maybe with specific additives. But then how did ELF moto4tech full synth made for sports bikes provide me with the best experience?

Those are some really good thoughts and you put a lot of time into what you posted. I think what you have seen and what makes sense overall, is different oils regardless of whether they are made for a specific style bike or otherwise, can work differently in any given situation.

We can't answer that question because none of us here know the exact compositions of any of these oils - the only people who know are the ones who formulated them. And they're not talking. What the label or their Web site says is mostly marketing babble, take it with a shaker full of salt.

For a low-revving air-cooled single, I wouldn't go lower than a 40 viscosity grade. Since you're in India, you can ignore the W number, as that pertains only to subfreezing cranking performance.

Try different oils and use whatever you feel works the best. Change it on a regular basis and you'll be fine. Bonus points if it is inexpensive. And be aware that oil formulations can change over time.

Chemically speaking a 10w is a new and improved formula over a 15w...

API ranks the first number 10 and the letter W from the newest to the
oldest on its ability to lube your engine during critical start up because
the most wear happens during startup before pressure is establish...

0W

5W

10W

15W

20W

If you wish to employ the latest in oil companies technology then you want an one with an API
low number rank...
