bike oil vs HDEO

[2000Trooper]

When comparing synthetic HDEO 5w40 to 10w40 synthetic bike oils what advantages do the bike oils have, if any that would justify the extra cost? I mean HDEOs are designed for abuse anyways.

This is on a liquid cooled sv650 if it matters

The bike oils COULD have any of these additional properties:

1. Jaso rated
2. More zinc
3. Moisture/Non Rusting additives for storage.

2k Trooper, what you need to do is look thru all the used oil analysis under the motorcycle oil heading and make your own decision. You can compare how the oils held up under use, then decide which one you want to spend your money on. From what I've seen the only people that benefit from high $$$ motorcycle oil sales are the store that sells it.,,

The SV650 owners manual makes a pretty broad recommendation for oil: SF or SG in a fairly broad range of viscosity, depending on ambient temps.

Buy one that provides smooth shifting, and don't worry, be happy...

Here in Taiwan its now quite hard, (perhaps impossible) to find an SF or SG oil that isn't a motorcycle oil. All available HDEO's are later specs, with less zinc.

I have some old SG Mobil Special 20/50, but once that's gone I'll probably be buying motorcycle oil for my car.

Look for tractor oil, they are SF/CG rated (and CF-4/CG-4)...

both shear at about the same rate.

however with the bike oil you lose 2x - 4x out of your wallet faster.

I wonder if Suzuki and the other Japanese motorcycle makers use that obsolete spec to sell more of their branded oils.

In any case, many riders are using CJ-4 diesel engine oil for many, many thousands of miles with no trouble to the engine, clutch, or transmission.

I know of one Suzuki V-Strom DL-1000 rider, similar engine to the SV650, with 276,000 miles on his engine. He's always used Castrol automotive Syntec synthetic 10W-40. (Suzuki headquarters gave him a new odometer when he ran out of digits on his old one...199,999.)

The old speedo didn't just go back to all zeros?.,,

You crack me up, thanks for keeping it real.

Rotella 15w40 and 5W-40 are both JASO-MA approved so they will not void any warranties. Personally I go with the dino, as I'm not going to leave anything in a shared sump past 3-4k miles anyways.

It also fixed the jittery clutch engagement on my Vulcan over the span of an oil change.

The JASO MA standards both 1 & 2 mean the oil will work in wet clutches.

Lots of folks use a diesel oil in shared sump engines which will work but is not really the best. The detergent package in a diesel oil is far more than you need in a gas engine and the combustion process is different between a diesel and gas engine. This will result in different carbon deposits in the upper cylinders.

Use what you want, but there is a reason for the different oil specs.

One thing about Hdeo oils is they will have a API symbol on the bottle. Motorcycle oils will not.Never have. Which one do you put your faith and $$$ in?.,

T6 is JASO MA approved.

From the VOA's I have seen. There are plenty of super high detergency PCMO gas engine oils out there that clean as well or better than the current crop of CJ4 diesel oils. Look up a VOA of Rotella T6 versus something like Pennzoil Ultra. The big difference seems to be the diesel oils use more Magnesium versus Calcium. But you have to to remember that these diesel oils also carry gasoline engine ratings as well so they are perfectly applicable. The only thing keeping me from using them in my bike is I need a 50wt oil.

Do you happen to sell motorcycle oil,because this sounds more like a sales pitch than anything else.
Please,if you can,show any data that supports your idea that a dedicated bike oil of the 40 grade flavour,lessens wear vs using a 40 grade dual rated hdeo.
I've used most every big name syn in my shared sump bikes and in my experience in real word actual use the diesel oil stayed in grade longer,provided better shifting for more miles than any syn bike oil I ever used.
I've used M1,amsoil,motul,motorex and royal purple and none of them retained shift quality and kept the top ends as quiet as rotella conventional 15w40.
If tested I doubt that those syns contributed to any additional wear compared to anything else,my comments are based on performance in use.
