Is it good stuff or not so much?
And can anyone tell me....does using the 3/4" longer filter present any other problems with clearance or the like?

|chazzman||Everyone has their opinions and having used synthetics for over 20 years I am certain that is the way to go if you want longer engine life, better fuel mileage and performance. The synthetic coats the lubricated parts and greatly reduces wear on initial start up, that is where you get the most engine wear anyway is on start up. The engine also runs cooler with the synthetic. I switched from mobil 1 to Amsoil about 5 years ago. There is a Goldwing with 350,000 miles with no engine work that has been running Amsoil 10W40 since new. The 10 in 10W40 is the weight of the oil on a cold start. The 40 is the weight after the engine reaches operating temperature. Where I live 10W40 is appropriate year round. The oil change is the most important thing you can do to protect your investment. I am certainly not an expert on oil by any means but I have been in the Automotive business my entire life and seen engines destroyed from sludge build up. I run my automobiles 5000 on Amsoil between changes and could easily go 10,000. I like to change oil filters at 5000 so I just go ahead and replace the oil at that time. I get excellent pricing on Amsoil so it's not bad. I do the same on my Goldwing but the rider with 350,000 miles has changed his oil and filter every 10,000. I usually overkill so 5000 suites my taste. I rode Harleys for a few years and the dealers would always argue with me on synthetic saying that it would cause the roller bearings to slide instead of roll, what a crock. Harley enjoyed selling dirt cheap crude oil with the HD logo and made millions. When the word came out on V twins saying how important synthetic was for the hot running Harley's and all the mags starting posting results, how convenient it was for Harley to stamp the HD logo on semi synthetic oil. Amsoil smokes the Harley oil and now most HD riders run Amsoil.|

|Lukejt||Check it out, page 45 in the Versys service manual explains that too much slack in the clutch lever will cause slippage. Correct gap is 2-3mm with the lever just taking up the slack. It's not the oil, in my case.|

The truth is that plain-jane oil is perfectly fine as long as it (and the oil filter) are regularly changed/renewed. Synthetic blends also provide excellent lubrication.
We tend to forget that there are hundreds of reciprocating and load-bearing surfaces in a motorcycle engine. Unlike cars, motorcycles also rely more heavily on oil as a cooling medium. In shared-transmission sump designs, the motor oil takes care of all those tranny gears, too, and that is the main reason why I run semi- or full-synthetic designed specifically for motorcycles in such bikes. In bikes where the engine and transmission are separate, I use plain-jane oil in the motor and the typically recommended hypoid oil in the transmission. Each oil is designed for a different, specific function and going fancy with synthetic oil provides dubious benefit. When the oil is doing as many things as it needs to do in the Versys, for example, I am willing to pay a bit more for oil that makes the transmission shift slicker and suspend clutch contaminant better.
As far as the original question is concerned, I do think that a motor as tightly engineered as in the Versys should get a few thousand miles on it before going full synthetic. Going straight to full-synthetic might preclude some surfaces from swapping out those crucial molecules that comprise a good bearing surface. I also want the transmission to wear a bit to get looser and thus shift better. I am already prolonging that by using a synthetic blend, but I also really want the benefits of using an oil like Motul to start now.
The oil brand and type game is just that. Yes, synthetic is better than regular dino oil, but just how much better and whether it is worth triple the price for a quart is a contentious issue.
Sorry about the long post. No more oil talk for me! Time for a scotch and a nice video.

Lukejt, if your clutch is slipping with OEM dyno oil, then I have to ask, if your clutch is properly adjusted. You should have a little bit of free-play in the clutch lever. If you don't have this free-play then the pressure plate springs can't apply full pressure on the clutch pack. Worth a check.
|07-13-2008 09:22 PM|
|Lukejt||It's been doing it since it was new, but I'll wind up changing the oil all the same. It never slips on it's own, the clutch keeps slipping for half a second or a second once the clutch lever is released if I'm hard on the throttle.|
|07-13-2008 08:46 PM|
Absolutely. If it's automotive Mobil 1, change it before more damage is done and you might salvage your clutch. Mobil 1's Racing 4T 10W40 would be compatible with the wet clutch.

Personally, I wouldn't wait until the next oil change. If your clutch is slipping, you should probably switch oil now.

I'm finding that my clutch is slipping WAY more than I would like. However, it did this before I switched to Moblil One with the factory or dealer installed oil. I don't know if it's the oil, or the clutch, but I can fully release the clutch and with a lot of throttle dialed it the clutch will more often than not continue to slip for a second or so, it's a real bummer. However, sometimes it grabs like it should resulting in a bit of a wheelie. It's very inconsistent and I don't like it. I dunno. It's right up there as the #1 thing I don't like about the Versys (while I LOVE the bike) with a lack of feel for the brakes being the 2nd issue (I'm getting used to these as well, but will be switching to a more aggressive brake pad in the future).
I've used Mobil 1 in every bike I've owned (5 in all) and never had any clutch issues, but I've read all the JASO info and realize the friction modifiers may present problems for certain motorcycles. My next oil change I will use Rotella, as this is what I use my other vehicles, except the dirt bike which requires 50 to 60wt oil.

Invader's info is good news to me. The wet clutch is the separating factor between Automotive Oil and Motorcycle oil. When the oil industries starting adding increased percentages of "friction modifiers" some bikes started to experience slipping clutches. Motorcycle specific oils had reduced friction modifiers in their formulation. I use the Rotella in My ST1100 and have found it to be excellent. I will say that the Amsoil did provide smoother shifting than other oils.
Filter construction has long been a topic of discussion on ST forums. Several people over the years have done extensive research on various filters quality of construction and filtering ability. There is much more to a filter than rather it will fit or not. Bypass valve, drain-back and several issues concerning mesh size of the filter media and square area of the filter media are important issues.
If you are willing to pay extra to switch to full synthetic then I would suggest you pay for the OEM brand name filter as well. One of the major advantages to using full synthetic oil is that it holds up longer and thus allows longer change intervals.
If you are really serious about oil qualities, I suggest you contact an organization like Blackstone Labs and get your oil tested. Based on these tests you can set up an informed change interval based on facts and not on a Lawyer's Liability Interval.

[QUOTE=danomar;6131] I just switched to Motul synthetic blend 5100 10W/40 and will go full synthetic in a few thousand miles.
Is it preferable to go to a synth/dino blend before going to full synthetic?
