from full synthetic back to Victory oil ???

[jaysonL]

Would that cause any problems ? I know at one time, that it was said that once you switched to full synthetic you shouldn't switch back to conventional. I remember someone telling me it was hard on seals and various delicate internals. But I know today there are numerous syn/blends on the market. So, has anyone done this, or have any real knowledge of whether it may be a bad idea ?

Most everything you have heard about synthetic oil is a myth. Synthetic is perfectly compatible with petroleum oil.

No problem...

I thought Victory 10-40 was a semi-syn anyway.....no?

This is true...

Guys stick with one oil. Do Not keep switching.

Your girlfriend might care what lubricates her, but rest assured your engine does not... as long as it is lubricated.

Victory oil is a syn-blend but I have to ask why you are switching back? What are you switching back from?

You are describing a classier girl than I am acquainted with.

As far as the engine goes, I tend to agree. Peeps get way too anal about the earl in their pearl. Recommended viscosity and detergent rating are both worth maintaining since oil pumps interact with varying types to different degrees of efficiency. Will using a different viscosity or detergent rating motor oil lunch the mill? Not in the short term for sure. Any motor oil beats no motor oil.

The flip side is that if you want to minimize variables then using the same product over and over is in keeping with that effort.

What I don't know is what effect various non specified motor oils will have on Victory clutches. I'm just too green with this brand and looking forward to the learning curve in the primary. As opposed to the engine which is metal, polymers and some standard fibrous gasket compounds, all common materials and all forgiving of motor oil flavors, I don't know what effect non specified oils will have on the fibrous components of the clutch. I know what I can get away with in a Harley primary but the requirements of the Victory clutch are not identical. Although the basic execution is the same the requirements for viscosity, the effect of oil mixture on the fibres under varying temperature and pressure conditions and who knows what else may make using a specified product necessary to clutch performance and/or longevity.

Until I have put my grubby little hands all over the Victory clutch I'm inclined to be particular with what I coat it with.

Millions of single oil, wet clutches in bikes outside the Harley and Ducati lines.

Simple answer is don't use oils specifying "friction modifiers." Outside of those, I've use numerous cheap auto oils over the years and never had a problem.

Dry clutches SUCK. They are easy enough to change, but they burn plates so quickly and easily and they have a tendency to moan and grab and slip, there is just no reason...save that Duc folk like loud clutches to save lives...
