What brand of oil are you Rotax 912 operators using? Comments?

[Morph]

Most guys I have spoken to use High performance 4-stroke Motorcycle oil

Here is the recommendations from Rotax

I know what type of oil and why we use it, more interested in what actual brands you guys are using. What is considered the best. I use semi synthetic Motul 5100 superbike oil, no problems so far in about 80 hours.

Hallo Mo,

Shell Advance VSX is the one I'am using.
I believe some Bike shops do stock it, else, Aviation Engines is the place to visit.

Shell Advance Semi synthetic VSX as well. About R300/4l.

Will it not be cheaper to drill for oil.

Suzuki South in Plumstead, Cape Town sells Shell VSX4 @ R199.00 for 4/l

A mate of mine who works for Shell advised me to use the VSX 4 which is a semi-synthetic rather than the (more expensive) Shell Advance Ultra 4 which is fully synthetic.

Apparently fully-synthetic oils have a tendency to "sludge" when used with leaded mogas (or Avgas). It seems that most guys run on unleaded anyway, but there are those that use Avgas so I guess VSX 4 is the best all round solution?

Also asked this question earlier, and did a lot of research myself and spoke to a lot of 912 operators.

They all suggested using Shell Advance VSX4 15W-50 semi-synthetic, as most of you suggested as well. Be careful using full-synthetic oils at the coast as it is hygroscopic, and absorbs water!

Here is the latest recommendation by Rotax on Oil and Anti-Freeze dated August 06. The benefit of VSX4 Semi is that you can use both Mogas and Avgas.

So "Mogas", rather stop using Motul 5100, as it is removed from the list, and not Recommended by Rotax anymore (page 5).

Thanks guys, just managed to get online after a couple of days and saw the other posts.
I guess an early oil change is in order.
Anybody want 4 litres of Motul 5100 going cheap???
