I think you will find that Rotax specifies an API-TC spec. oil. The TC-W,
WII and W3 oils are designed to be used in outboard motors where
temperatures are a lot lower in the cylinder head. The oils you mentioned
are supposed to have more ash than the API-TC rated oils. I'd use the
Pennzoil two stroke or the Bombardier XPS mineral. Actually I just changed
my 582 over to the Bombardier oil.

| Subject: | Maximum Continuous RPM for a Rotax 503 |
Hi,
I am planning to join a group of dedicated (i.e., crazy) UL/LSA flyers who
want to fly over 8000 foot mountains going from California to Arizona in
planes with 503 and 582 engines. Since I will need to climb as fast as
possible for 20-30 minutes at a time, I would like to know the maximum
sustained RPM that my 503 will tolerate.
I know that the Rotax manual states that you can run at 6500 all day but
should not run at the maximum allowed RPM of 6800 for over 5-minutes. My
problem is that the maximum RPM on my my Challenger II long-wing aircraft is
only 6200 due to its prop pitch. Does this mean that the maximum sustained
RPM also goes down? If so, is this decrease in sustained RPM in proportion
to the max speed (e.g., 6200/6800x6200 resulting in a max sustained RPM of
5926)?
Thanks for the help,
Les

Thank you for your answer Noel.
Guess I have to get back into boating if I want to use this oil.
Rgds,
Les
