Here's an easy one. My 912's almost ready for start and I'm sure at
least Lowell knows the answer to these difficult questions:
* How much of what kind of oil? (I realize installs will differ
slightly, but realistically only a little.)
* Where's the best place to get it?
* How much of what kind of coolant? (Pretty sure it's Evan's but don't
know if there's a cool replacement out.)
* Where's the best place to get it?
Thanks all!

I just received a case of Aeroshell Sport Plus from Aircraft Spruce. It
was back ordered and took about a month to get here - About $119 plus
shipping for 12 quarts. It seems highly recommended by the Rotax
community and is reported to be formulated specifically with the Rotax
912 series in mind and to help with the lead scavenging needed when
running 100LL Mark uses a Honda motorcycle oil with the gear additive.
The gear additive is the prime ingredient as some motorcycles use the
engine oil to lubricate the transmission as well which is the common
factor.
As for as the coolant. I think the main issue here is to use a coolant
that is Silicate free. As far as the Evan's coolant is concerned, I am
personally not a fan at least as far as our application goes. Some
Rotax installations have cooling problems and require a water free
coolant to prevent boiling with the high temps they frequently see. I
just checked the current Service Bulletin and that is the implication
there. In our Kitfox installations, that is not a problem. I was
talking yesterday to a friend with a Model IV and 912S and he is talking
about a thermostat because on a recent cross country flight he saw
cylinderr head temps as low as 105 degrees (Far from the need of a
waterless coolant as Rotax describes them). I personally use Prestone
Extended Life. Not because I think it is the best necessarily, but
rather it was convenient and meets the specs as I understand them.

Lowell,
Thanks for the reply. How much of each for a full change?

My memory is not always accurate, sometimes remember things that didn't hap
pen.=C2- But, it seems the evans coolant was removed from the approved li
st about a year ago because of unsatisfactory results in the field.
=C2-
As for oil.=C2- There is a list of approved oils which is updated periodi
cally, probably on the rotax site.=C2- The basic theme is motorcycle 4 cy
cle oil with gear additive.=C2- Mobil 1 gets high marks if less than 10%
use of 100LL.
=C2-
Anyone else have similar recollections.

Updating the repair status on N195KF: Welding complete.=C2- Spring Gear b
ack order 13 weeks, Purchased tube gear from Roger Standley of the list for
back up; thank you Roger.
Last coat of polyspray applied this morning, will start on the polytone tom
orrow anticipating a week or so of spraying, masking and color trim.
=C2-
The big delay will no be the fiberglass work.=C2- A bid to repair the thr
ee lower pieces was $1350, slightly more than total replacement of all five
pieces of the round cowl and radiator shroud.=C2- And almost double what
MacBeans need for the three lower pieces.=C2- As an aside, they have bee
n very supportive of=C2-the repair efforts.=C2- Will probably try repai
r on my own with some local support to see if acceptable examples can be co
mpleted.=C2- My glass experience includes farings for the windscreen on R
V9 and light weight skin of mahogany ply kayak.
=C2-
Will keep you posted.

Oil quantity?=C2- I find the 3 quarts usually blows off some excess, thou

asured care.

As others have said I think Rotax removed Evans coolant from the
approved list. Our New Zealand Rotax agent recommends Aeroshell Sport
Plus 4 oil and Castrol Radicool 50/50 coolant. The ratio of water will
depend entirely on how cold it gets at your place. Quantities are about
3 litres of oil and the same of coolant but will depend on your type of
oil cooler and installation etc. It is very difficult to see how much
oil you have actually got in the tank. The small dipstick hole gets oil
coated in it and new oil is almost invisable. After you add oil to the
tank let it drain for several minutes before checking the level and
spray your dipstick with mat black paint. After you are sure how much
oil is in the tank clean the paint off again. Follow the Rotax
proceedure for putting 5 psi of air pressure in the oil tank to
initially prime the oil system. The whole system holds a lot of oil and
you need to top up the tank when priming. And don't forget to check
the valve lifters.
