Aircraft Spruce sells Aeroshell Sport Plus 4 for 7.95 a quart, or nearly
32.00 a gal.
I use Shell Rotella full synthetic in my 912ULS, at 17.00 a gal from
Wal-Mart.
That is about half the price of Aeroshell Sport Plus 4, plus there is still
a hefty tab to ship.
I started out using Mobil 1 full synthetic, then Castrol fll synthetic,
Valvoline synthetic blend, and finally Shell Rotella full synthetic when it
came on to the market.
I don't have any scientific observations. Have flown my three 912 series
engines for nearly 3,000 hours. I, honestly, can tell no difference in
performance/service between any of the synthetic oils I have used for the
past 16 years in my 912's.
I use Rotella, organic, in every 4 stroke I have except the Suzuki dirt
bike, Honda Rincon ATV, and Onan 5500 generator, which I use Rotella full
synthetic.
The 912ULS, Suzuki, and Honda Ricon, all use integral
engine/transmission/wet clutch. The Suzuki has 300 hours, the Rincon 3,500
miles, and the 912ULS over 400 hours. All operate perfectly. No problem
with clutch slippage.
Based on the short oil change cycle of the 912ULS, 25 to 50 hours, makes
sense to me to stick with the cheap oil.
BTW: My 1992 Dodge Cummins, which has spent its life pulling a 30' fifth
wheel (and double pulling the fifth wheel and utility trailer with dirt bike
and ATV) for over 367,000 miles, uses Shell Rotella organic oil. Wonder if
it would last longer on full synthetic???

Hi John,
It's been a while.
Just a comment. The oils used in a Rotax should be motorcycle oil because the engine oil is also the gearbox oil like in a motorcycle and has addition additives just for the gears in the gearbox.
Rotax has a new "Line Maint" manual out. Rotax has changed several things and not just a sentence or two. It is on line and they have made some significant changes on the oil and plugs. Actually everyone should download a copy. 91 oct. users can use full synthetic, but people who use a lot of 100LL (more than 30% of the time) should be using a semi synthetic. Dino oil is just barley ok. The synthetics can handle more extremes on all ends of the usage spectrum (i.e. temps, pressures, shears and the ability to stay on parts). Full synthetic will not suspend the lead in 100LL and it falls out in the crankcase and gearbox. The oils I use in the shop for my clients are Aero Shell Sport Plus 4 (semi synthetic), Mobile One Racing 4T (full synthetic) or AmsOil 10-40 winter and 20-50 summer (full synthetic).
p.s.
We do a Fly-In for Monument Valley, Grand Canyon, Lake Powell, Bryce and Zion, but we do it in October and have 30 aircraft that attend. We use Page as a base because of the parking and facilities. Hotels are $49 and food is catered. We do a dam and Antelope canyon day tour as well. They are all LSA except maybe 1-2. This year it is Oct. 14th-18th.

Hi Roger L/Gang:
I have had excellent service from the oils I use in my 912ULS engines.
Frequent gear box inspections indicate zero wear. Can't get much better
than that.
I find Shell Rotella Full Synthetic does as good a job with lead as
Valvoline Durablend, based on my own inspections during frequent oil
changes. I have less lead residue in the bottom of the oil tank with
Rotella than with Durablend and other oils I have used in the past on this
and the other two 912s I have had.
Motor oil does a great job of lubricating gears, whether it says "motor
cycle" on the can or not. I put over 300,000 miles on a Getrag 5 speed
behind my Cummins pulling 5th wheel most of those miles. Not bad.
Recommended lube is 5W30 motor oil. Really thin stuff.
I addressed clutch slippage in my previous post. No problem with Rotax,
Honda, or Suzuki wet clutches.
Until tonight when I read the SI on the Rotax site, I thought Aero Shell
Sport Plus 4 was full synthetic. When I found out it was a blend, 8.00 a
quart seems even more like highway robbery.
I also took note that most of the stuff Rotax recommends to use, or not to
use, is based on field experience, not manufacturers testing. That is also
what I base my decisions on. That is how Rotax established TBO's, which are
recommendations only.
I don't tell others what to use, only share what I do. Other folks can make
up their own mind.
I made it a point to be at the flyin at Monument Valley last October. Drove
down from Moab to spend the weekend and hopefully meet up with you and
others of like interest. However, when I got there, it turned out to be a
powered parachute/para glider flyin. Not a single fixed wing. Didn't know
you all were basing out of Page or I would have stopped in there. Instead,
I left MV and met Mike and Jan Marker at Hanksville, who were camped out at
the airport. Mike flew in with his Murphy Rebel and Jan drove the motor
home. They stayed a week, I stayed with them for the weekend.
Not much fun to go to a flyin without an airplane. If I had had a powered
parachute, I would have had more fun at MV.
Is your flyin restricted??? Do you all camp or stay in the hotel? Is this
an LSA Only Flyin and Around?
We'll be back at Monument Valley next May in the mkIII. Everyone is
welcome, if you can stand it.
Flew in a T shirt this afternoon. Had a ball. Weather was perfect. First
flight with my new ICOM A6. I can hear again. It has much more volume,
plus adjustable volume on the side tone. Side tone that actually works. I
can hear!!!

Oops, didn't mean to inadvertantly restart the oil war with my comments on the Aeroshell.
I was only commenting that my results with it on the first oil change were at least as good as I'd gotten with my other choice that I'd used before (Valvoline synth blend) and not that it was better.
It should be noted that, as far as the API grading system is concerned, both the valvoline and rotella oils actually exceed the Aeroshell (both of those are at grade SM now I believe; aeroshell is SL). Go figure.
All far, far exceed the API grade required by Rotax (SG).
I'm agnostic about additives, as what they are exactly seems never to be specified on the bottle. Only that they're great. The important things are the weight and the API service grade (minus specific recommendations for or against a particular blend by Rotax of course).
I flew a PPC for about 50 hours before having to sell it for space/moving out of TX/financial reasons. They're great fun as long as there's no wind. A 10 to 20NM cross-country in a PPC is a magical experience. Again as long as there's no wind - a PPC would be grounded virtually all the time here in northern NM. As the planes get lighter and slower here, the flying season tends to get shorter and shorter, a small window in the middle of winter. 912 class planes can fly mostly year round plus or minus the bravery and skill of the pilot. Spring and most of the summer are good times for the plane to be down for maintenance, fall and winter are magical especially for trips.
Still trying to get to Questa before the flying season starts to wind down - snowstorms all this week and when the WX is good I'm at the office....

Our Fly-In at Page in Oct.14-18 is open to any one although 98% is LSA. We had 30 aircraft last year and expect more this year. We are always growing. We all stay in a hotel Best Western Arizona Inn for $49 a night. Out meals are catered at the Ranch House Grill. They close and give the entire restaurant to us. We usually have 70 plus people. We are given a large ramp space at the Page airport just for us. Most of the planes are Flight Design CT's, but we have RV's, Rans, Husky, Sirrus, maybe a Cessna. We usually have out of the total maybe 5 other types of aircraft. We do fly-In breakfast in Bryce, we fly south over the Grand Canyon. We all are very friendly not clicks or groups and everyone is very helpful and considerate of the others. We change dinning tables at night to meet people from around the country. It's a great time everyone always comes back plus we continue to grow. I already have 40 rooms reserved at the Best Western. We usually have 5-6 planes show up with only the pilot so there is usually open seats. Lots of wives come. We do a lot of formation flying for some great pictures and video. Weather is better than May because it's not so hot, about 71-74F during the day and 50-55F at night. I have never been around a nicer group of people.
We have another Fly-In May 13-16 at Columbia, CA. We have spot land contest, bomb drop, BBQ's at the clubhouse, fly out breakfast, another fun trip. Again most of these guys are LSA or experimental.
