Does the New Aeroshell Sport +4 Run Cooler??


FlyingMonkey

Recommended Posts

Maybe I'm going crazy, but I changed my oil a few hours ago with the new (red bottle) Aeroshell Sport +4 formulation, and it seems to run 10-20°F cooler!

 

I flew all weekend in 75°-90°F+ temps, and if I was flying straight and level my oil temps never got above 180-190°.  I could get it to 220°F in a hard climb, but that's about it.  I was not expecting a change with the new formula, but my personal experience so far is that it runs my 912ULS cooler than the old stuff.

There is nothing in the red bottle version of the oil that addresses better cooling characteristics, here are the highlighted differences:

  • It is the first aviation oil in the market that is BRP-Rotax tested and is Rotax Norm RON 424 approved.
  • Provides enhanced anti-wear protection compared to the previous generation – helping to ensure engines reach time between overhaul (TBO).
  • Provides enhanced protection and lubricity for the smooth movement of clutch and gearbox components.

 

However, if you burn mogas exclusively, you can use Mobil 1 full syn motorcycle racing oil 4T which does run cooler by design:

  • Superb shear stability can help resist viscosity shear down in high-performance engines and transmissions 
  • Exceptional thermal stability can help resist oxidation and high-temperature degradation
  • Outstanding protection against wear of engine and transmission components
  • Enhanced lubrication can help maintain maximum power and acceleration over the life of the engine
  • Optimized wet-clutch performance
  • Excellent low-temperature flow characteristics can help minimize engine wear during startup

One other fun fact for owners.  In order to 'evaporate out' water in the oil the engine temp has to get above 220f once in a while.  If always running cooler the water can become an issue, esp in humid and cold climates.

Could you please explain how using mogas affects oil temperature?

 

Didn't say Mogas affected temperature....

 

If you use a full synthetic oil like Mobil 1 4T you MUST NOT use a leaded fuel, like 100LL.  And once you start to use a full syn you MUST NOT return to Aeroshell.

I am with Ian. Your statement indicates that the use of mogas has an effect on temp. whether you intended it or not that is what you said.

 

Where did you come up with not switching to Aeroshell after using a synthetic oil? There were thousands of engines that made the switch from synthetic to Aeroshell when Aeroshell sport 4 became available, and I am not aware of any problems that ensued.

No.  Read it again.  Two sentences. Two distinct statements.  The first sentence clearly states the Mobil 1 has temp control.  Sentence two says you must NOT use fuel other than mogas when using Mobil 1 full syn...

Says who?

 

Does your engine somehow "remember" what oil used to be in it? I'd certainly never consider using an oil that locked me into using it forever.

 

But I'm sure you're wrong again, so no biggie.

Why?

 

 

Because a guy named Kevin said so, the same guy that would not remove 'as recommended by Roger Lee' from fuel lines that you would not endorse.  The same guy that told me that Tom P confirmed that my mechanic was at fault for the damage when Tom was offering to pay a major share of the resulting damage.

 

The underlying guru here was willing to reverse his position to maintain a basis for denying my claim.  He shouldn't be giving out this really strange advice without any reason to back it up.  

 

One of the stupidest things I've ever heard.

I think we may be running away from the subject here.

 

I think we could give 100Hamburger a couple of days to talk to Kevin and have them report back with some supporting documentation which would settle any disagreements and alleviate any more tensions. Instead of relying on one person's word there must have been something in writing some place to substantiate swapping from another oil.

I agree.

This is a pretty lopsided discussion. I'm for waiting for the substantiating documentation i a couple of days. This way we can all get educated if there is something we have been missing. Kevin or 100Hamburger surely must have something they read stating this wasn't a good idea. 

 

If I remember tomorrow I'll give Kevin a call.

 

 

p.s.

I leave town Tuesday June 16th and won't be back until June 30th. If you need me for anything call my cell.  I'll be in Marysvale, UT.
