That's disconcerting.

It's only 'disconcerting' if you forget to look at the dates of the lawsuits (1995) and the type of oil used (OEM'd as 'copter tranny oil).

This is quite old news among pilots and FBOs.

In my mind, the people who blew their aircraft engines by using an inappropriate oil got what they had coming. Teledyne/Conti are very very specific on oil recommendations and nowhere in the books is any kind of reference to this specific Mobil product.

Yes I do own an airplane, have for 15+ years (3 different planes, currently a Cirrus SR22), and use M1 products in the engines. But I use the *correct* products and have never had a problem with premature wear or sludging.

Noooo.... because A.) those are AVIATION forums... and B.) Just because Mobil 1 was being used, well lets just say that what the aircraft use & what our vehicles use are totally different gradeIoils.
in conclusion: no it does not apply to us. (unless you own and fly your own aircraft)

you own an SR22??!!?!?! care to fly that baby up to frand forks one day and let a poor kid who's never flown anything faster than a seminole have some fun? ;)

A sweat bird she is.... Never thought I'd enjoy a fast single as much as I do this one.

If you *really* want to try an SR22, enter this contest:

http://www.cirrusdesign.com/hhonors/

I also see that the UND Aerospace Foundation is now an authorized FTC for Cirrus. They probably have a few planes by now espec since CD intro'd a new TKS anti-ice (not a full deice but a safety system) last fall.

My a/c is currently 'down' getting some Vari-EZ style winglets installed and the whole body smoothed and repainted. Hope to have it back up by March 1st so that I can get the bugs shook out before I head to Fun 'n Sun in April.

yeah, UND has buddied up with CD and offers intro training on the SR20. as i understand it, when you buy a Cirrus, Cirrus sends you a big packet of systems info, POH, etc and then when you show up to train, you take a basic test to make sure you know the basics of normal and abnormal procedures. then you get 7 lessons of training 3 ground and 4 flights, including a long cross country. what i've heard is that CD had to provide training programs such as this to keep the insurance rates on their aircraft from being exorbitant because the planes are so high performance and the avionics are so advanced. do you know if that's the case? and where do they send you SR22 guys to train?

The aviation issue aside, it is a synthetic , and acts like one

All the while, Mabil continued to promote synthetic with an extremely aggressive advertising campaign that made grandiose claims for the product: "a cleaner engine with little or no sludge, a 200-hour oil change interval, up to 30% less oil consumption, 10-15F cooler CHTs, and up to 5% fuel savings." Many knowledgeable engine people considered some of these claims to be exaggerated commercial puffery, and most considered Mobil's suggested 200-hour oil change interval to be insane. But owners lined up to buy the synthetic at eight bucks a quart

Could this be of concern with Synthetics oils in cars

1. first the background as quoted

Quote:
It's important to understand the mechanism at work here. Synthetic oil is composed of long, smooth polymer molecules that don't have all the little side branches that petroleum polymers do. This makes them extremely slippery and gives them excellent lubricating properties. Synthetic oils also lack the "light ends" of petroleum oils that can break down under extreme heat and create varnish and carbon deposits.
so far so good , but


I quote again :



But it's those same smooth, ultra-slippery molecules that give synthetic oil its Achilles' heel: the inability to hold lead salts and other contaminants in suspension. The synthetic oil molecules are simply too damned slippery to hang onto such contaminants, so they settle out of solution and form sludge deposits, particularly in areas of oil stagnation .

lots of it in some cases (read the article)


And then this about low use engines ,


Quote:
). The oil film on cylinder walls tends to strip away during periods of disuse, resulting in cylinder wall corrosion and metal-to-metal scuffing at the next engine start. Hence, low-utilization engines tend to wear cylinders faster.
So have the synthetics we use in cars been tested for this kinda stuff >?

(and I do not want to base the result on what one person thinks)

unless you have a phd in oil technology...?

then quote the study to back it up and disprove this...

thats all that I would want.


;)

Thanks for the info. I'll look you up when I win the vacation!
Think they'll let me sit right seat - I'm not IFR rated,just single engine land VFR...
