I heard something weird lately and i wanted opinions from experts. Is it true that when an engine had synthetic oil that it is not good (see bad) to put it back to ordinary oil ?
If yes couls someone explain me exactly why ?

Subject: Beware synthetic oil

Beware of synthetic oil, it can do terrible things to you and your
beloved vehicle. It will not only leak out of your engine faster
than you can put it in, but it will also cause your oil filter to
clog and implode, dumping debris and dirt into your lubrication
system. It also will make every part of your bike permanently
slippery because of its linear molecular chain dispersion action.
Then it will leak onto your kickstand causing it to retract
automatically, dropping your bike on the ground! But that's not all...

Synthetic oil will round off your gears and spin your bearings. It
will also splatter onto your seat causing your girlfriend to fall off
in the apex of a turn and she'll never ride with you again. Synthetic
oil coats your sight window and your timing window with a whitish
pro-emulsification additive that is both non-removable and highly
corrosive. Synthetic oil will completely leak onto the ground overnight
and your dog will drink it and die.

Synthetic oil will wear out your tires and make your battery leak. It
will give you the desperate need to urinate after you put your full
leathers on and then jam your zippers shut. It will contaminate your
gasoline causing your bike to stall on railroad tracks and accelerate
uncontrollably near police cars. It will make it rain during rallies
and on weekends. It will lubricate your timing belts causing them to
jump teeth and break your valves to bits. Synthetic oil chemically
weakens desmodromic valves and causes the clearances to change every
six miles. Then it melts the black soles of your riding boots right
before you walk across your new carpeting.

While riding past groups of attractive women it will cause both of
your handlebar grips to slip off at the same time so you smash your
windscreen with the bridge of your nose. It also causes your swingarm
to crack, your studs to break, and your rotors to warp, and then it
voids your warranty by changing your odometer reading to 55,555. It
also dries out your wetclutch and wets your dryclutch. It makes your
clutch slave cylinder seal fail in the heaviest traffic on the hottest
day of the year while putting an angry wasp in your helmet for good
measure.

Synthetic oil hides your 13mm socket and puts superglue on your
earplugs. Synthetic oil will scratch your faceshield and make your
gloves shrink two sizes night before trackday. Synthetic oil stole
your neutral and sold it to the Chinese for $1.25. Synthetic oil
will make you grow a tail. Synthetic oil will write long crazy
e-mails to your Internet friends and then sign your name at the
bottom!

I've gone back and forth on my 180,000 mile Audi - no issues.

Warren - excellent post!!

Sharkbody

I say we get rid of the stuff altogether. G

That's not the worst of it, there's also the "DYNO CURSE"!
The spirit of the dinosaurs will destroy your bearings if they're allowed back into your engine after you've been disloyal and used synthetic oil.

Sharkbody

Come to think of it. My car hasn't been using any at all. G

Great stuff Warren...........can fully relate to the m/cycle slant.

I'm going back to Castrol R............good old castor oil when men were men and m/cycles leaked like sives.

DANdeMAN

I went back to dino juice 20W50 oil presure is better 2.5+bar at idle insted of 1bar and cams sounds smoother. Less oil leaks to...

FlyingDog

Absolutely nothing wrong with doing that.

About What Warren said plus I have heard this story the other way around.
That ordinary oil leaves deposits in your motor and then switching to synthetic oil will loosen all this cr*p which then blocks important parts of your oil system.
Sounds unlikely to me but what do I know.

I believe there is a standard that the oil has to meet for interoperability with other oils. Most of your name-brand oils (Castrol, Valvoline, Shell, Mobil, etc.) all meet this standard and have a seal on the bottle accordingly. I believe John Veniger works for an oil formulation company, and he gave a very informative talk about oil at the Frenzy 9 before I got banned from driving through PA.
