Is it normal for a V6 2.7 litre at 24,000 k to need to have both the oil pan
gasket and transmission gasket replaced cause they are leaking already?? I
can see maybe one, but both??? even one at that kinda milage is kinda
strange.... thats whats happening on my 2006 Santa Fe... love the
attitude of the dealer though.. when you show yer concern, about it, well
its under warranty..so what ya worried about.. also whats your thoughts
about runnin 5 - 30 oil in that engine instead of the 10 - 30??

The engines are designed to use 5w-20 or 5w-30 oil. There is no
advantage to using heavier 10w-based oils unless you live in a really
hot environment.

I'm told the lighter weight oil is required because the fit of bearings is
tighter than older engines and after some amount of miles you can switch to
the 10W. Don't know if that is true or not.

Your engine/transmission combination is used in several models since 1999,
and the oil pan and transmission pan rarely leak. If repaired properly,
the seals should last a long time.

The issue is the size of the oil passages in the block and head, which
don't get bigger with use.

Actually, I've been told that the issue is fuel economy. The lighter
oils help a little on the EPA tests and every little bit helps.

Some time ago a guy on the chrysler auto newsgroup debunked the myth
about tighter clearances. He posted several key clearances from a 1960s
era engine and a 2000 era engine and they were basically identical.

but my main question was the dealer says that I should be running 10w30 I
wanna use 5w30 or 5w20.. but it was the service manager that last time
suggested I used the lighter oil. so I did. this time when I went the
Service Writer told me that I had to use the 10w30 cause that's what Hyundai
recomends... shrug.. now more confused...

Do you have the owners manual for the car? If so, it should say what
the recommended oil viscosity is in the manual. If not, I'd recommend
buying a manual.

As Matt said, you have to look in the manual and match that up with your
ambient air temperature, wherever you live, to get what Hyundai recommends.

5w20, 5w30 and 10w30 are all acceptable according to my manual, but it
really depends on where you live as to the "preferred" viscosity.

Manual says its OK , Service Writer says its not..

So, do you believe the manufacturer that had 100+ engineers design and test
the engine at a cost of millions of dollars or the service writer that has
an opinion from who knows where?

Generally, you want to use the lightest weight that is acceptable for
your climate. I use Castrol Syntec 5W20 as that meets my needs year round.

Personally, I will believe the person who designed and manufactures the
car over the dealer personnel any day. No offense hyundaitech! Not
that there can't be a mistake in the manual, but unless the service
writer can show me a TSB that supersedes the manual recommendation, I'll
stick with the manual recommendation.

True.

What possible correlation could there be between Chrysler engines and
Hyundai engines? You're comparing apples to oranges.

Two correlations:

1. Most engine makers use the same basic machining equipment and the
clearances really don't vary much across manufacturers. I have service
manuals for everything from VW Beetles to my Sonata and the clearances
just aren't that different.

2. My 2.4L Sonata engine was designed in conjunction with Chrysler.

Next question? :-)
