Yep....Mobil 1 5W30 plus K&N HP1007 filter.....and yes, I replaced the stock drain plug with the magnetic type (C5) & do ocassionally see "whiskers" on the magnet when I change the oil.

?Wonder what's trying to die. Back in the old days of C-119's, you got some stuff on the magnetic plugs, you got a "chip light" and the engine had to be torn down. 'Course it's a little different for an engine on an airplane; if IT goes bad, no where to "pull over".

Default 5W30 Syn Mobil

Says so on the filler cap...good stuff. However recently I was talking to a Wal-Mart oil specialist, and she said that the new 00-30 Mobil syn is better than the 5W because it makes starting easier and saves on gas and she had a number for that. And that it meets and exceeds all requirements set by 5W30 users. And she said it will become the new OEM for Corvette. Well, whats a guy supposed to do?

There are a bunch of oils that meet GM4718M specs. Okay to use any on that list. GM does not reccommend any oil over another, they just fill the car with Mobil 1 at the factory. http://www.gm.com/corporate/responsi...ngine_oils.pdf

Right now, Auto Zone has a sale. 5 qts of pennzoil platinum and a Mobil1 oil filter($12.99 value) for $29.99

Thanks Craigster, that was some good info!

I did some testing on my own race engines in 2008 and found the Mobil 1 0/30 to be some pretty special stuff.

I talked to Mobil while I was doing my oil development work, and they had said as long as the bearings don't have over 100k on them, the 0/30 will be fine.

I did see about a 1-1.5% increase in power compared to our sponsor's oil, so I paid for Mobil out of my own pocket. And I since have ran it in my Dodge Ram(400hp) with no problems. Seems to increase fuel mpg 1-1.5 also.

Is anyone using the 0/30 in the C6?

Might as well get all the brands in.
I switched to Valvoline Synpower, with comparable wear results to Castrol EDGE. Still use WIX filters.

I stopped at a Wal-Mart while on road trip to have the oil changed because there was nothing else around. The service writer asked me what kind of oil I wanted and I told him Mobile 1. He asked me what that was and I told him "good bye!"
