I have been fighting oil usage in a 2d gen HEMI for over 2,500 miles. The first suggestions were intake sealing. With the help of Proformance gaskets, I am confident that the intake is sealed. Still I have oil usage, (one quart in 100 miles). The funny thing is, my buddies don't see oil smoke while following me, the pipes and plugs are a light tan.
While at the Nats, I talked to several "celebrity" engine builders and several HEMI owners. The consensus is: change from 10-30 to 20-50 oil. I have been using Brad Penn. One owner told me that 18 YEA,RS AGO
he changed to 20-50 and has not had a usage problem since.

Does anyone have any input on a HEMI that is just driven? My engine is set up with "loose" clearances, forged pistons, Teflon seales etc.
