How Much Oil Do you Use?

[Alan Cordeiro]

Derek,

I will guess that you are talking only another year or two, perhaps
another 20 or 30k miles. That' why I suggested you jsut add oil.

Plus, I know first hand what it takes to do a head job...

OK OK....go ahead...flame me

Alan
197k, one quart per 5,000 miles
