I totally agree there about oil viscosity. When I first moved to NC the only 
job I could find was at a Ford Quick Lane, an oil change joint mostly, and 
they only had 5w30 and 10w30 in bulk oil. Every vehicle that came in got 
that stuff, no matter what age or mileage. I brought my '79 Cevvy dually in 
to change the oil and my foreman freaked out at me putting in 15w40 saying 
only diesels run oil that thick. Needless to say I broke as many of his 
rules as I could there without getting fired in the interest of doing things 
right. I even put almost every wheel on with a torque wrench until I was 
told to never take it out of my tool box again. Job only lasted a few months 
anyway until I moved to managing the parts department, then found myself 
back on P-cars shortly thereafter.
