Hi all:
Question about motor oils. I'm in the process of rebuilding my 302 and,
while the book recommends a detergent motor oil on startup, it suggested
using the maufactrers recommended grade of oil. I was wondering if you
had any recommendations on grade of motor oil for:
Intitial startup
Regular running.
I ask because it seemed to me that the newer cars run a 5w-30 oil to cut
down on friction due to oil viscosity. I am under the impression that
the higher viscoscity slightly decreases mileage and slightly decreases
horsepower. Granted that with a Tiger fuel economy isn't one of the
primary considerations in owning the car, but wondered whether the power
gains and mileage increase might justify a lighter weight multi-grade
motor oil.
I have had a recommendation to just run 20w-50 oil so the pressure stays
higher. Your thoughts on the benefits or deficits of that would also be
appreciated.
Thanks in advance.
Best Regards
David Sosna
