What weight
oil is everyone running in the summer.
I used to have a Buick Grand National and would put 10W 30 in my motor and beat the piss out of it with out any problem.
I have also read that some people use 10W 40 and 20 W 50 in the FE 427 motors. My Engine Builder recommends 15W 50 for my motor.
Is there a simple explaination for the weights of the
oil. Or a suggestion what to run in Sunny Florida.
Thanks
