Re: IML: What is the best oil to use in a 100,000 mile '59 413 ?

["Henry Blair Jr." <henryblairjr@xxxxxxxxx>]

You are going to get a number of opinions here, but I use Shell Rotella in a grade appropriate for the temperature.  While this oil is a higher detergent oil, it also has the additives that most oils have lost for flat tappet cams like you have in your 413.

I now realize that the problems I have encountered are from changing the oil on my car.  I used a 10w-40w detergent oil and it has gummed up the hydraulic lifters on my car, bending push rods etc.

After having the heads/valves done the culprit was stuck lifters.  In order to not do further damage I will probably use a non-detergent oil which is what was probably there in the first place.  My concern is that keeping a detergent oil inside will only continue to put the grime back into it and cause further problems.

What oil grade should I use for summer driving?  This is the only time I use this car.
