1979 Corvette

[flatlandtacoma]

My father-in-law just bought a 1979 Corvette(!) Said he always wanted a 'vette and now he has one. Only 41,000 miles on it.

He is not mechanically inclined at all and I will probably change the oil and filters and whatnot for him. I don't think he will be putting too many miles on it, probably 5k or less easy miles per year.

Of course it has a 350 small block V8. I have no idea what kind of oil has been used in the past. Given the above what would you put in it for once per year oil changes?

amsoil atm 10w30 and the appropriate amsoil oil filter.

Valvoline MaxLife dino 10w30 or 10w40 and a Wix or NAPA GOLD filter.

I'd probably go with Castrol GTX, 10w30. If you look in the handbook for this car you will see that it can run, with good grace from GM, on pretty much any oil you can find, including a straight 30 weight.

Castrol Syntec Blend 10W-40 and an AC Delco filter.

Any good dino oil

In my 1980 Firebird FORMULA with the original unrebuilt small block V-8, I've been using just about any brand name dino 10W30 for the past 27 years(1 oil change each summer).

MaxLife 5w30, AC Delco filter.

Interesting. That is the first recommendation for 5w30. Why 5w30?

The small block Chevy will last a long time with pretty much any oil you put in it.
