Best oil for 1965 Chevelle Malibu L79 327 engine

What is the best oil option for a 1965 Chevelle Malibu SS 327 L79 engine? Previous owner left quarts of Vavoline VR1 30W in the trunk.

Nothing wrong with the VR1 30w for street use, it has everything you need in it for a flat tappet cam. I prefer the 10w30 version.

The 10W30 version is what I use as well. I can get it locally but amazon had a killer deal on it about 6 months ago. Someone here put me onto it.

Google "Classic car oil", and scroll down to the 4th or 5th website, and there is a link to the Classic Car Club Of America. They go in depth why todays motor oil is not recommended for classic cars. An interesting read, but it would take a chemist to understand all the lingo. I does sound plausible though. I have used it in all of the classic cars that I have owned with no problems.

I've spent most of my money on women and guns.The rest I just wasted...

Easy to understand, modern synthetics are not for earlier metalugy engines, they are designed for engine parts that roll, not slide, and hardened bearing surfaces. Our older engines are basically made from metals derived from Silly Putty.

I use dino oils, 20W-50, straight 30.

Dave, I prefer the more advanced metallurgy of bubble gum myself.

I don't know about best but I use Mobil 1 5-30 from Sams club.. I have used this oil for decades in all kinds of engines.. Many flat tappets.. I tried Brad Penn once but it kept foaming and I would get lifter tick after climbing long hills.. I also use Rislone from Shaler.. I add a qt a few hundred miles before oil change time.. I change oil twice a year... I try to park it for the winter with fresh oil...
