    For a stock 305, WalMart 10w30 or 10w40. I've ran it in some of my older vehicles, it meets all manufacturers specifications, never had an oil related issue. No need to waste money on the high dollar oils.

    After reading and researching all over on this deal, I just gave up and bought a three jug case of the Lucas 10-w40 Hot Rod oil on Amazon. Seems like nobody can agree on anything when it comes to oil for the older motors, and the oil companies won't give straight answers. "Meets or exceeds" don't mean a thing on this deal.

    yeah tom, agreed, it's all opinion. I like Lucas products, the trans. stop-leak saved my butt in the mountains drivin' a subaru. I guess the bottom line is to change it like you're s'posed too. \m/

    To reduce camshaft wear, flat tappet engines require an oil with about 1500 ppm zddp, more than is commonly available in oils presently produced. The anti-wear compound, Zddp, content has been greatly reduced since 1994 as it damages catalytic converters.

    (zddp is zinc dialkyldithiophosphate)
    (ppm is parts per million)

    If Mobil 1 has no ZDDP, then don’t use it or your cam will go south.

    But we need to consider the engine setup and mileage. Old old motor with sagging valve springs and well worn in parts would probably be ok with used french fry oil. I can remember tearing down old small blocks with lifter bottoms you could drink coffee out of, lifter valley was full of sludge, and the motor ran fine. A fresh build with a modern cam grind and all new machine work would really need that barrier lubrication to survive I think.

    yeah, to zinc or not to zinc, being the question. always been my teaching during break in it's a must. especially with flat tappets. change it afterwards to whatever temperatue recommendations are and just keep it fresh. I've poked holes in the return passages, changed the oil and kept on..
