5.7nhigh millage what oil do you use?

What oil do you use in a old high milage engine ??

 

[Randy and Easton]

This is what Easton uses. He follows Derek from Vice Grip Garage so that’s where he came up with the choice. I think he adds some Lucas oil additive of some type as well.

Magic oil. Lol

But if you can't find any, the Rotella is good. I like Lucas in the large car, but personally have had mixed results with gas engines.

Red valvoline semi 5-30 sometimes only because it's easier to find.
sometimes conventional 5-30.
valvoline. I used to run quaker state but they sold to pennzoil and I switched.

The weight the engine was built for.
5-30 in my engine. Yours may be 10-30.

All that boogie man heebie geebie bull ish about zinc this and zinc that is pure hyperbole.

I’ll assume you posted this in jest. For the rest of the crowd, while ATF may work in transmissions and transfer cases and serve as a good injector cleaner for old diesels, there is no plausible reason to add any to ANY engine’s motor oil. Unless your goal is to turn good oil into bad and wear out the engine quicker.

I run atf in engine oil all the time.

I've been using a half quart of ATF in my engines for 30 years with no problem, plus they're clean enough to eat off of inside.

It's kinda like zinc in the oil. You'd think if it was so important my engine woulda blown up at some point in the last... 35 years without it. All that conventional motor oil doesn't seem to hurt it none. LoL

Wanna line em up? How mush money you got in your pocket?

Rusty's on a roll. Where does he find this stuff?

What-u-got oil. Any oil is better than no oil... when you are runnin' on empty. But really, usually the store brand, unless something else is on sale. 10W-40 on a tight engine, 20W-50 on an old classic, a work truck or race car. 10W30 on modern daily driver LS motor.
