Your engine is not a 2-stroke or a diesel. You don't put oil in the gas.
What you are doing is an unnecessary waste of money and resources.
If it was a "great product" and "good for the engine", new car manufactures would use it. None do.

there's a sucker born every minute. if the jeep is making substantial metal on metal noises there is no fix. take it apart and repair it correctly, otherwise you're just wasting time and money on something that will not repair anything. engine additives are comical and I wouldn't even use mmo to start a fire. junk.

I wouldn't exactly consider lifter noise substantial.. If it's lifter noise marvel is definitely the way to go, it's a great product that shows it and has great results. Don't be ignorant about additives. A lot of them are yes, snake oil but that doesn't mean they all are.

If you are not, you sound like one. They might be hiring.

I've used marvel repeatedly on different things. speaking from personal experience - I find it useless.
and lifters are not valves, btw.
