Prolong Engine treatment

I have a 2000 Avalon with 130000 miles…how well does Prolong Engine Treatment work on metal to metal friction reduction?

Let’s see?

The engine got to 130,000 miles by using regular oil?

And now you want to start experimenting with oil additives?

I just don’t get it?



Don’t you think that if it reduced friction, it would already be in your oil?

Just out of curiosity I looked up the stuff… and when I saw the price… .Yikes!! :scream:

It’s “snake oil”. From a very expensive snake.
If you want to prolong your engine’s life, maintain a good (even aggressive) maintenance schedule, monitor your fluid levels regularly, and don’t beat the car up. It’s that simple. You do not need expensive additives, nor will they help.


You’re doing fine with what you are using onw. As others say, don’t start using “snake oil” at this stage when you really don’t need the stuff.

If you’re Avalon isn’t using oil between changes, keep up the good work. You are doing exactly what you should. I imagine you should easily go twice the current miles with standard maintenance.

I hear that motor oil does a pretty good job on protecting metal-to-metal contact in your engine with the additives it already comes with. I don’t think you need to add another additive to your oil.
