The skinny on engine oil additives.....

[poltr1]

I have a car with a lot of miles on it. I want to improve my fuel economy and protect my investment by prolonging my engine's life. There are plenty of engine oil additives out there on the market. Some work, some don't. Which ones should I consider and which ones should I avoid?

Right now, my current front-runners are Prolong and Restore.

While doing some research online, I came across this page on carbibles.com regarding additives. They didn't have a lot of good things to say about additives, and many of them have been investigated by the FTC for false claims.

So....if you've used an engine oil additive, what are your experiences?

*nods* My car uses 5W-30 oil.

I think I mentioned this before, but my dealer offers the Envirolution engine cleaning as a way to get rid of engine sludge. Problem is, the dealer -- not the manufacturer -- recommends the service every 12,000 miles. I would think this would be necessary on a less frequent basis.

It's less about extracting the sludge from your engine than extracting the money from your wallet. Here's what the Car Talk guys have to say about it.

Yeah, I think you mentioned that.

Shame that the people who sell car supplies and services -- or anything else, for that matter -- don't proply vet what it is they're selling. :(

I think they know perfectly well what they're selling.
