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?

I've never used additives in my oil, I just make sure that I use a GOOD oil. I prefer the Mobil 1 synthetic oil. Yeah, it's a bit more expensive, BUT you can increase you miles between changes from 3000 to 5000. I even had a mechanic tell me that as long as you change the filter ever 5K, you can actually run the oil for 15K. Not sure I'd care to stretch it that far, but it is really good oil. I just had to give up my Chevy Blazer last fall. I had 230K miles on it. It was rusting apart and most everything had been replaced on it, EXCEPT the engine. Even with that high of mileage, and a lot of it done in city driving during the early years (it was a 1990 vehicle), when they parted out the truck, the mechanic wanted to know when I'd had the engine replaced, since he thought that there was NO WAY that it could be in that good of shape with that many miles. It's not the first time a mechanic has said that about our vehicle's engine where we have always run synthetic in it. Just my two cents...
