O.K., I just read a previous post about "high mileage" oil. That answered most of my questions. But what about products like Z-Max? Do they actually work? I have a 1994 ford f150 4.9 I6. It's my work truck and I love it. Just turned 100,000 and I want it to run another 100k. Will this stuff help? I have to admit oil changes haven't been very regular in the past but doesn't leak any. It burns or blows by about a quart every six months. Thanks!!

No, there is no "fix" in a can. Leave that stuff on the shelf.

The best thing you can do is what you neglected to do for the first 100k, which is regular oil and filter changes . This is the single most important thing you can do for long engine life.

Depending on how much oil it uses in 3000 miles or between oil changes, that is excessive and nearing the wear out stage. Just be regular from here on in and cross your fingers for the next 100k .

You won't find any of that goo in any of my crankcases .
