Me too, if I knew it all I would not still be working at age 62...

So I take it, that this one time deal would be ok? Considering I don't/didn't know the maintenance of the car.

I used synthetic oil, which I'm not sure was the right choice, I've since developed a small leak at the front driver's side corner of the oil pan, so that's my next step and then a built auto tranny. The stock one is starting to slightly slip and stick in first and second.

I wouldn't

There's nothing "wrong" with it, it's just not needed or even desirable (IMHO) on a properly maintained engine. That said, from what you describe your engine may have benefitted from the snake oil.

Oh my goodness, I am in for it here...

Over the years I have had a 50/50 experience with changing over from "dino" to synthetic oil. To sum it up, most higher mileage, virgin (I.e. never broken open), engines I have attempted to switch over have developed weeps and/or leaks when run on synthetic oil. This is because the molecules of synthetic oil are smaller than those of dino oil--much like R-134a vs. R-11.

The smaller molecule size means that seals nd other barriers that held their own with "dino" oil may weep or outright leak with synthetic oil--you have just experienced this.

The good news is that switching back to "dino" oil will more often than not seal things up again; and that although synthetic oil has many properties that make it technically superior to "dino juice", most of those are irrelevant to day-to-day internal combustion engine lubrication requirements. That said, let it be know I run synthetic in my '03 GT.

Ny advice is switch back to conventional oil at the next change, and if you have 100k+ miles use one of the "maxlife" formulations.

I love oil Topics. :0) This isn't about the topic at hand but a good read, none the less.

This is my favorites oil article.

I was listening to you as well if that's what you were talking about. I was being lazy and didn't feel like linking both of you guys. I think you and cliff are some of the most helpful and intelligent people on here. I apologize for my hard headed-ness. You guys along with a lot of other people on the forum have taught me a lot and helped me a lot with my car.

Woh Woh woh, I put my pants on just like the rest of ya, one leg at a time. ...except once my pants are on, I make gold records.

Cliff, I was aware of the smaller molecules. I just decided to switch for peace of mind really. And if it means having to change a gasket here and there, I'm ok with that. The valve cover gaskets are brand new, that's one thing I noticed, So changing out the oil pan one isn't much of a problem.

Sxynerd

Have you ever changed an oil pan gasket before? lol If you had, you wouldn't be so, "Eh whatever"
