Valvoline MaxLife
Looking for opinions and stories regarding this product. I started getting small leaks on the driveway after putting in Mobil One synthetic (loss of one quart since November...not bad, just messy) and hope this new stuff may help. It says it's formulated to help old seals.

I know they advertise that the oil helps VALVE seals. I'm not sure about oil leaks. I started using it 2 changes ago in an Acura Legend that began to smoke at 160K. It has stopped smoking but at the same time I swiched oil, I also replaced the PCV valve and went from 10-30 to 10-40. So, I'm not really sure what caused the car to stop using oil but now I'm afraid to switch back to QS dino.

If the MaxLife doesn't help with the little leaks, I will be going back to dino oil with the next change.

Something like a bad PCV valve can cause or increase oil leaks. It doesn't allow the blowby gasses to vent properly, and the pressure in the crankcase forces oil out at the seals, or where ever the weakest place is.

Bad PCV valves can make a big difference!
When your car runs, a certain amount of combustion pressure escapes past the rings and pressurizes the crankcase. Since the returns from things like the cam towers and other parts of the engine are simply open areas in the block, these areas are pressurized too.
I had this happening on my '66 Ford truck. It was always leaking oil from around the valve cover gasket, and blowing it out the breather too, making a mess on the street. Not kewl. I decided to add a chrome valve cover [4.0 liter 6cyl] and change the cover gasket. It leaked like a seive! Oil everywhere, and I had just painted the engine. Torquing the cover bolts slowed the leak, but didn't stop it. A neighbor suggested replacing the ditching the valve, which I did, and also bought an oil fill cover that had a fitting for a tube. I ran the tube into the intake manifold, threw away the PCV, and stopped ALL LEAKS! It doesn't smoke or leak anymore.
I haven't tried this on the shark; I have small amounts of seepage at the front of the cam towers [near the firewall] and a minor leak near the tube that runs from the pan up past the timing belt cover to the top of the engine that I cannot stop for the life of me and which makes a mess on the garage floor [the belt looks safely clean].
