Talking Thicker oil, and Spark plug gap makes a huge diffence

Well, I've been running 10w-30 Mobil One Synthetic for as long as I have had the turbo (a little over a year) and have'nt had any problems, but I was talking to a few tuners today and they suggested I try 15w-50 in the summer, it will provide more viscosity, allow less blow by, and reduce engine noise. Well, the car has'nt blown any smoke, the motor runs smoother and more quieter And the 10w-30 that was in there was only about 1000miles old, so it was'nt that dirty... By using 15w-50, am I risking hurting the motor at all?

Also, changed the spark plug gap from .032" to .028", and one of the spark plugs I guess I had forgot to gap before, cause it was around .035"... so I regapped them all, and I've noticed smoother idle, and the engine just runs smoother overall..

I'm not sure what made the bigger difference, the plug gap or the oil, but my motor is finnaly running smooth as butter

FWIW, I run the 15w50 in my RS-T (Mobil-1), and really like that weight and viscosity. It's worked well for me.

Would my assumption that it would be bad to have the heavier oil in during the colder parts of winter be correct?

Right, but for those people who don't live in the pits of hades... Was just curious about why it would be ill advised to run the heavier oil normally, or is it?

I would'nt use the 15w-50 in the winter... I'm going to switch it back over to something like 10w-30 for the winter.
