Subject: Re: question about synthetics...

If you already have a small leak in your car, DO NOT use synthetics unless you take care of the leak first. I've used regular oils and I thought I would switch over to Mobile 1. Well, it turns out my crankcase drained out within a week. Normally, I would have to add half a quart every month and a half becuase of the leak. Because synthetics are not as viscous, they have the abilility flow flow into small cracks much easier. This is good in terms of cirulating within your engine, but bad when circulating OUT of your engine. I've switched back to completly using fossil oils. The leaking has slowed down dramatically. As much as I would like to use synthetics, I can't. I've tried mixing 50/50 before, with minimal leak, but I don't know if that's worth doing. So, if you have a leak, not matter how small, get it fixed before using synthetics.
