In the past, leakage was a problem. As gasket were exposed to dino
oil, they swelled. When people would switch to syntheitc, they would shrink and leak. That's not the big issue now as it once was.
Syntheitc
oil has two distinct advantages over dino
oil: Better heat tolerance, and longer drain intervals. If you don't need those two advantages, don't waste your money.
There are only 4 true
synthetic oils on the market. And Mobile 1 is not one of them.
